Full Text Available We studied the time of initial sexual maturity and the fecundity of the goldfish Carassius auratus under semi-controlled conditions. During the study the water temperature fluctuated from 21 to 30 ºC, the pH between 7 and 8, and the dissolved oxygen between 5.5 and 7 ppm. Sixty days old juvenile fish received prophylactic treatments of brackish water (15 ‰ and methylene blue baths (1 %, and they were fed with live Daphnia magna. The initial sexual maturity occurred between 225 and 233 days of captivity. Mean absolute fecundity was 2 347 (± 302.2 SD ova per gonad, and mean relative fecundity was 63.44 eggs/g fish weight. Gonadosomatic index was between 7.5 and 9.0. Our data will allow ornamental fish producers to calculate the time of initial maturity and fecundity for this species. Rev. Biol. Trop. 54 (4: 1113-1116.

Full Text Available Actualmente, existen metodologías, estándares, modelos de madurez y guías que pueden ayudar a una organización a mejorar su modo de operar. Los modelos de madurez constituyen una evolución de las metodologías para gestionar la calidad de la organización. Fueron concebidos inicialmente para la industria del software, pero actualmente su área de aplicación es muy diversa. La implementación de los modelos de madurez en las pequeñas y medianas empresas (Pymes, se dificulta por ser organizaciones que en general están poco estructuradas y en la mayoría de los casos no cuentan con personal calificado y certificado. El objetivo del trabajo es realizar recomendaciones que puedan servir de referencia para su aplicación en las Pymes, a partir de una revisión de reconocidos modelos de madurez. ABSTRACT Nowadays there are methodologies, standards, maturity models and guides that can help an organization to improve the way it operates. Maturity models are evolving methodologies to manage the quality of the organization. They were initially designed for the software industry, but currently its application area is very diverse. The implementation of maturity models in small and medium enterprises (SMEs is difficult, since these organizations are wrongly structured in general and in most cases they do not have qualified and certified personnel. The main purpose of this paper is to perform recommendations that may be applied by SMEs, starting from a review of recognized maturity models.

Progresos y desafíos en el ejercicio del derecho a la salud sexual y reproductiva en la Argentina de los últimos 40 años. Una aproximación a partir de información relativa a “la primera vez”

Directory of Open Access Journals (Sweden)

Eleonora Soledad Rojas Cabrera

Full Text Available Resumen Este trabajo intenta aproximar la medida en que Argentina ha avanzado, en los últimos 40 años, hacia el pleno ejercicio del derecho a la salud sexual y reproductiva con igualdad de oportunidades. Para ello se utiliza información sobre la primera experiencia sexual, proveniente de la Encuesta Nacional sobre Salud Sexual y Reproductiva, relevada en 2013. En particular, se indaga la proporción de personas iniciadas sexualmente en la adolescencia, según el sexo, el quinquenio de nacimiento y las condiciones en que la experiencia tuvo lugar. Los resultados revelan notables progresos en relación al debut sexual consentido y seguro. Sin embargo, persisten problemas derivados de las diferencias entre sexos, el desconocimiento de mecanismos de protección en determinados casos y, en ocasiones, la falta de acceso a los mismos. Estas cuestiones evidencian la necesidad redoblar los esfuerzos realizados, mediante la incorporación integral de las perspectivas intercultural, de género y de derechos humanos.

Full Text Available Las empresas PYMES del sector metalmecánico de la ciudad de Olavarría aportan a su desarrollo económico pero presentan deficiencias a nivel de productividad, competitividad y en su gestión. Ante esta realidad se hace necesario intensificar el estudio de sus actividades y recursos para mejorar su situación actual. Por tanto, el objetivo es conocer la disponibilidad de recursos tangibles e intangibles y la forma en que los mismos son gestionados en cada una de las actividades empresariales. Para enmarcar el estudio de las actividades y el uso de recursos asociados se recurre a la cadena de valor, complementado con el enfoque basado en recursos. Se recolectan los datos mediante la aplicación de un instrumento, que indaga sobre el uso de recursos relacionados con las actividades primarias y de apoyo. Los recursos tangibles e intangibles son las variables independientes y las variables dependientes son las actividades primarias y de soporte. Luego, se profundiza el diagnóstico a través de un segundo instrumento, que define el nivel de madurez alcanzado en términos de competitividad. Como resultado del diagnóstico y caracterización del estado competitivo de empresas metalmecánicas de Olavarría se obtiene un grado de desarrollo, asociado al uso de los recursos con valores que van desde 49 al 72% para las actividades primarias y desde 55 al 67% para las de soporte. Al evaluar el aprovechamiento de los recursos en la totalidad de las actividades, a través del nivel de madurez, se obtiene un valor promedio asociado al nivel 2, correspondiente al uso ineficiente de recursos. Esto permite concluir que las mismas cuentan con recursos tangibles e intangibles, pero los mismos no son utilizados eficientemente para realizar sus actividades en pos de lograr una ventaja competitiva.

Full Text Available This article studies the proceedings of the «Primeras jornadas eugénicas españolas», which took place in the spring of 1933 after an abortive first attempt in 1928. Study of the two volumes of proceedings provides evidence of the ideological and political framework of the medical and juridical debate about sexuality in the 1920s and 1930s. In 1928, the Primo de Rivera dictatorship intervened to prevent the «pornographic indulgence» represented by the series of planned conferences, cutting off at the root social and political debate on an urgent problem in Spanish society: birth control and family planning. The second congress, in the final months of the «bieno reformador» (1931-1933, reveals the abyss that separated even those groups who appeared politically and ideologically closest. Now that sexuality had been removed from the confession booth, the question of the ethical and juridical limits of state intervention could be raised, and there was little hesitation in expressing viewpoints with an unmistakably totalitarian colour, alongside humanist and feminist perspectives, all of them extremely modern. Sexual difference and identity, maternity and sexuality, and female and sexual emancipation, were themes that, by raising the possibility of another sexual order, allowed the participants in the congress to glimpse the contours of a world that was unprecedented and shocking, even for the most progressive.

Las principales causas apuntan al modo en que es adoptado este paradigma. La complejidad de este proceso debe ser abordada empleando el enfoque evolutivo que ofrecen los modelos de madurez de SOA; sin embargo, la diversidad de estos dificulta la selección y aplicación de alguno. Por lo anterior, el objetivo de este trabajo consistió en realizar un análisis comparativo entre los modelos de madurez más representativos y determinar si son suficientes para evaluar y planificar con efectividad la adopción de SOA. Las insuficiencias detectadas, valoradas integralmente, limitan las capacidades de evaluación y planificación que ofrecen los modelos. Con el propósito de superarlas y empleando la experiencia internacional acumulada en esta materia, fueron definidos los constructos (principios, elementos y estructura que sustentan un modelo de madurez más integral.AbstractThe adoption of Service Oriented Architectures (SOA by the companies shows high failure rates, mainly because of the way this paradigm is adopted. Thus, the complexity of this process should be addressed by using the evolutionary approach that maturity models offer. However, the diversity of maturity models makes difficult the selection and implementation of most of them. Taking this into account, the objective of this paper is to carry out a comparative analysis between the most representative maturity models and to determine whether they are sufficient in order to evaluating and planning the adoption of SOA with effectiveness. The inadequacies detected after a comprehensive assessment, restrict the evaluation and planning capacities that these models offer. In order to overcome them and using the international experience gained in this field, it were defined the constructs (principles, elements and structure that support a more integral

MATERIAL Y MÉTODOS: Se analizó la base de datos de adolescentes de la Encuesta Nacional de Salud 2000, realizada en septiembre de 1999 a marzo de 2000, la cual tuvo un diseño complejo al ser probabilístico, polietápico, estratificado y por conglomerados. La muestra incluyó a adolescentes de entre 12 a 19 años de edad (n=15 241. Se hizo un análisis descriptivo, se aplicó la prueba ji cuadrada (Wald para evaluar diferencias de proporciones, y se construyeron dos modelos de regresión logística para obtener razones de momios. RESULTADOS: El 69.2% de los adolescentes refirió conocer al menos un método de control de la fecundidad. El 16.4% mencionó haber tenido relaciones sexuales, y los hombres iniciaron la actividad sexual antes que las mujeres; es importante mencionar que tan sólo 37% de los adolescentes usaron algún método anticonceptivo en la primera relación sexual. El análisis de regresión logística mostró que los adolescentes del sexo masculino, los de mayor escolaridad, quienes poseían información de algún método anticonceptivo y aquellos que inician esta actividad a una edad mayor tuvieron más probabilidad de usar anticonceptivos en su primera relación sexual. El 55.7% de las mujeres que mencionaron haber iniciado actividad sexual han estado embarazadas. El embarazo en las adolescentes se asoció significativamente con un nivel bajo de escolaridad, con iniciar su vida sexual a edades tempranas y con el hecho de haber estado alguna vez unidas. Conclusiones. En general, la población adolescente que ha tenido relaciones sexuales no utilizó métodos anticonceptivos durante su primera relación, lo cual incrementa la posibilidad de

La exigencia del consumidor en sus características organolépticas hace necesario un estudio detallado acerca de sus propiedades fisicoquímicas y sensoriales. El análisis sensorial se realizó con un panel entrenado de cinco jueces y las muestras de tomate fueron escogidas de acuerdo con parámetros físicos de color (Cuadro 1 y calidad en los seis estados de madurez del fruto. Se empleó el método de perfil descriptivo, con una escala de respuesta de 0 a 10 puntos, con el fin de cuantificar la intensidad de los sabores básicos (dulce, ácido, amargo, salado y umami. Se realizó un diseño aleatorizado en bloques con seis réplicas por cada tratamiento y un nivel de significancia del 5%. Este indicó la inexistencia de diferencias significativas en las intensidades para cada estado de madurez (p≤ 0,05, y la existencia de diferencias significativas en las intensidades para cada sabor básico evaluado (p>0,05. Mediante el perfil sensorial, se logró establecer que en los estados de madurez 1 y 2, el atributo de mayor intensidad fue el ácido, en los estados de madurez 3, 4 y 5, el atributo que sobresalió fue el dulce y en el estado 6, el atributo percibido en mayor grado fue el umami. Los sabores amargo y salado, se percibieron en una baja intensidad, en los diferentes estados de madurez.The tomato (Lycopersicon esculentum, the vegetable more seeding in the country, is considered one of most important by its volume of production and demand.

Full Text Available Resumen. El agraz o mortiño es un frutal promisorio, considerado como un alimento funcional por su contenido de antocianinas, antioxidantes y vitaminas; no obstante, es un fruto altamente perecedero que pierde rápidamente su calidad comercial y nutricional. El objetivo fue evaluar el comportamiento de frutos de agraz cosechados en tres estados de madurez y almacenados en condiciones de refrigeración. Se utilizó un diseño completamente al azar con arreglo factorial 3x3, donde el primer factor fue la temperatura de almacenamiento: 1, 8 y 20 °C; el segundo factor correspondió al estado de madurez: 3, 4 y 5, el cual se estableció de acuerdo al color de la epidermis del fruto. Se realizaron mediciones de calidad del fruto. Los resultados indicaron que los frutos almacenados a 8 °C en estado de madurez 3 y 4 conservaron las características de calidad comercial hasta los 45 días y para el estado 5 sólo hasta los 25 días. Mientras que a temperatura ambiente los frutos conservaron su vida útil hasta los 21 días en los diferente estados de madurez evaluados. Los frutos del estado 3 y almacenados a 1 °C tuvieron mayor firmeza y acidez total titulable, un alto contenido de sólidos solubles totales y la menor relación de madurez. Para mantener la calidad del fruto de agraz por largo tiempo, se recomienda refrigerar los frutos, en el estado 3 de madurez, a 1 °C.Abstract. The Ericaceae agraz or mortiño is a promising fruit, is considered as a functional food for its high content of anthocyanins, antioxidants and vitamins. It is a highly perishable fruit that quickly loses its commercial and nutritional quality. The objective was to evaluate the behavior of unripe fruits harvested at three maturity stages and stored under refrigeration. It was used a completely randomized design with 3x3 factorial arrangement, where the first factor was the storage temperature: 1, 8 and 20 °C; the second factor corresponded to maturity: 3, 4 and 5, which

Full Text Available Cetengraulis mistycetus es una anchoveta americana, que se encuentra localizada en la Costa Americana desde México hasta Perú. Su valor comercial es relevante en la parte interna del Golfo de Nicoya, ya que la flota artesanal tradicional la utiliza como carnada viva para la línea de anzuelos. En el presente estudio, se determinó la edad de la primera madurez sexual en 12,6 cm, la proporción sexual fue de 1:1,2 machos por hembra, para la época de mayor desove. La fecundidad total se estimo entre 48.498 oocitos en las tallas de 16 a 18,9 cm y de 98.278 oocitos en las tallas que van de 19 a 21,9 cm. La fecundidad relativa estimada fue de 813 oocitos por gramo de pez para el primer grupo de talla y de 1.145 oocitos por gramo de pez para el segundo. En el estudio biométrico, solamente la longitud dorsal fue la única relación que varió entre sexos siendo isométrica para hembras y alométrica negativa en machos, en el resto de relaciones el comportamiento entre sexos fue similar.

Las frutas de uchuva se clasificaron, después de la cosecha, en seis fases de coloración de la cascara, así: 0 = verde, 1 = verde amarillo, 2 = amarillo naranja. 3 == naranja claro, 4 = naranja, 5 = naranja oscura y 6 = naranja roja, a los cuales se le determinaron sus propiedades físicas y bioquímicas. Para describir el comportamiento entre las fases de coloración y las variables analizadas se propusieron modelos estadísticos polinomiales hasta el grado sexto. Los resultados mostraron que, durante el desarrollo 1a coloración del fruto aumento, proporcionalmente, su tamaño, peso fresco y la relación solidos solubles totales/acidez total titulable (SST/AIT hasta 1a fase 5, mientras la acidez titulable se redujo constantemente. Los coeficientes de determinación mas altos se encontraron para las variables acidez total titulable (R² = 0,95 y relación SST/ATT (R² = 0,98, y los mas bajos fueron para β-caroteno (R² =0,79. Los solidos solubles (principalmente, sacarosa mostraron sus picos mas altos en las fases 3 y 4 y el contenido del β caroteno, en 1a fase 4, razón por la cual se supone que la madurez fisiológica se encuentra entre estos dos estados (3 y 4, naranja claro - naranja, En el estado de la sobremaduracion, color naranja roja, se observo una reducción marcada en tamaño y peso del fruto. Por la relación estrecha entre coloración y el desarrollo de los ingredientes del fruto, se propone que el color de la cascara es un indicador, de fácil uso en campo, para determinar calidad y madurez de la uchuva.

Full Text Available Introducción: México ha firmado acuerdos internacionales a favor de la erradicación de cualquier tipo de violencia en el trabajo y particularmente respecto al acoso sexual. La legislación federal, en el Código Penal Federal, se encuentra tipificado el delito de hostigamiento sexual, que solamente será punible cuando se cause un perjuicio o daño, y que sólo se procederá contra el hostigador a petición de la parte ofendida. Por esto, la presente investigación ofrece un cuestionario metodológicamente construido para la identificación del hostigamiento sexual en sus primeras manifestaciones. Métodos: Estudio en dos fases: I Entrevistas a profundidad para la validez del contenido, y II Diseño transversal analítico para la validez del constructo. En la primera fase se entrevistaron a 12 trabajadores identificados como hostigadores sexuales o víctimas de estos comportamientos, para elaborar los enunciados que conformaron el cuestionario. Posteriormente, se validó la construcción de dicho cuestionario aplicándoselo a 74 trabajadores de vigilancia empresarial. Resultados: Se llevó a cabo el análisis factorial y determinó 22 ítems adecuados en tres dimensiones: ambiental, emocional y verbal; el 77% de la varianza explicada y 0.80 confiabilidad Alpha de Cronbach. Además, se construyeron 11 ítems que valoraron consecuencias y siete más que indican los procedimientos preventivos en la empresa con formato dicotómico. Finalmente, se evaluó a los trabajadores y el 20% de los trabajadores identificó riesgo, el 7%, consecuencias personales e impacto en la actividad laboral por hostigamiento sexual perpetrado por superiores. Conclusión: El diseño del cuestionario sobre hostigamiento sexual fue psicométricamente válido, de fácil aplicación y calificación para implementarse en las políticas preventivas de riesgos psicosociales en el ámbito laboral.

Full Text Available Las aulas de la nueva modalidad de FP Básica, se caracterizan por presenta r una alta concentración de alumnos con significativas carencias en su madurez emocional y en su alfabetización científica. El siguiente artículo analiza la evol ución de la madurez emocional de 16 al umnos del primer curso de FP Básica de la rama de Peluquería, utilizando las actividades fuer a del contexto escolar como recurso educat ivo para la asignatura de Ciencias de la Naturaleza. Estas actividade s, están diseñadas de forma que se incida tanto en el aspecto cognitivo, como en el emocional, incluyendo ta reas individuales o en equipo y siempre conectando su conocimiento cotidiano con el escolar. Tras la realización de las actividades, los alumnos son entrevistados de cara a analizar una serie de indicadores emocionales predeterminados. Estos indicadores, responden a los antónimos establecidos por Díaz y Flores (2001 y que constituyen la denominada Plantilla General de Indicadores Emocionales. Las respuest as de los alumnos son analizadas ut ilizando una Plantilla Específica de Diferenciales Semánticos, definida a ta l efecto, según tres momentos diferentes en los que se manifiesta la emoción: durante la actividad, en el aula y fuera ya del centro. El tratamiento de los datos obtenidos permite comparar la evolución de la madurez emocional en el tr anscurso de las actividades, observándose una evolución emocional importante entre los estados inicial y final, de manera general, en alumnos de esta tipología.

Son animales gonocóricos, presentan dimorfismo sexual, y los machos tienen el brazo ectocotilizado o copulador. La proporción de sexos fue de 2,1:1,0 a favor de los machos; se determinaron ocho estadios de desarrollo de los ovocitos, durante la ovogénesis. De acuerdo a su comportamiento reproductivo, se estableció la siguiente escala de madurez gonadal: a indiferenciado, b inmaduro, c inicio de maduración, d en desarrollo, e maduros, fl cópula, g postcópula, autofecundación y evacuación, h postevacuación. Las hembras maduras se encontraron preferentemente, en la primavera y verano; los machos maduros a fines de la primavera y en el verano; la cópula se realizó preferentemente durante el verano; la autofecundación y evacuación de los huevos, se evidenciaron en agosto (50%, octubre 50%, noviembre (71,4%, diciembre (33% y enero (33%. La primera madurez en los machos se encontró a los 9,5 cm y en las hembras a los 12,5 cm de la longitud dorsal del cuerpo. Se observó algunas hembras con ovocitos maduros en lisis y con inicio de ovogénesis avanzada de un nuevo ciclo, que evidencia que no todas las hembras mueren después de cuidar los huevos hasta el final de la eclosión.

Full Text Available El presente trabajo intentará explicar las diferentes causas que hicieron del centro de la meseta el núcleo político y burocrático de la Corona de Castilla y León a finales de la Edad Media. Aquel espacio geográfico, comprendido en sus líneas generales entre Burgos y Toledo, concentró, efectivamente, una parte muy significativa de la actividad política e institucional de la Monarquía en un periodo de especial relevancia en la formación del Estado Moderno en tierras castellanas. Este largo proceso, si bien pergeñado durante los siglos XIII y primera mitad del XIV, únicamente se consolidaría tras la llegada al trono castellano de la nueva dinastía Trastámara, en especial durante los reinados de Enrique III y Juan II, alcanzando su madurez plena en tiempos de los Habsburgo con el asentamiento de la hasta entonces corte itinerante, y de buena parte de su aparato burocrático, en Madrid.Ce travail vise à expliquer les différentes causes qui ont fait du centre de la Meseta le noyau politique et administratif de la couronne de Castille et León. Cet espace géographique, compris grosso modo entre Burgos et Tolède a  effectivement concentré une part importante de la vie politique et institutionnelle de la monarchie à une période cruciale pour la formation de l’État moderne en terre castillane. Ce vaste processus, esquissé au cours du XIIIe siècle et de la première moitié du XIVe siècle, ne s’est consolidé qu’avec l’avènement de la nouvelle dynastie Trastamare, en particulier pendant les règnes d’Henri III et de Jean II, pour atteindre sa pleine maturité au temps des Habsbourg, avec la sédentarisation à Madrid de la cour jusque-là itinérante et d’une  bonne partie de l’appareil bureaucratique.

Full Text Available La población adulta es un grupo ascendente en los nuevos diagnósticos de las infecciones de transmisión sexual (ITS y el VIH. El objetivo principal es analizar si el conocimiento sobre el ITS/VIH, la preocupación por las ITS/VIH y el embarazo y la autoeficacia para rechazar relaciones sexuales son predictoras de las conductas sexuales de riesgo en jóvenes y adultos españoles. Participaron 1.106 jóvenes y adultos de ambos sexos, entre los 17 y los 55 años. Los resultados mostraron que ser soltero, homosexual, haberse hecho la prueba del VIH, haber tenido una ITS, tener estudios universitarios e ingresos económicos mensuales de 900 a más de 1.200 euros tenían las puntuaciones más altas en el conocimiento sobre el ITS/VIH. La autoeficacia predijo gran parte de las conductas sexuales vaginales y anales (la edad de inicio del sexo vaginal y anal y el número de parejas con las que se ha mantenido sexo vaginal. Además, se halló que a mayor conocimiento sobre ITS/VIH, mayor edad de inicio del sexo vaginal y mayor uso del preservativo en la primera relación sexual vaginal. Se espera que estos resultados sean útiles para el desarrollo de programas de prevención de ITS/VIH. © 2013 Asociación Española de Psicología Conductual. Publicado por Elsevier España, S.L.

J Akasaki

Full Text Available La cura termal es un proceso utilizado para acelerar las reacciones de hidratación del cemento portland con el objetivo de obtener beneficios de resistencia mecánica a edades tempranas del hormigón, puesto que la temperatura opera en la velocidad de estas reacciones. Para una mejor evaluación de la influencia que ejerce la temperatura sobre el desarrollo de las propiedades mecánicas del concreto, se utiliza el concepto de madurez. El método de madurez estima el desarrollo de las propiedades mecánicas del concreto relacionado con la historia de las temperaturas durante el proceso de curado. La influencia de la temperatura puede ser indicada por la energía de activación (EA aparente. Cuanto mayor sea el valor de la EA, mayor será la potencia necesaria para iniciar la reacción y, por lo tanto, la velocidad de estas reacciones se verá afectada por la temperatura. Este trabajo presenta los resultados de la determinación experimental de la resistencia a la compresión del hormigón fabricado con adición de cenizas de cascarilla de arroz (CCA, producido por la combustión no controlada de la corteza, en cámara abierta, sin control de la temperatura ni del tiempo de combustión. Como propiedad mecánica, se investigó la resistencia a la compresión. Los resultados señalan la influencia de la adición de CCA y su posología en las reacciones de hidratación del cemento y las propiedades mecánicas del hormigón con cura termal.

La escuela fue la principal fuente de información acerca de la prevención del VIH. Fueron observados conocimientos limitados acerca de la prevención del VIH, actitudes favorables al uso del condón, baja percepción de riesgo en sus prácticas, además desconocimiento del estatus serológico, lo que señala la necesidad de invertir en acciones de educación sobre sexualidad y Enfermedades de Transmisión Sexual/SIDA en la universidad.

"Kipling y su sorprendente primera novela"

2013-01-01

Full Text Available Rudyard Kipling aludió a la masonería en varias decenas de escritos. Su fama como escritor le situó en un lugarprivilegiado en las listas confeccionadas por los mediosmasónicos sobre ilustres masones. Sin embargo, suprimer relato de éxito internacional,El Hombre que quiso ser Rey, apenas fue citado entre las obras quemencionaban a la Orden, ni demasiado estudiado. Contrariamente a lo que podría pensarse de un masón queescribe empleando referencias masónicas, Kipling no cayó en la simplicidad del elogio. Así pues, este estudioenfocado a esta primera novela de Kipling pretende, desde el campo académico, abrir las puertas, en el espaciohistoriográfico hispanoamericano, al análisis de este autor y de su obra en clave masónica.

Full Text Available This article proposes a methodology for estimating the striking time for reinforced concrete slab floors build with industrial systems. For this, a study of maturity of concrete used in such construction is performed. To make the maturity curve in the laboratory, the methodology described in ASTM C1074 is implemented by calculating the activation energy for the three proposed methods and measuring the thermal history of the concrete at a controlled temperature. Finally, a reinforced concrete slab floor is monitored and the striking time is estimated. It has been observed that the final setting time is not recommended for striking slabs floors, as recommended by the manufacturers of concrete in Colombia. Striking time obtained is higher than the final setting time, having a difference of up to 11 hours at the most critical case.El presente artículo propone una metodología para la estimación del plazo de descimbrado de forjados construidos con sistemas industrializados. Para esto, se realiza un estudio de madurez de hormigones usados en este tipo de construcción. Con el fin de construir la curva de madurez en laboratorio se implementa la metodología descrita en la ASTM C1074, calculando la energía de activación por los tres métodos propuestos y midiendo el historial térmico de las mezclas a una temperatura controlada. Por último, se realiza la instrumentación en obra de una placa donde se estima la edad de descimbrado. Se ha observado que el tiempo de fraguado final no es un parámetro recomendable para descimbrar las placas, como lo recomiendan las productoras de hormigón en Colombia. La edad de descimbrado obtenida es mayor a la del tiempo de fraguado final, habiendo una diferencia de hasta 11 horas en el caso más crítico.

Cape gooseberry fruits at the maturity stages 3 (yellow greenish or 5 (yellow orange and with calyx drying for 6 hours at 18 or 24ºC, were stored at the temperature of 18ºC and 85 % relative humidity for 20 days, to evaluate physical-chemical and physiological changes. The cape gooseberry, a climacteric fruit, presented the maximum of respiration between 6 and 8 days of storage. The 6th day of storage seems to be crucial due to the very high metabolism and the maximum contents of sugars and acids on this day. Soluble solids tended to increase and the titratable acids went to diminish. The fruit's sugar content was characterized by a major concentration of sucrose, followed by glucose and fructose. While the citric acid showed its highest level at the sixth storage day that of the tartaric acid increased constantly up to 18 days. The fruit maturity stage 3 is that which best conserved the sugars and organic acids evaluated. The maturity index influenced more than calyx drying the postharvest behavior of cape gooseberry. Calyx drying at 24ºC caused the highest climacteric peak and originated the highest loss of fresh weight in fruits harvested at maturity index 5.

Full Text Available En el artículo presentamos el impacto que tuvo sobre la elaboración de los afectos un programa de intervención para favorecer la mentalización, dirigido a diez maestras de primera infancia de la ciudad de Cali. El objetivo fue identificar cambios en el modo de representación y en el nivel de tolerancia de los afectos. El método utilizado fue descriptivo. Evaluamos la forma de representación y el nivel de tolerancia de los afectos basándonos en las categorías del instrumento Verbal Elaboration of Affect (VEA propuesto por Lecours y Bouchard. Se utilizaron narraciones de eventos dolorosos recordados por las maestras al inicio y al final del programa. Los resultados mostraron que hubo cambios positivos en la mentalización del afecto. No obstante en la discusión dejamos abierta la pregunta sobre su permanencia en el tiempo y señalamos la importancia que tiene que las maestras de primera infancia tengan la oportunidad de elaborar sus experiencias emocionales infantiles.

Género e iniciación sexual en México. Detección de diversos patrones por grupos sociales.

Full Text Available La reciente investigación antropológica y sociodemográfica sobre los significados de la sexualidad entre la población mexicana reporta la existencia de un patrón de iniciación sexual diferenciado para hombres y mujeres marcado por el género. Por lo general para los varones la primera relación sexual tiene un carácter ritual, y es llevada a cabo bajo la presión del grupo de pares, ante el cual los jóvenes deben dar prueba de su identidad masculina. En contraste, las mujeres deben mantener una actitud de recato y preservar su virginidad hasta el matrimonio. La iniciación sexual femenina, a diferencia de la masculina, por lo general implica el establecimiento de vínculos emocionales así como el inicio de la inda conyugal y reproductiva. Teniendo en cuenta estos hallazgos, exploramos los datos de la Encuesta Nacional de Salud Reproductiva (Ensar de 2003 para comparar, desde una perspectiva de género, las experiencias de hombres y mujeres de distintas generaciones y grupos sociales. Intentamos detectar los cambios en el tiempo e identificar diversos patrones de iniciación sexual por grupos sociales.

Se les aplicó una encuesta anónima, se procesó la información por el conteo simple, y se representó en tablas estadísticas, con el consiguiente resultado. La mayoría de los adolescentes tuvieron su primera relación sexual entre los 11 y 16 años, y más de la mitad a partir de los 15. El 41 % ha mantenido relaciones sexuales con 2 o más parejas sexuales a la vez, el 79,17 % de los varones no usan condón o lo hacen en algunas ocasiones, y de igual forma las féminas no lo exigen. Solo el 61,34 % usa algún método anticonceptivo, por lo que en las relaciones sexuales se consideran con riesgo de provocar un embarazo en el 55,14 % de los adolescentes, y de contagiarse con infecciones de transmisión sexual en el 46,84 %. Las principales fuentes de información referidas por los adolescentes son los medios de difusión masiva y el Médico de Familia.This cross-sectional descriptive research work studied 239 adolescents from "Batalla de Guisa" polytechnical school in Río Cauto during the first semester of 2001. They were administered an anonymous survey and the data collected were processed by simple counting and represented in statistical tables. The results were the following: most of the adolescents had their first sexual intercourse at the age of 11 to 16 years, more than half of them at the age of 15 years on. 41 % had had sexual relations with 2 or more sexual partners at the same time. 79,17 % of males did not use condom or did it occasionally whereas females did not demand the use of condom. Only 61,34 % used any contraceptive method, therefore sexual relations in 55,14 % of adolescents may be a risk factor for pregnancy and in 46,84 % may be a risk factor for sexually transmitted diseases.

Full Text Available En México, en la actualidad, la investigación demográfica documenta la paulatina postergación de la primera unión y el rejuvenecimiento en la edad a la que inician las relaciones sexuales; es decir, se está observando una iniciación sexual más desvinculada de la unión conyugal. Sin embargo, a diferencia de lo que sucede en el contexto nacional, entre las mujeres y hombres jóvenes en Chiapas observamos el predominio de una sexualidad estrechamente vinculada a la unión conyugal. En este contexto, acudir con trabajadoras del sexo comercial (TSC parece constituirse en la única opción de los varones jóvenes para tener relaciones sexuales antes y fuera del matrimonio. En una investigación cualitativa realizada con jóvenes de entre 15 y 19 años de edad, residentes de tres municipios de la región fronteriza, analizamos las condiciones que permiten la no ocurrencia de un patrón que distinga claramente la iniciación sexual de la vida en pareja, como está documentado en el ámbito nacional.

Aun cuando esta situación, ha despertado el interés en estudios que permitan su reproducción controlada en cautiverio, actualmente es escaso el conocimiento acerca de aspectos reproductivos básicos de esta especie. Dada su importancia, este trabajo describe y caracteriza el proceso completo de maduración gonadal en hembras de Cryphiops caementarius, en base a cambios en la morfología externa e interna del ovario. Hembras adultas extraídas del río Limarí, fueron disectadas y sus ovarios removidos y preparados para análisis histológicos.

Se hace notar el predominio de la colectividad el comercio internacional como también en la actividad industrial especialmente en aquellas que poseían un mayor desarrollo tecnológico. La disminución de la importancia económica y también demográfica de la colectividad británica en Valparaíso, a partir de la década de 1920, se relaciona directamente con la perdida de influencia británica, en nuestro Continente, luego de la Primera Guerra MundialIn this work we analyze the importance of the british immigrants in the economic development of Valparaiso during the first half of twenty century. We highlight their predominance in the international trade and in the industrial activity especially those that reveal a high technological development. The economic and demographic decline of the british immigrants from 1920 is in close relation with the lost of the british influence in Latin America after the First World War

Sexual problems are common during pregnancy, but the proportion of pregnant women who experience sexual distress is unknown. In non-pregnant samples, sexual distress is associated with lower sexual and relationship satisfaction. To identify the proportion of women experiencing sexual distress during pregnancy and to compare the sexual and relationship satisfaction of women who report sexual distress during pregnancy with that of women without distress. Two-hundred sixty-one pregnant women completed a cross-sectional online survey. Women completed validated measurements of sexual functioning (Female Sexual Function Index; score sexual problem), sexual distress (Female Sexual Distress Scale; score ≥ 15 indicates clinically significant distress), sexual satisfaction (Global Measure of Sexual Satisfaction), and relationship satisfaction (Couples Satisfaction Index). Overall, 42% of women met the clinical cutoff for sexual distress. Of sexually active women (n = 230), 26% reported concurrent sexual problems and distress and 14% reported sexual distress in the absence of sexual problems. Sexual distress and/or problems in sexual functioning were linked to lower sexual and relationship satisfaction compared with pregnant women with lower sexual distress and fewer sexual problems. Sexual distress is common during pregnancy and associated with lower sexual and relationship satisfaction. Health care providers should ask pregnant women about feelings of sexual distress. Identifying pregnant women who experience sexual distress and referring them to appropriate resources could help minimize sexual and relationship problems during pregnancy. Vannier SA, Rosen NO.

Full Text Available La formación del discurso en salud mental durante la primera mitad del siglo XX tiene en el Movimiento de Higiene Mental y en el Comité Nacional de Higiene Mental sus principales influencias. Como depositarios de un estilo de pensamiento biomédico, los dos entes mencionados tomaron la vocería en el campo de la salud mental, el cual para la época bajo estudio adolecía de una clara diferenciación conceptual. Con el objeto de comprender la influencia que ejerció este estilo de pensamiento en la formación del discurso en salud mental durante la primera mitad del siglo XX, se desarrollo una revisión de literatura de la época, empleando para tal fin una propuesta teórica que combinó el análisis del discurso de Michel Foucault y la sociología del conocimiento de Ludwik Fleck. Los resultados evidencian una hegemonía del estilo de pensamiento biomédico para abordar la salud mental, representada principalmente en el empleo de la prevención como estrategia de trabajo; de igual forma se constató que fueron los médicos, psiquiatras y salubristas de la época quienes asumieron para sí, como colectivo de pensamiento, la autoridad para hablar y actuar sobre la salud mental de la población, relegando a un segundo plano otros colectivos de pensamiento.

Full Text Available Esta investigación cualitativa de diseño fenomenológico tuvo como objetivo comprender la influencia de la religión en la toma de decisiones sobre sexualidad en estudiantes católicos practicantes. La muestra, seleccionada intencionalmente, estuvo conformada por cuatro hombres y cuatro mujeres, de los cuales dos de cada sexo habían iniciado su vida sexual y dos no. Las entrevistas en profundidad se analizaron con el apoyo del programa Atlas.ti. Las motivaciones para no iniciar su vida sexual se relacionaron con el amor hacia Dios y no convertir sus relaciones en un acto sexual, mientras que para iniciarla se asociaron con la exploración y la madurez espiritual. Los participantes que no habían iniciado su vida sexual estuvieron en contra de los métodos anticonceptivos artificiales al percibirlos como un elemento que solo promueve la satisfacción sexual. Se identificó que la religión influyó en las motivaciones que tuvieron los estudiantes para iniciar o no su vida sexual.

Full Text Available Se estudiaron 89 adolescentes entre 10 y 19 años de edad del consultorio "Los Carritos" del Policlínico Docente "Ramiro Betancourt" de Palma Soriano, con el propósito de indagar acerca de sus concepciones y comportamiento en la esfera sexual. Entre los principales hallazgos figuran que las primeras manifestaciones de actividad sexual en hembras y varones aparecieron en mayor proporción en edades anteriores a la maduración sexual; en la selección de la pareja primaron los criterios morales y aquéllos que respondieron a sus gustos, aunque existió un grupo significativo en el que se constató superficialidad en su elección; las prácticas sexuales más realizadas en el sexo masculino fueron la masturbación y el intercambio de besos y caricias y en el femenino, esta última y las manipulaciónes recíprocas en las zonas más excitables del cuerpo. Resultó interesante el hecho de que estos adolescentes tuvieran un nivel bajo de conocimiento relacionado con las enfermedades de transmisión sexual y su prevención, así como de los métodos anticonceptivos y su utilización.89 adolescents between 10 and 19 years from "Los Carritos" family physician's office of the "Ramiro Betancourt" Teaching Polyclinic, in Palma Soriano, were studied aimed at knowing about their conceptions and behavior in the sexual sphere. Among the main findings it is the fact that the first manifestations of sexual activities in females and males appeared mostly at ages previous to sexual maturity. The moral criteria and likes predominated at the time of selecting a date. The most used sexual practices in the male sex were masturbation and the exchange of kisses and caresses. This latter and the reciprocal manipulations in the most excitable zones of the body were the most common among females. It was interesting to observe that these adolescents had a poor knowledge of sexually transmitted diseases and their prevention, as well as of the contraceptive methods and their

Eugenics, sexual pedagogy and social change: constructing the responsible subject of governmentality in the Spanish Second Republic.

Jiménez-Alonso, Belén

2008-06-01

This study focuses on eugenics in Spain, and more specifically on the 'official' eugenics whose platform was the Primeras Jornadas Eugénicas Españolas (First Spanish Eugenic Days, FSED). The aim of this paper is to relate eugenics to 'governmentality' rather than to State politics alone and to 'Latin eugenics' rather than to 'mainline eugenics'. On the one hand, the FSED were largely centred on the development of a new sexual code which would set Catholic sexual morality aside. For this reason, sexual pedagogy was one of the most relevant topics during the FSED, personal responsibility becoming the first step to social change. The concern about making people play an active role in their own self-regulation is typical of governmentality. The latter refers to societies where power is decentered and where the objective is to structure the field of action of others (the conduct of conduct). On the other hand, the FSED emphasised preventive eugenics such as welfare programmes and health campaigns rather than negative eugenics such as the sterilisation of the unfit. The situation in Spain was mirrored in countries such as Brazil, Argentina and Mexico, which allows us to think about them in terms of 'Latin eugenics' rather than 'mainline eugenics' from countries such as Great Britain, Germany and the USA.

Sexual Arousal and Sexually Explicit Media (SEM): Comparing Patterns of Sexual Arousal to SEM and Sexual Self-Evaluations and Satisfaction Across Gender and Sexual Orientation.

Investigations of patterns of sexual arousal to certain groups of sexually explicit media (SEM) in the general population in non-laboratory settings are rare. Such knowledge could be important to understand more about the relative specificity of sexual arousal in different SEM users. (i) To investigate whether sexual arousal to non-mainstream vs mainstream SEM contents could be categorized across gender and sexual orientation, (ii) to compare levels of SEM-induced sexual arousal, sexual satisfaction, and self-evaluated sexual interests and fantasies between non-mainstream and mainstream SEM groups, and (iii) to explore the validity and predictive accuracy of the Non-Mainstream Pornography Arousal Scale (NPAS). Online cross-sectional survey of 2,035 regular SEM users in Croatia. Patterns of sexual arousal to 27 different SEM themes, sexual satisfaction, and self-evaluations of sexual interests and sexual fantasies. Groups characterized by sexual arousal to non-mainstream SEM could be identified across gender and sexual orientation. These non-mainstream SEM groups reported more SEM use and higher average levels of sexual arousal across the 27 SEM themes assessed compared with mainstream SEM groups. Only few differences were found between non-mainstream and mainstream SEM groups in self-evaluative judgements of sexual interests, sexual fantasies, and sexual satisfaction. The internal validity and predictive accuracy of the NPAS was good across most user groups investigated. The findings suggest that in classified non-mainstream SEM groups, patterns of sexual arousal might be less fixated and category specific than previously assumed. Further, these groups are not more judgmental of their SEM-related sexual arousal patterns than groups characterized by patterns of sexual arousal to more mainstream SEM content. Moreover, accurate identification of non-mainstream SEM group membership is generally possible across gender and sexual orientation using the NPAS. Hald GM

Sexual Narcissism and the Perpetration of Sexual Aggression

McNulty, James K.

2014-01-01

Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women, Study 1 validated the Sexual Narcissism Scale, a new sexuality research instrument with four subscales—Sexual Exploitation, Sexual Entitlement, Low Sexual Empathy, and Sexual Skill. Then, in a sample of 378 men, Study 2 demonstrated that sexual narcissism was associated with reports of the frequency of sexual aggression, three specific types of sexual aggression (unwanted sexual contact, sexual coercion, and attempted/completed rape), and the likelihood of future sexual aggression. Notably, global narcissism was unrelated to all indices of sexual aggression when sexual narcissism was controlled. That sexual narcissism outperformed global assessments of narcissism to account for variance in sexual aggression suggests that future research may benefit by examining whether sexual narcissism and other sexual-situation-specific measurements of personality can similarly provide a more valid test of the association between personality and other sexual behaviors and outcomes (e.g., contraceptive use, infidelity, sexual satisfaction).

2010-12-01

Childhood sexual trauma has been demonstrated to increase survivors' risk for engaging in unrestricted sexual behaviors and experiencing adolescent sexual assault. The current study used the sexual self-schema construct to examine cognitive representations of sexuality that might drive these behavioral patterns. In Study 1 (N = 774), we attempted to improve the content validity of the Sexual Self Schema Scale for child sexual abuse (CSA) survivors, introducing a fourth sexual self-schema factor titled the "immoral/irresponsible" factor. In Study 2 (N = 1150), the potential differences in sexual self-views, as assessed by the four sexual self-schema factors, between CSA survivors and non-victims were explored. In addition, Study 2 evaluated how these sexual self-schema differences may contribute to participation in unrestricted sexual behaviors and risk for sexual assault in adolescence. Results indicated that a history of CSA impacted the way women viewed themselves as a sexual person on each of the four factors. CSA survivors were found to view themselves as more open and possessing more immoral/irresponsible cognitions about sexuality as compared to women who did not have a CSA history. In addition, the CSA survivors endorsed less embarrassment and passionate/romantic views of their sexual selves. The interaction of CSA severity and the sexual self-schemas explained variance in adolescent sexual assault experiences above and beyond the severity of CSA history and participation in risky sexual behaviors. The findings suggest that sexual self-views may serve to moderate the relationship between CSA and adolescent sexual assault. Implications of these findings and directions for future research are discussed.

Sexual media exposure, sexual behavior, and sexual violence victimization in adolescence.

Ybarra, Michele L; Strasburger, Victor C; Mitchell, Kimberly J

2014-11-01

Emerging research suggests sexual media affects sexual behavior, but most studies are based on regional samples and few include measures of newer mediums. Furthermore, little is known about how sexual media relates to sexual violence victimization. Data are from 1058 youth 14 to 21 years of age in the national, online Growing up with Media study. Forty-seven percent reported that many or almost all/all of at least one type of media they consumed depicted sexual situations. Exposure to sexual media in television and movies, and music was greater than online and in games. All other things equal, more frequent exposure to sexual media was related to ever having had sex, coercive sex victimization, and attempted/completed rape but not risky sexual behavior. Longer standing mediums such as television and movies appear to be associated with greater amounts of sexual media consumption than newer ones, such as the Internet. A nuanced view of how sexual media content may and may not be affecting today's youth is needed. © The Author(s) 2014.

Attachment insecurities and women's sexual function and satisfaction: the mediating roles of sexual self-esteem, sexual anxiety, and sexual assertiveness.

Brassard, Audrey; Dupuy, Emmanuelle; Bergeron, Sophie; Shaver, Phillip R

2015-01-01

We examined the potential role of three mediators--sexual self-esteem, sexual anxiety, and sexual assertiveness--of the association between romantic attachment insecurities (anxiety and avoidance) and two aspects of women's sexual functioning: sexual function and sexual satisfaction. A sample of 556 women aged 18 to 30 agreed to complete an online series of validated questionnaires assessing attachment insecurities and several aspects of sexual functioning. Lower sexual self-esteem and higher sexual anxiety mediated the associations between attachment anxiety and lower sexual function and satisfaction. Lower sexual self-esteem and higher sexual anxiety also partially mediated the links between attachment-related avoidance and the two sexual functioning variables. Sexual assertiveness, however, did not mediate these associations. A significant interaction between attachment anxiety and avoidance was also found to predict sexual satisfaction, with women high in avoidance and low in anxiety being the least satisfied. Results are discussed in terms of theoretical and clinical implications.

Las progenies F1 evaluadas de acuerdo al diseño experimental de filas y columnas incompletas con cuatro repeticiones, indican que el número de vainas/nudo está condicionado por efectos aditivos y de dominancia; sin embargo, los efectos aditivos fueron de mayor importancia con una heredabilidad en sentido estrecho moderado (0.49. Por otro lado, el número de vainas/nudo está alta y positivamente correlacionada con el número de vainas/planta y densidad de grano, en las cuales los efectos aditivos fueron de mayor importancia y heredabilidades en sentido estrecho de 0.72 y 0.36, respectivamente. El número de vainas/nudo está alta y negativamente correlacionada con días a floración, días a madurez en verde, largo de vaina, ancho de vaina, peso de grano, altura de planta y altura a la primera vaina, en las cuales excepto en altura de planta y altura a la primera vaina, los efectos aditivos fueron de mayor importancia, con una heredabilidad en sentido estrecho entre 0.19 y 0.81. Para desarrollar variedades con mayor número de vainas por nudo se puede optar por desarrollar variedades con vainas a menor altura, de granos más pequeños y con vainas más delgadas; o variedades con más días a madurez en verde, de granos menos densos, pedúnculo corto y vainas cortas. Las líneas M-2, calle-calle, Pairumani-1, PH-91-3 poseen genes favorables para desarrollar variedades con mayor número de vainas por nudo y por ende mayor cantidad de vainas por planta, pero con vainas pequeñas y delgadas, y de ciclo corto, además de

Zheng, Lijun; Su, Yanchen

This study examined patterns of asexuality in Chinese asexual people in terms of sexual activities, sexual/romantic attraction, and sexual desire. The sample included 227 (64 men and 163 women) asexual participants and 57 (26 men and 31 women) uncertain asexual participants recruited from social networks for asexual people. The control group included 217 (115 men and 102 women) heterosexual participants recruited from general social networks. Participants scoring 40 or higher on the Asexuality Identification Scale were classified as asexual. Asexual participants reported having less frequent masturbation, sexual intercourse experience, and sexual and romantic attraction compared to heterosexual participants. Lower sexual attraction among asexuals indicated that "people who experience little or no sexual attraction" would be a more appropriate definition of asexuality. The pattern of uncertain asexual participants' sexual/romantic attraction and sexual desire was intermediate between heterosexual and asexual participants. Asexual participants scored significantly lower on dyadic sexual desire and slightly lower on solitary sexual desire than heterosexual participants. There were significant differences in sexual activities and solitary sexual desire among romantic orientation categories. Homoromantic participants showed higher dyadic sexual desire and were more likely to engage in masturbation, indicating the heterogeneity among asexual people. The findings indicated that Chinese asexual people showed similar patterns of asexuality as in Western nations. Specifically, asexual people have little or no sexual attraction, non-partner-orientated sexual desire, and are heterogeneous in sexual activities and sexual desire. This implies similar mechanisms underlying the etiology of asexuality across cultures.

To investigate the sexual behavior, sexual relationships, sexual satisfaction, sexual dysfunction and sexual distress in a population of older urban Australian women. In 2004, 474 women participating in the Longitudinal Assessment of Ageing in Women (LAW) Study completed a series of questionnaires about sexuality. They included the Short Personal Experiences Questionnaire (SPEQ), Relationship Assessment Scale (RAS), Female Sexual Distress Scale (FSDS), questions concerning past sexual abuse based on the Sex in Australia Study, and questions comparing present and past sexual interest and activity. The percentage of women with partners ranged from 83.3% in the 40 - 49-year age group to 46.4% women in the 70 - 79-year age group. The sexual ability of partners diminished markedly with age, with only 4.8% of the partners using medication to enable erections. Only 2.5% of women reported low relationship satisfaction. The incidence of sexual distress was also low, being reported by only 5.7% of women. Younger women and women with partners had higher levels of distress than older women. Indifference to sexual frequency rose from 26.7% in women aged 40 - 49 years to 72.3% in the 70 - 79-year age group. Past sexual abuse was recalled by 22.7% of women and 11.6% recalled multiple episodes of abuse. Women who recalled abuse had lower scores for satisfaction with sexual frequency. It appears from this study that there is a wide range of sexual experience amongst aging women, from never having had a sexual partner, to having solitary sex, to having a relationship with or without sex into the seventh decade. As women age, they experience a decrease in sexual activity, interest in sex, and distress about sex. This may be associated with the loss of intimate relationships as part of separation, divorce or bereavement. Decreased sexual activity with aging may be interpreted as a biological phenomenon (part of the aging process) or as sexual dysfunction, or it may be the result of

Dysregulated sexuality and high sexual desire: distinct constructs?

Winters, Jason; Christoff, Kalina; Gorzalka, Boris B

2010-10-01

The literature on dysregulated sexuality, whether theoretical, clinical or empirical, has failed to differentiate the construct from high sexual desire. In this study, we tested three hypotheses which addressed this issue. A sample of 6458 men and 7938 women, some of whom had sought treatment for sexual compulsivity, addiction or impulsivity, completed an online survey comprised of various sexuality measures. Men and women who reported having sought treatment scored significantly higher on measures of dysregulated sexuality and sexual desire. For men, women, and those who had sought treatment, dysregulated sexuality was associated with increased sexual desire. Confirmatory factor analysis supported a one-factor model, indicating that, in both male and female participants, dysregulated sexuality and sexual desire variables loaded onto a single underlying factor. The results of this study suggest that dysregulated sexuality, as currently conceptualized, labelled, and measured, may simply be a marker of high sexual desire and the distress associated with managing a high degree of sexual thoughts, feelings, and needs.

En aves playeras las marcas melánicas son distintas entre sexos y muy variables; se cree que cumplen una función disruptiva con el paisaje. Analizamos el dimorfismo sexual en tamaño corporal y en la estructura de la barra frontal del chorlo nevado (Charadrius nivosus y encontramos que el tarso, la cuerda alar y que tanto la longitud como la amplitud de la barra frontal son de mayores dimensiones en los machos. Además, describimos por primera vez un ornamento con forma de “cuernos” en la frente, exclusivo de los machos. Aunque otros autores han revisado la variabilidad de estas marcas, su valor adaptativo es poco conocido. Consideramos que el dimorfismo en la estructura de la barra frontal es importante dentro y entre sexos durante la temporada reproductora, ya que cumple un papel clave durante los despliegues de cortejo y en la competencia entre machos, donde son exhibidas las plumas del pecho que contrastan con esta marca. Además, las medidas morfométricas mayores en los machos son consistentes con la poliandria y la competitividad intensa entre los machos.

The importance of feeling sexually attractive: Can it predict an individual's experience of their sexuality and sexual relationships across gender and sexual orientation?

Science.gov (United States)

Amos, Natalie; McCabe, Marita

2017-10-01

Limited research exists on the implications of feeling sexually attractive for various aspects of sexuality and sexual relationships. This article examined associations between self-perceived sexual attractiveness and sexual esteem, sexual satisfaction and amount of sexual experience, among both men and women who identified as heterosexual (n = 1017), gay or lesbian (n = 1225) or bisexual (n = 651). Results of the study demonstrated that positive self-perceptions of sexual attractiveness predicted greater sexual esteem, greater sexual satisfaction, a higher frequency of sexual activity with others and a larger number of sexual partners among both men and women who identified as heterosexual, gay, lesbian or bisexual. The findings suggest that feeling sexually attractive may have implications for how an individual experiences their sexuality and sexual relationships regardless of their gender or sexual orientation. The importance of considering an individual's self-perceptions of sexual attractiveness when they present with concerns related to their sexual experiences or relationships, and the potential benefits of educational and therapeutic interventions designed to enhance self-perceptions of sexual attractiveness are discussed. © 2015 International Union of Psychological Science.

Data from 185 women 50 years of age and older (M = 59.46, SD = 6.96) were used to examine the relationships between sexual excitation (SE) and sexual inhibition (SI) and their lower-order factors to indicators of sexual well-being (i.e., sexual functioning, satisfaction, distress, frequency of sexual activity, and breadth of sexual behavior). Possible moderating factors were also explored. Independently, SE and SI were associated with the majority of the indicators of sexual well-being, and the directions of associations were consistent with the tenets of the DCM. SE and SI lower-order factors were significant predictors of sexual function, satisfaction, and frequency of sexual activity. Sexual distress was predicted more strongly by SI factors and breadth of sexual behavior by one SE lower-order factor (arousability). Partner physical and mental health and participant's own mental health were identified as moderating variables of these associations. Findings of this study are discussed considering the contribution of the DCM to understanding the role of diversity in older women's sexual well-being.

There is growing recognition that youth sexual health entails a broad range of physical, emotional and psychosocial responses to sexual interactions, yet little is known about sexual dysfunctions and well being in youth populations. This study explored sexual dysfunctions among youth and its associations with other domains of sexual health. Sexual dysfunctions were defined as: problems related to orgasm, pain during intercourse, lack of sexual desire or sexual pleasure. Data were drawn from the 2010 French national sexual and reproductive health survey comprising a random sample of 2309 respondents aged 15-24 years. The current analysis included 842 females and 642 males who had sexual intercourse in the last 12 months. Chi square tests were used to test for differences in sexual dysfunctions by sex and explore associations with other domains of sexual health. Half of females (48%) reported at least one sexual dysfunction versus 23% of males. However, over half (57%) of youth reporting at least one dysfunction did not consider this to hinder their sexuality. Altogether, 31% of females cited at least one sexual dysfunction hindering their sexuality-more than three times the 9% of males. Sexual dysfunction was strongly and inversely related to sexual satisfaction for both males and females and additionally to a recent diagnosis of STI or unintended pregnancy for females. Sexual dysfunctions hindering sexuality were also correlated with a history of unintended pregnancy among males. While most youth in France enjoy a satisfying sexual life, sexual dysfunction is common, especially among females. Public health programs and clinicians should screen for and address sexual dysfunction, which substantially reduce youth sexual wellbeing.

In previous studies, number of sexual partners and sexual assertiveness were examined as independent risk factors for sexual victimization among college women. Using a sample of 335 college women, this study examined the interaction of number of sexual partners and sexual assertiveness on verbal sexual coercion and rape. Approximately 32% of the sample reported unwanted sexual intercourse, 6.9% (n = 23) experienced verbal sexual coercion, 17.9% (n = 60) experienced rape, and 7.2% (n = 24) experienced both. As number of sexual partners increased, instances of verbal sexual coercion increased for women low in relational sexual assertiveness but not for women high in relational sexual assertiveness. A similar relationship was not found for rape. Among women who experienced both verbal sexual coercion and rape, increases in number of partners in the context of low refusal and relational assertiveness were associated with increases in verbal sexual coercion and rape. Findings suggest sexual assertiveness is related to fewer experiences of sexual coercion.

Beyond Sexual Orientation: Integrating Gender/Sex and Diverse Sexualities via Sexual Configurations Theory.

Science.gov (United States)

van Anders, Sari M

2015-07-01

Sexual orientation typically describes people's sexual attractions or desires based on their sex relative to that of a target. Despite its utility, it has been critiqued in part because it fails to account for non-biological gender-related factors, partnered sexualities unrelated to gender or sex, or potential divergences between love and lust. In this article, I propose Sexual Configurations Theory (SCT) as a testable, empirically grounded framework for understanding diverse partnered sexualities, separate from solitary sexualities. I focus on and provide models of two parameters of partnered sexuality--gender/sex and partner number. SCT also delineates individual gender/sex. I discuss a sexual diversity lens as a way to study the particularities and generalities of diverse sexualities without privileging either. I also discuss how sexual identities, orientations, and statuses that are typically seen as misaligned or aligned are more meaningfully conceptualized as branched or co-incident. I map out some existing identities using SCT and detail its applied implications for health and counseling work. I highlight its importance for sexuality in terms of measurement and social neuroendocrinology, and the ways it may be useful for self-knowledge and feminist and queer empowerment and alliance building. I also make a case that SCT changes existing understandings and conceptualizations of sexuality in constructive and generative ways informed by both biology and culture, and that it is a potential starting point for sexual diversity studies and research.

The purpose of this study was to test a model of sexual self-concept and sexual risk cognition affecting sexual communication in Taiwanese adolescents. Parent-adolescent sexual communication has been shown to influence adolescent sexual behaviour. Self-concept is an important predictor of human behaviour, especially sexual behaviour. Few researchers have assessed sexual self-concept in adolescents, despite its clear relevance to understanding adolescent sexual behaviour. A cross-sectional survey with convenience sampling was used in this study. In 2009, data were collected by questionnaire from 748 adolescent students at a junior college in Taiwan. The results revealed that the postulated model fits the data from this study well. Sexual self-concept significantly predicts sexual risk cognition and sexual communication. Sexual risk cognition significantly predicts sexual communication and has an intervening effect on the relationship between sexual self-concept and sexual communication. Sexual risk cognition is important in explaining sexuality in adolescents. Sexual self-concept has both direct and indirect effects on sexual communication. Our findings provide concrete directions for school educators in developing sexual health programmes to increase adolescent sexual self-concept and sexual communication with their parents. Future sexual health programmes about sexual self-concept and sexual risk cognition must add for increasing adolescent's sexual communication with their parents. © 2010 Blackwell Publishing Ltd.

Full Text Available Rhinobatos percellens es capturada en Venezuela por la flota artesanal que opera con redes de fondo. Está clasificada por la IUCN como casi amenazada, y no existen estudios sobre su biología o pesquería en el país. Por ello, se analizaron desembarques de la pesca artesanal de playa la Pared (isla de Margarita durante enero-diciembre 2007. A cada ejemplar capturado se le determinó la longitud total, sexo y madurez. Fueron analizados 210 ejemplares, 159 hembras y 51 machos. El 81% de los ejemplares se encontraban maduros y un 27% de este grupo correspondió a hembras grávidas. La talla media de madurez sexual quedó ubicada en 51 y 52cm para hembras y machos, respectivamente. Se detectaron hembras maduras todo el año, y hembras grávidas en siete meses. Fueron analizados 96 embriones con tallas entre 2-19cm, siendo la fecundidad máxima cuatro embriones. La variación de las longitudes de los embriones entre los meses del año indican dos picos máximos de alumbramiento al año pero no existe una sincronía en la cópula ya que la especie se reproduce prácticamente todo el año. Se recomienda elaborar regulaciones pesqueras que incluyan una talla mínima de captura en función de la talla de madurez señalada y liberar las hembras grávidas al agua.

Sexual orientation disparities in sexually transmitted infections: examining the intersection between sexual identity and sexual behavior.

Everett, Bethany G

2013-02-01

The terms MSM (men who have sex with men) and WSW (women who have sex with women) have been used with increasing frequency in the public health literature to examine sexual orientation disparities in sexual health. These categories, however, do not allow researchers to examine potential differences in sexually transmitted infection (STI) risk by sexual orientation identity. Using data from the National Longitudinal Survey of Adolescent Health, this study investigated the relationship between self-reported STIs and both sexual orientation identity and sexual behaviors. Additionally, this study examined the mediating role of victimization and STI risk behaviors on the relationship between sexual orientation and self-reported STIs. STI risk was found to be elevated among heterosexual-WSW and bisexual women, whether they reported same-sex partners or not, whereas gay-identified WSW were less likely to report an STI compared to heterosexual women with opposite sex relationships only. Among males, heterosexual-identified MSM did not have a greater likelihood of reporting an STI diagnosis; rather, STI risk was concentrated among gay and bisexual identified men who reported both male and female sexual partners. STI risk behaviors mediated the STI disparities among both males and females, and victimization partially mediated STI disparities among female participants. These results suggest that relying solely on behavior-based categories, such as MSM and WSW, may mischaracterize STI disparities by sexual orientation.

Establishing a model of sexual assault reflecting psychosocial and behavioral characteristics of perpetrators of sexual killing and rape is necessary for development in risk assessment and intervention. Methodological variations in defining sexual killing have amalgamated serial and non-serial offenders and perpetrators with direct and indirect associations between killing and sexual arousal. This study defined sexual killing specifying that killing should be directly linked to sexual arousal, and sampled 48 sexual killers, operationalized to include only those engaging in post-mortem sexual interference, with one or two known female victims (non-serial), from prison service national (England and Wales) databases. These sexual killers were compared with 48 non-homicide, life or indeterminately sentenced sexual aggressors on psychological and crime scene characteristics. Contrary to previous research, fatal outcomes were associated with neither stranger victims nor weapon presence; sexual killing was characterized by severity of violence less so than non-fatal assault. Sexual killers more often reported problems with emotional loneliness, empathic concern, and sexual entitlement than the sexual aggressors. Theoretical and applied implications are discussed.

One main source of sexual socialization lies within family interactions. Especially sexuality-specific parenting may determine adolescents' sexual development-adolescents' sexual behavior and sexual risk behavior, sexualized media consumption and permissive sexual attitudes-to a significant extent, but different ideas exist about how this works. In this longitudinal study, we examined two hypotheses on how sexuality-specific parenting-parenting aimed specifically at children's sexual attitudes and behaviors-relates to adolescents' sexual development. A first buffer hypothesis states that parents' instructive media discussions with their children-called instructive mediation-buffers the effect of sexualized media consumption on adolescents' sexual attitudes and behavior and, vice versa, the effect of adolescents' sexual attitudes and behavior on sexualized media consumption. A second brake hypothesis states that parents, by communicating love-and-respect oriented sexual norms, slow down adolescents' development toward increased sexualized media use, permissive sexual attitudes, and sexual behavior and sexual risk behavior. Using four-wave longitudinal data from 514 Dutch adolescents aged 13-16 years (49.8% female), we found evidence to support a brake effect. More frequent parental communication of love-and-respect oriented sexual norms was associated with less permissive sexual attitudes and, for boys, with less advanced sexual behavior and a less rapid increase in sexual risk behavior. Parents' instructive mediation regarding adolescents' sexualized media consumption was associated with less permissive sexual attitudes at baseline, but only for girls. No systematic evidence emerged for a buffer effect of parents' instructive mediation. In conclusion, although our data seem to suggest that parent-child communication about sex is oftentimes "after the fact", we also find that more directive parental communication that conveys love-and-respect oriented sexual norms

Inmunidad bucal en la primera infancia

Full Text Available La aparición precoz de enfermedades bucales infecciosas y transmisibles en niños, como caries dentales y enfermedad periodontal, resulta de un desequilibrio entre los mecanismos defensivos del huésped y la virulencia de microorganismos presentes en el medio bucal, a favor de estos últimos. La erupción dentaria que comienza desde el primer año de vida brinda nuevos hábitat a las bacterias en el medio bucal como la superficie del esmalte dental y el surco gingival en el paradencio de inserción dentaria, propicios para el desarrollo de especies bacterianas cariogénicas y/o paradenciopáticas. Este desarrollo es favorecido por condiciones adversas como dieta rica en azúcares fermentables, higiene bucal deficitaria, malposiciones dentarias, escasa secreción salival, hábitos prolongados nocivos como succión no nutritiva, respiración bucal, masticación mínima por ingesta de alimentos que casi no requieren procesamiento para ser deglutidos. Es prioritario controlar los circuitos de infectividad bucal, especialmente durante la primera infancia, cuando el sistema inmune del niño aún está inmaduro y comienza a tomar contacto con antígenos. La madre por el estrecho vínculo físico con su hijo resulta el principal transmisor de gérmenes, sumado a la fase de reconocimiento oral del niño de su propio cuerpo y el entorno. Pese a ello el niño cuenta desde el nacimiento con mecanismos de defensa innatos y otros adquiridos pasivamente en la gestación y a través de la lactancia materna, que dificultan el desarrollo de enfermedades infecciosas bucales y sistémicas

Sexual education plays an essential role in preventing unplanned pregnancy and the transmission of sexually transmitted infections (STIs). School-based sexual education programs, in particular, may be well positioned to address social factors that are empirically linked to negative sexual health outcomes, such as traditional social norms surrounding gender and sexuality. However, youth are seldom granted access to sexual education programs that explicitly address these issues. This study presents findings from a pretest-posttest survey of a sexual education program that did. It was designed for eighth graders (N=95) in the context of a school-community collaboration. The study assessed the links between several components of sexual empowerment, including gender ideology, sexual knowledge, and contraceptive beliefs. Findings link participation in the sexual education program to more progressive attitudes toward girls and women, less agreement with hegemonic masculinity ideology, and increases in sexual health and resource knowledge. Structural equation models suggest that traditional attitudes toward women were significantly related to hegemonic masculinity ideology among both boys and girls, which was in turn negatively related to safer contraceptive beliefs.

Livingston, Jennifer A; Testa, Maria; VanZile-Tamsen, Carol

2007-03-01

Low sexual assertiveness has been proposed as a possible mechanism through which sexual revictimization occurs, yet evidence for this has been mixed. In this study, prospective path analysis was used to examine the relationship between sexual refusal assertiveness and sexual victimization over time among a community sample of women. Results provide support for a reciprocal relationship, with historical victimization predicting low sexual assertiveness and low sexual assertiveness predicting subsequent victimization. The effect of recent sexual victimization on subsequent sexual assertiveness also was replicated prospectively. These findings suggest that strengthening sexual assertiveness may help reduce vulnerability to future victimization.

The current study examined sexual victimization and two barriers to young women's sexual assertiveness: fear of sexual powerlessness and cognitive emotion dysregulation. College women (N = 499) responded to surveys and indicated that fear of sexual powerlessness and, to a lesser extent, cognitive emotion dysregulation were barriers to sexual assertiveness. Compared with nonvictims, sexually victimized women had greater problems with sexual assertiveness, fear of sexual powerlessness, and cognitive emotion dysregulation. Among victims, fear of sexual powerlessness and emotion dysregulation interacted to impede sexual assertiveness. Findings support targeting identified barriers in interventions to improve sexual assertiveness and reduce risk for unwanted sexual experiences and sexual victimization.

Subjective sleep quality, unstimulated sexual arousal, and sexual frequency

Full Text Available Introduction: REM sleep deprivation increases unstimulated erections in rats, and total sleep deprivation increases erections during audiovisual sexual stimulation in men, but the effects of sleep problems on human unstimulated sexual arousal are unknown. Objective: We examined the associations of subjective sleep quality with unstimulated sexual arousal, satisfaction with sex life, and sexual frequency and desire over the past month. Methods: 275 Portuguese (169 women reported their anxiety, sexual arousal and sexual desire during a resting state, and completed the Pittsburgh Sleep Quality Index, the sexual satisfaction subscale of the LiSat scale, the Desire dimensions of the Female Sexual Function Index (women only and International Index of Erectile Function (men only. They additionally reported how many days in the past month they engaged in penile-vaginal intercourse, noncoital sex, and masturbation. Salivary testosterone (T was assayed by luminescence immunoassays. Results: Poorer sleep quality correlated with greater unstimulated sexual arousal in men with higher T levels and in women with higher T levels not taking oral contraceptives. In women with lower T, poorer subjective sleep quality correlated with greater sexual dissatisfaction. In both sexes, sleep quality was uncorrelated with sexual desire and sexual frequency over the past month. Discussion: Consistently with other studies in humans and animals, the findings are congruent with the notion that lack of sleep can increase sexual arousal, but not sexual frequency. T might play a role in the sexual arousal caused by lack of appropriate sleep.

Multidimensional sexual perfectionism.

Perfectionism is a multidimensional personality characteristic that can affect all areas of life. This article presents the first systematic investigation of multidimensional perfectionism in the domain of sexuality exploring the unique relationships that different forms of sexual perfectionism show with positive and negative aspects of sexuality. A sample of 272 university students (52 male, 220 female) completed measures of four forms of sexual perfectionism: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. In addition, they completed measures of sexual esteem, sexual self-efficacy, sexual optimism, sex life satisfaction (capturing positive aspects of sexuality) and sexual problem self-blame, sexual anxiety, sexual depression, and negative sexual perfectionism cognitions during sex (capturing negative aspects). Results showed unique patterns of relationships for the four forms of sexual perfectionism, suggesting that partner-prescribed and socially prescribed sexual perfectionism are maladaptive forms of sexual perfectionism associated with negative aspects of sexuality whereas self-oriented and partner-oriented sexual perfectionism emerged as ambivalent forms associated with positive and negative aspects.

Child sexual abuse, links to later sexual exploitation/high-risk sexual behavior, and prevention/treatment programs.

This paper reviews the literature on the nature and incidence of child sexual abuse, explores the link between child sexual abuse and later sexual exploitation, and reviews the literature on prevention strategies and effective interventions in child sexual abuse services. Our understanding of the international epidemiology of child sexual abuse is considerably greater than it was just 10 years ago, and studies from around the world are examined. Childhood sexual abuse can involve a wide number of psychological sequelae, including low self-esteem, anxiety, and depression. Numerous studies have noted that child sexual abuse victims are vulnerable to later sexual revictimization, as well as the link between child sexual abuse and later engagement in high-risk sexual behaviour. Survivors of child sexual abuse are more likely to have multiple sex partners, become pregnant as teenagers, and experience sexual assault as adults. Various models which attempt to account for this inter-relationship are presented; most invoke mediating variables such as low self-esteem, drug/alcohol use, PTSD and distorted sexual development. Prevention strategies for child sexual abuse are examined including media campaigns, school-based prevention programmes, and therapy with abusers. The results of a number of meta-analyses are examined. However, researchers have identified significant methodological limitations in the extant research literature that impede the making of recommendations for implementing existing therapeutic programmes unreservedly.

Sexual Regret

2016-12-01

Full Text Available The current study sought to answer three key questions about explaining the emotion of regret in the domain of casual sex: Are sex differences in sexual regret robust or attenuated in a highly egalitarian culture? What proximate psychological variables might explain sex differences in sexual regret? And what accounts for within-sex variation in experiences of sexual regret about casual sex. We conducted a study of 263 Norwegian students (ages 19–37 who reported how much they regretted having either engaged in, or passed up, their most recent casual sexual experience. Sex differences in sexual regret are not attenuated in this sexually egalitarian culture. The study revealed sex differences in worries about pregnancy, STIs, and reputation; however, these predictors did not succeed in accounting for the sex differences in regret engaging in casual sex. Sexual gratification and socio-sexual orientation both predicted the sex differences in casual sex regret. In contrast, only socio-sexual orientation attenuated the sex difference in regret passing up casual sex. Predictors of within-sex variation in casual sexual regret included worry about sexual reputation, experienced gratification during the encounter, and socio-sexual orientation. Discussion focuses on implications for the psychological design features of this relatively neglected emotion.

To see if mothers who were sexually abused in their own childhood are at increased risk of their children being sexually abused and to see if prior sexual abuse in mothers affects their parenting abilities. Sixty-seven mothers whose children had been sexually abused by others and 65 control mothers were asked about sexual abuse in their own childhood. The sexually abused children of mothers who had been sexually abused in their own childhood were compared with the sexually abused children of mothers who had not suffered child sexual abuse as children. Comparisons were made on self-esteem, depression and behavior in the children. Thirty-four percent of mothers of sexually abused children gave a history of sexual abuse in their own childhoods, compared with 12% of control mothers. Assessment of the sexually abused children for self-esteem, depression and behavior at the time of diagnosis, after 18 months and after 5 years showed no difference in any of these measures at any of the three time intervals between those whose mothers had suffered child sexual abuse and those whose mothers had not been abused. In this study, sexual abuse in a mother's own childhood was related to an increased risk of sexual abuse occurring in the next generation, although prior maternal sexual abuse did not effect outcome in children who were sexually abused.

Sexual Narcissism and the Perpetration of Sexual Aggression

OpenAIRE

Widman, Laura; McNulty, James K.

2009-01-01

Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women,...

2004-08-01

Full Text Available Abstract Health Issue Much attention is devoted to women's reproductive health, but the formative and mature stages of women's sexual lives are often overlooked. We have analyzed cross-sectional data from the Sexual Behaviour module of the 2000/2001 Canadian Community Health Survey (CCHS, and reviewed the literature and available indicators of the sexual health of Canadian women. Key Findings Contemporary Canadian adolescents are becoming sexually active at younger ages than in previous generations. The gender gap between young males and females in age at first intercourse has virtually disappeared. The mean age at first intercourse for CCHS respondents aged 15–24 years was between 16 and 17. Canadian-born respondents are significantly younger at first intercourse than those who were born outside of Canada. Few adolescents recognize important risks to their sexual health. Older Canadians are sexually active, and continue to find emotional and physical satisfaction in their sexual relationships. Data Gaps and Recommendations Both health surveys and targeted research must employ a broader understanding of sexuality to measure changes in and determinants of the sexual health of Canadians. There is reluctance to direct questions about sexual issues to younger Canadians, even though increased knowledge of sexual health topics is associated with delayed onset of sexual intercourse. Among adults, sex-positive resources are needed to address aspects of aging, rather than medicalizing age-related sexual dysfunction. Age and gender-appropriate sexual health care, education, and knowledge are important not only for women of reproductive age, but for Canadians at all stages of life.

Sexual Orientation as Interpretation? Sexual Desires, Concepts, and Choice

Directory of Open Access Journals (Sweden)

Díaz-León E.

2017-07-01

Full Text Available Are sexual orientations freely chosen? The idea that someone’s sexual orientation is not a choice is very influential in the mainstream LGBT political movement. But do we have good reasons to believe it is not a choice? Going against the orthodoxy, William Wilkerson has recently argued that sexual orientation is partly constituted by our interpretations of our own sexual desires, and we choose these interpretations, so sexual orientation is partly constituted by choice. In this paper I aim to examine the question of whether our interpretations of our own sexual desires are constitutive of our sexual orientations. I will argue that whereas Wilkerson’s argument for the claim that sexual orientations are in part constituted by our chosen interpretations of our sexual desires is not sound, there are good reasons for endorsing a weaker claim, namely, that there are different but equally apt descriptions of the same sexual desires, depending on which concepts we have.

Education in human sexual physiology and pathology, as well as own sexual health of medical doctors determines in a large proportion the ability to talk with patients about their sexual disorders. Therefore the authors considered important to collect and assess data regarding sexual health and development of Medical Faculty students. Analysis of selected aspects of psychosexual development and sex life of IVth grade medical students. We applied the self-report Questionnaire of Satisfaction with Sexual Life (KSS2), an instrument created to assess sexual problems in patients treated with group psychotherapy. Medical students filled the questionnaire when attending the courses of Psychopathology of neurotic disorders or Psychotherapy. Analysis of the collected data revealed a relatively high differentiation of the studied group in regard of satisfaction and experiences with sexual life, attitudes towards masturbation, relationships and sexual activity. Regarding some aspects, significant differences between women and men occurred. A set of factors were identified, some of them may negatively influence medical doctor's competencies in the domain of sexual health. These are not having sexual debut or even lack of any erotic experiences and lack of sexual satisfaction. The results indicate a significant prevalence of factors, which may impede students education as well as taking into consideration the sexual issues during the medical interview. Assessment of influence of students' and doctors' own sexuality on their competencies in diagnostics and treatment requires further studies.

Ullman, Sarah E.; Vasquez, Amanda L.

2015-01-01

This study examined sexual risk behaviors and sexual refusal assertiveness in relationship to child sexual abuse (CSA), emotion dysregulation, and adult sexual revictimization. Path analyses of 1,094 survivors who had sex in the past year were done to examine sexual risk behavior, and sexual refusal assertiveness mediational pathways by which CSA severity and emotion dysregulation may affect revictimization over one year in adult female sexual assault survivors. Exchanging sex for money and sexual refusal assertiveness were significantly associated with emotion dysregulation, whereas exchanging sex for money, and not sexual refusal assertiveness, was only significantly related to CSA severity. Both exchanging sex for money and sex refusal assertiveness mediated the relationship between emotion dysregulation and adult sexual revictimization. Exchanging sex for money mediated the CSA severity-revictimization relationship. These findings demonstrate the importance of considering both risky and protective sexual behaviors in research and prevention programming that address sexual revictimization in women. PMID:25942287

This study investigated the role of sexual and physical abuse, sexual self-schema, sexual functioning, sexual knowledge, relationship adjustment, and psychological distress in 87 women matched on age, relationship status, and parity and assigned to 3 groups--vaginismus, dyspareunia/vulvar vestibulitis syndrome (VVS), and no pain. More women with vaginismus reported a history of childhood sexual interference, and women in both the vaginismus and VVS groups reported lower levels of sexual functioning and a less positive sexual self-schema. Lack of support for traditionally held hypotheses concerning etiological correlates of vaginismus and the relationship between vaginismus and dyspareunia are discussed.

Sexual fears, sometimes in the form of phobias, lead to aversive or sexually avoidant behavior blocking sexual closeness and resulting in deep personal and interpersonal distress. To determine the types of sexual fears and aversive behavior in young people of reproductive age (students) and their degree of markedness as to encourage a further implementation of prevention programs and interventions. The study included 116 fifth-year medical students in Plovdiv Medical University. Of these, 55 men and 61 women were assessed with the Sexual Aversion Scale, a 30-item self-rating questionnaire. The Diagnostic and Statistical Manual of Mental Disorders criteria of sexual aversion were used. The statistical analyses used were descriptive statistics and independent samples t-test. Sexual fears and aversive or blocking behavior are mild to moderate, mean score of 1.54 ± 0.04, without statistically significant gender differences. Both sexes have established fear-related sexual aversive motives of sexual behavior related to the risk of unwanted pregnancy and HIV infection. Women have significantly higher average scores for the following statements: fear of sexual intercourse (1.61 vs 1.25), avoidance of situations in which they may be involved sexually (1.95 vs 1.51), avoidance of genital sexual contact (1.44 vs 1.16), fear of catching a sexually transmitted disease (2.46 vs 2.09 ), fear of pregnancy (2.61 vs 2.15) and concerns what other people think of them (2.34 vs 1.93 ). Sexual fears and aversive or blocking behavior were mild to moderate. In both sexes similar fears--aversive or blocking patterns of sexual behavior were found, mainly associated with the fear of unwanted pregnancy and the risk of HIV infection, more expressed in women.

2015-01-01

Male sexual dysfunction is a prevalent and distressing condition, which may be exacerbated by the sufferer's perceptions of masculinity and normative sexual behavior. This study sought to investigate the effect of social context on males' beliefs regarding sexual behavior. The research examined the effect of male role modeling and masculine cues on males' dysfunctional sexual beliefs, sexual attitudes, and self-perceptions of sexual functioning. A sample of 140 male participants, with a mean age of 29 years, was exposed to pictorial and verbal cues that presented different versions of male behavior across three conditions. Results indicated that males exposed to models and cues of traditional masculinity showed significantly increased levels of dysfunctional sexual beliefs and traditional sexual attitudes relative to males exposed to models of modern masculinity. Results also indicated that males exposed to traditional masculine stimuli reported lower levels of sexual inhibition due to fear of performance failure than males exposed to models of modern masculinity. The potential role of social context is discussed in the development and maintenance of male sexual dysfunction and its implications for treatment.

Sexual desire is increasingly understood to be multifaceted and not solely erotically oriented, but measures are still generally unitary and eroticism-focused. Our goals in this article were to explore the multifaceted nature of sexual desire and develop a measure to do so, and to determine how multifaceted sexual desire might be related to gender/sex and sexual orientation/identity. In the development phase, we generated items to form the 65-item Sexual Desire Questionnaire (DESQ). Next, the DESQ was administered to 609 women, 705 men, and 39 non-binary identified participants. Results showed that the DESQ demonstrated high reliability and validity, and that sexual desire was neither unitary nor entirely erotic, but instead was remarkably multifaceted. We also found that multifaceted sexual desire was in part related to social location variables such as gender/sex and sexual orientation/identity. We propose the DESQ as a measure of multifaceted sexual desire that can be used to compare factor themes, total scores, and scores across individual items in diverse groups that take social context into account. Results are discussed in light of how social location variables should be considered when making generalizations about sexual desire, and how conceptualizations of desire as multifaceted may provide important insights.

It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

Results revealed that gender issues are clearly present in participants' reports and showed to be essential in their choices about the moment, partners and contraceptive practices in the first sexual relation. Adolescents are subordinated to gender roles, traditionally attributed to male and female genders, i.e. the notion that sex is an uncontrolled instinct for boys, and intrinsically and closely associated to love and desire for girls. Adolescents also play a preponderant role in the perpetuation of these values within the group they live in.Con el objetivo de identificar las normas y expectativas sociales que se encuentran en la iniciación sexual, fueron estudiados cuatro grupos de adolescentes entre 14 y 18 años de edad, en 2.006, en la ciudad de San Pablo, Brasil.

The implications of sexual narcissism for sexual and marital satisfaction.

McNulty, James K; Widman, Laura

2013-08-01

There is theoretical reason to believe narcissism is associated with a number of sexual behaviors and outcomes that affect both sexual and relationship satisfaction. Nevertheless, research on the association between personality and behavior demonstrates that personality traits, such as narcissism, only predict behavior in domains that activate the components of the personality system. Given that global assessments of narcissism do not capture the extent to which the components of narcissism are activated in the sexual domain, we examined the extent to which the facets of a domain-specific measure of sexual narcissism accounted for the trajectories of own and partner sexual and marital satisfaction over the first five years of 120 new marriages. Three of the four facets of sexual narcissism (sexual exploitation, sexual entitlement, and low sexual empathy) were negatively associated with both trajectories. The fourth facet (sexual skill) was positively associated with both trajectories. Notably, sexual satisfaction mediated the effect of every facet of sexual narcissism on marital satisfaction. A global assessment of narcissism was not associated with either trajectory of satisfaction. These findings highlight (1) the importance of narcissistic tendencies for sexual processes, (2) the benefits of using domain-specific measures of personality in research on sexual behavior, and (3) the importance of examining the implications of the specific facets of personality constructs.

Full Text Available This paper presents the first evidence for Palaeolithic portable art in Southern Portugal. This include two plaques, dated between 20,500 and 19,500 BP from Solutrean levels from the site of Vale Boi, Western Algarve (Portugal. One of the pieces is a small engraved schist plaque (14,6 × 8,1 mm with abstract lines on one side. The other artefact is an 8 × 5 cm schist plaque. One side is an oxide natural deposit, used to produce dye; the other side has three aurochs and a probable cervid. Stilistic information and the engraving sequence indicate probably production by a single artist. The stylistic characteristics are in full agreement withi those from late Gravettian and early Solutrean art known from Valencia, Andalucia (Spain and the Côa valley (Portugal, thus confirming the absolute AMS dates from the Vale Boi Levels.

En este trabajo presentamos la primera evidencia de arte mueble paleolítico en el sur de Portugal: dos plaquetas de pizarra procedentes de niveles solutrenses del yacimiento de Vale Boi, zona occidental del Algarve (Portugal. La primera de las piezas es una pequeña placa (14,6 × 8,1 mm que presenta sobre una de sus caras un ideomorfo grabado. La segunda (8 × 5 cm cuenta con una superficie ocupada por óxido de hierro natural de color amarillento, tiene claros indicios de extracción de mineral para producir colorantes. En la superficie opuesta han sido grabados tres uros y una posible cierva. El estilo y secuencia de los grabados apuntan a un solo artista. Las características estilísticas de los zoomorfos concuerdan bien con los rasgos comunes del arte del ciclo Gravetiense final y Solutrense antiguo del País Valenciano, Andalucía y Valle de Côa (Portugal. Esta afinidad sintoniza asimismo con las fechas AMS de los niveles solutrenses de Vale Boi, datados entre ca. 20.500 y 19.500 BP.

Despite the importance of sexuality for romantic relationships, there has been little research attention to individual differences and dyadic variables, including couple similarity, and their association with sexual problems and satisfaction. The current study examined the effects of the propensity for sexual inhibition and sexual excitation scales (SIS/SES) and the effects of different mood states on sexuality (Mood and Sexuality Questionnaire [MSQ]), at both the individual and the dyad level, on sexual arousal problems and sexual satisfaction. Similarity in SIS/SES and MSQ was measured in a nonclinical sample of 35 newlywed couples and operationally defined as the within-couple, z-transformed correlations between the two partners' item responses. Sexual arousal problems were assessed using self-report measures (Demographic and Sexual History Questionnaire) and focused on the past 3 months. Sexual satisfaction was assessed using the Global Measure of Sexual Satisfaction. Regression analyses revealed that greater similarity in the effects of anxiety and stress on sexuality was associated with more reported sexual arousal problems of wives. In contrast, the husbands' sexual arousal problems were related only to their own higher SIS1 scores. Higher SES scores predicted lower sexual satisfaction for both husbands and wives. Wives who reported strong positive mood effects on their sexuality indicated greater sexual satisfaction, while husbands who were more similar to their wives in the effect of positive moods on sexuality indicated greater sexual satisfaction. The findings show that, above and beyond one's own sexual propensities, similarity in various aspects of sexuality predicts sexual problems (more so in women) and sexual satisfaction (in both men and women). © 2012 International Society for Sexual Medicine.

Sexual self-efficacy plays an important role in adolescents' sexual health. The aim of this study was to test a cause-and-effect model of sexual self-concept and sexual risk cognition toward sexual self-efficacy in adolescents. The study was a cross-sectional survey. Using a random sampling method, a total of 713 junior nursing students were invited to participate in the study, and 465 valid surveys were returned, resulting in a return rate of 65.2%. The data was collected using an anonymous mailed questionnaire. Structural equation modeling was used to test the relationships among sexual self-concept, sexual risk cognition, and sexual self-efficacy, as well as the mediating role of sexual risk cognition. The results revealed that the postulated model fits the data well. Sexual self-concept significantly predicted sexual risk cognition and sexual self-efficacy. Sexual risk cognition significantly predicted sexual self-efficacy and had a mediating effect on the relationship between sexual self-concept and sexual self-efficacy. Based on social cognitive theory and a structural equation model technique, this study confirmed the mediating role of sexual risk cognition in the relationship between sexual self-concept and sexual self-efficacy. Also, sexual self-concept's direct and indirect effects explaining adolescents' sexual self-efficacy were found in this study. © 2014 The Authors.

Morais, Hugo B; Alexander, Apryl A; Fix, Rebecca L; Burkhart, Barry R

2018-02-01

Most studies on the mental health consequences of childhood sexual abuse (CSA) focus predominantly on CSA survivors who do not commit sexual offenses. The current study examined the effects of CSA on 498 male adolescents adjudicated for sexual offenses who represent the small portion of CSA survivors who engage in sexual offenses. The prevalence of internalizing symptoms, parental attachment difficulties, specific sexual offending behaviors, and risk for sexually offending were compared among participants with and without a history of CSA. Results indicated that participants with a history of CSA were more likely to be diagnosed with major depression and posttraumatic stress disorder than those who did not report a history of CSA. A history of CSA was also positively correlated with risk for sexually offending and with specific offense patterns and consensual sexual behaviors. No significant differences emerged on parental attachment difficulties. These results highlight that adolescents adjudicated for sexual offenses with a history of CSA present with differences in sexual and psychological functioning as well as markedly different offending patterns when compared with those without a CSA history. Clinical implications and future directions are discussed.

Adolescents in sexual minority groups are known to be at risk of contracting sexually transmitted diseases through risky sexual behavior. However, few studies have examined associations between sexual orientation and risky sexual behavior and sexually transmitted diseases in Korean adolescents. Therefore, this cross-sectional study used raw data from the Tenth Korea Youth Risk Behavior Web-Based Survey to explore these relationships. Logistic regression analyses were performed to examine the associations between risky sexual behavior and sexual orientation in adolescents. The participants were 6,884 adolescents who provided data regarding demographic characteristics, sexual orientation, and risky sexual behavior. The proportions of homosexual and bisexual subjects who used condoms, engaged in sexual intercourse after drinking alcohol, and experienced sexually transmitted diseases were higher relative to those of heterosexual subjects. Associations between homosexuality and bisexuality and sexually transmitted diseases and engagement in sexual intercourse after drinking remained after multivariate adjustment. Interventions to prevent risky sexual behavior should target sexual orientation, to improve sexual health and prevent sexually transmitted disease in homosexual and bisexual adolescents.

Rethinking Sexual Citizenship.

Richardson, Diane

2017-04-01

Over the last two decades sexuality has emerged as a key theme in debates about citizenship, leading to the development of the concept of sexual citizenship. This article reviews this literature and identifies four main areas of critical framing: work that contests the significance of sexuality to citizenship; critiques that focus on the possibilities and limitations of mobilising the language of citizenship in sexual politics; analyses of sexual citizenship in relation to nationalisms and border making; and literature that critically examines western constructions of sexuality and sexual politics underpinning understandings of sexual citizenship. In order to progress the field theoretically, the article seeks to extend critiques of sexual citizenship focusing on two key aspects of its construction: the sexual citizen-subject and spaces of sexual citizenship. It argues for a critical rethink that encompasses a de-centring of a 'western-centric' focus in order to advance understandings of how sexual citizenship operates both in the Global North and South.

The relationship between sexual selection and sexual conflict.

Science.gov (United States)

Kokko, Hanna; Jennions, Michael D

2014-07-18

Evolutionary conflicts of interest arise whenever genetically different individuals interact and their routes to fitness maximization differ. Sexual selection favors traits that increase an individual's competitiveness to acquire mates and fertilizations. Sexual conflict occurs if an individual of sex A's relative fitness would increase if it had a "tool" that could alter what an individual of sex B does (including the parental genes transferred), at a cost to B's fitness. This definition clarifies several issues: Conflict is very common and, although it extends outside traits under sexual selection, sexual selection is a ready source of sexual conflict. Sexual conflict and sexual selection should not be presented as alternative explanations for trait evolution. Conflict is closely linked to the concept of a lag load, which is context-dependent and sex-specific. This makes it possible to ask if one sex can "win." We expect higher population fitness if females win. Copyright © 2014 Cold Spring Harbor Laboratory Press; all rights reserved.

The sexual cascade and the rise of pre-ejaculatory (Darwinian) sexual selection, sex roles, and sexual conflict.

Science.gov (United States)

Parker, Geoff A

2014-08-21

After brief historic overviews of sexual selection and sexual conflict, I argue that pre-ejaculatory sexual selection (the form of sexual selection discussed by Darwin) arose at a late stage in an inevitable succession of transitions flowing from the early evolution of syngamy to the evolution of copulation and sex roles. If certain conditions were met, this "sexual cascade" progressed inevitably, if not, sexual strategy remained fixed at a given stage. Prolonged evolutionary history of intense sperm competition/selection under external fertilization preceded the rise of advanced mobility, which generated pre-ejaculatory sexual selection, followed on land by internal fertilization and reduced sperm competition in the form of postcopulatory sexual selection. I develop a prospective model of the early evolution of mobility, which, as Darwin realized, was the catalyst for pre-ejaculatory sexual selection. Stages in the cascade should be regarded as consequential rather than separate phenomena and, as such, invalidate much current opposition to Darwin-Bateman sex roles. Potential for sexual conflict occurs throughout, greatly increasing later in the cascade, reaching its peak under precopulatory sexual selection when sex roles become highly differentiated.

Hypersexuality and high sexual desire: exploring the structure of problematic sexuality.

Carvalho, Joana; Štulhofer, Aleksandar; Vieira, Armando L; Jurin, Tanja

The concept of hypersexuality has been accompanied by fierce debates and conflicting conclusions about its nature. One of the central questions under the discussion is a potential overlap between hypersexuality and high sexual desire. With the relevant research in its early phase, the structure of hypersexuality remains largely unknown. The aim of the present study was to systematically explore the overlap between problematic sexuality and high sexual desire. A community online survey was carried out in Croatia in 2014. The data were first cluster analyzed (by gender) based on sexual desire, sexual activity, perceived lack of control over one's sexuality, and negative behavioral consequences. Participants in the meaningful clusters were then compared for psychosocial characteristics. To complement cluster analysis (CA), multigroup confirmatory factor analysis (CFA) of the same four constructs was carried out. Indicators representing the proposed structure of hypersexuality were included: sexual desire, frequency of sexual activity, lack of control over one's sexuality, and negative behavioral outcomes. Psychosocial characteristics such as religiosity, attitudes toward pornography, and general psychopathology were also evaluated. CA pointed to the existence of two meaningful clusters, one representing problematic sexuality, that is, lack of control over one's sexuality and negative outcomes (control/consequences cluster), and the other reflecting high sexual desire and frequent sexual activity (desire/activity cluster). Compared with the desire/activity cluster, individuals from the control/consequences cluster reported more psychopathology and were characterized by more traditional attitudes. Complementing the CA findings, CFA pointed to two distinct latent dimensions-problematic sexuality and high sexual desire/activity. Our study supports the distinctiveness of hypersexuality and high sexual desire/activity, suggesting that problematic sexuality might be more

Exploring a Contextual Model of Sexual Self-Disclosure and Sexual Satisfaction.

Brown, Randal D; Weigel, Daniel J

2018-02-01

Sexual self-disclosure is a critical component of relationship and sexual satisfaction, yet little is known about the mechanisms that facilitate a person's engagement in sexual self-disclosure. Individuals (N = 265) involved in romantic relationships participated in an online study testing a contextual model of sexual self-disclosure across three contexts: relationship context, sexual self-disclosure context, and outcome of sexual self-disclosure. Results suggest that sexual satisfaction was predicted by a positive relationship context and a positive sexual self-disclosure context. In addition, the sexual self-disclosure context was predicted by the relationship context. These findings emphasize the importance of examining contextual influences that determine whether an individual will engage in or avoid sexual self-disclosure and the consequences of this engagement or avoidance on sexual satisfaction.

People begin to become aware of their sexual drive and erotic feelings as young adolescents. Such activity often has been overlooked in Taiwan, a traditional society, because sexuality is viewed as a private issue. The purpose of this study was to explore the sexual self-concept and intended sexual behavior of young adolescent girls in Taiwan. Participants included 372 girls, 12 to 14 years old, from junior high schools in Taiwan who completed two questionnaires on sexual experience and sexually related items: the Sexual Self-Concept Inventory, the Parental Approval of Sexual Behavior Scale, and the Friends' Approval of Sexual Behavior Scale, which were combined into one scale, with separate scores. Girls' self-reports showed low (negative) sexual self-concept, high perceived parental disapproval, and somewhat high perceived friends' disapproval of sexual activities. Sexual self-concept is associated with perceived parental and peer approval of sexual activities, and it is associated with sexual experience and intended sexual activities as well. A young adolescent girl who has a high score on the perceived sexual arousability factor of the Sexual Self-Concept Inventory is more likely to report the strongest intention toward sexual behavior. Sexual self-concept may play a key role in girls' intended sexual activities, including engaging in low-level sexual activities (e.g., kissing and breast fondling) that occur before intercourse, even when associated with intercourse intention. The research suggests that addressing sexual self-concept needs to be a priority to prevent young girls from engaging in sexual intercourse.

In Ethiopia, young people with disabilities (YPWD) are often marginalized and not recognized as being sexual, and only little is known about their sexual reproductive health (SRH) status. We therefore aimed to assess the SRH status and associated factors among 426 YPWD in Addis Ababa, Ethiopia. A cross-sectional survey was conducted in 2012. Data were collected by trained interviewers using a structured questionnaire. Fifty-two percent of YPWD ever had sexual intercourse. Seventy-five percent started sex between 15 and 19 years. Only 35% had used contraceptive during their first sexual encounter. Fifty-nine percent of the sexually experienced YPWD had multiple lifetime sexual partners; 19%, a casual sexual partner; and 21%, a commercial sexual partner. Only 48% consistently used condoms with their casual or commercial sexual partners. Twenty-four percent of the sexually experienced YPWD had a history of sexually transmitted infections. Our findings indicate that YPWD in Ethiopia are sexually active, but also highly involved in risky sexual practices. There is a need for in-depth research to better understand the determinants of risky sexual behavior and to propose preventive approaches.

Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity. PMID:24215966

Sexuality and Islam.

Science.gov (United States)

Dialmy, Abdessamad

2010-06-01

This paper deals with three major questions: (1) What are the sexual norms defined by the sacred texts (Koran and Sunna)? (2) What are the sexual practices currently observed among Moslems? (3) To which extent are current sexual practices of Moslems dissociated from Islamic sexual norms? Sexual standards in Islam are paradoxical: on the one hand, they allow and actually are an enticement to the exercise of sexuality but, on the other hand, they discriminate between male and female sexuality, between marital and pre- or extramarital sexuality, and between heterosexuality and homosexuality. Men are given more rights with regard to the expression of their sexuality; women are forbidden to have extramarital sex (with their slaves) and both genders to have homosexual relationships. The combination of these paradoxical standards with modernisation leads to the current back and forth swing of sexual practices between repression and openness. Partial modernisation leads to greater sexual tolerance. But restrictive sexual standards have gathered strength and have become idealised as a result of the current radicalisation of Islam. This swing of the pendulum between repression and openness is illustrated by phenomena such as public harassment, premarital sexuality, female pleasure, prostitution, and homosexuality. Currently, Islam is not any more the only reference which provides guidance concerning sexual practices but secularisation of sexual laws is still politically unthinkable today. So the only solution is to achieve reform in the name of Islam, through the reinterpretation of repressive holy texts.

Signal trait sexual dimorphism and mutual sexual selection in Drosophila serrata.

Science.gov (United States)

Chenoweth, Stephen F; Blows, Mark W

2003-10-01

The evolution of sexual dimorphism may occur when natural and sexual selection result in different optimum trait values for males and females. Perhaps the most prominent examples of sexual dimorphism occur in sexually selected traits, for which males usually display exaggerated trait levels, while females may show reduced expression of the trait. In some species, females also exhibit secondary sexual traits that may either be a consequence of a correlated response to sexual selection on males or direct sexual selection for female secondary sexual traits. In this experiment, we simultaneously measure the intersex genetic correlations and the relative strength of sexual selection on males and females for a set of cuticular hydrocarbons in Drosophila serrata. There was significant directional sexual selection on both male and female cuticular hydrocarbons: the strength of sexual selection did not differ among the sexes but males and females preferred different cuticular hydrocarbons. In contrast with many previous studies of sexual dimorphism, intersex genetic correlations were low. The evolution of sexual dimorphism in D. serrata appears to have been achieved by sex-limited expression of traits controlled by genes on the X chromosome and is likely to be in its final stages.

Genital Appearance Dissatisfaction: Implications for Women's Genital Image Self-Consciousness, Sexual Esteem, Sexual Satisfaction, and Sexual Risk.

Schick, Vanessa R; Calabrese, Sarah K; Rima, Brandi N; Zucker, Alyssa N

Findings regarding the link between body image and sexuality have been equivocal, possibly because of the insensitivity of many of body image measures to potential variability across sensory aspects of the body (e.g., appearance versus odor), individual body parts (e.g., genitalia versus thighs), and social settings (e.g., public versus intimate). The current study refined existing methods of evaluating women's body image in the context of sexuality by focusing upon two highly specified dimensions: satisfaction with the visual appearance of the genitalia and self-consciousness about the genitalia during a sexual encounter. Genital appearance dissatisfaction, genital image self-consciousness, and multiple facets of sexuality were examined with a sample of 217 undergraduate women using an online survey. Path analysis revealed that greater dissatisfaction with genital appearance was associated with higher genital image self-consciousness during physical intimacy, which, in turn, was associated with lower sexual esteem, sexual satisfaction, and motivation to avoid risky sexual behavior. These findings underscore the detrimental impact of negative genital perceptions on young women's sexual wellbeing, which is of particular concern given their vulnerability at this stage of sexual development as well as the high rates of sexually transmitted infections within this age group. Interventions that enhance satisfaction with the natural appearance of their genitalia could facilitate the development of a healthy sexual self-concept and provide long-term benefits in terms of sexual safety and satisfaction.

Sexual concordance is defined as the association between genital response and self-reported sexual arousal. Though one might predict a strong association between sexual concordance and awareness of other internal physiological sensations (termed interoception), past research on sexually healthy women has not found these different domains to be related. The aim of the present study was to test the association between interoception and sexual concordance in a clinical sample of women with Sexual Interest/Arousal Disorder (SIAD). Fifty-two women with SIAD completed the Multidimensional Assessment of Interoceptive Awareness (MAIA), a validated self-report measure of interoception, and completed a heart-beat accuracy test, an objective measure of interoception. They also participated in a laboratory-based assessment of physiological sexual arousal and self-reported sexual arousal while viewing an erotic film. Mental and physiological arousal were correlated at r = 0.27 (range -0.80 to 0.95). There was no significant association between sexual concordance and women’s heartrate awareness. However, five aspects of interoceptive awareness (noticing, emotional awareness, self-regulation, body-listening, and trusting), were predictive of lower, and one aspect (not-distracting) was predictive of higher sexual concordance. We discuss the findings in relation to the role of emotions and arousal states in the interoception-sexual concordance relationship. PMID:29020067

Personality traits, namely neuroticism, have been suggested as vulnerability factors for the development and maintenance of sexual dysfunction in heterosexual samples. However, no evidence was found regarding homosexual samples. This study aimed to analyze the differences on personality traits between heterosexual and homosexual men and women with and without sexual problems. Participants were 285 individuals (142 men, 143 women) who completed a web-based survey. Participants answered the NEO Five-Factor Inventory, the Brief Symptomatology Inventory, and questions regarding sexual problems. The groups of men and women with and without sexual problems were matched for sociodemographic variables. A 2 (Group) × 2 (Sexual Orientation) multivariate analysis of covariance was conducted separately for each gender. Results indicated a significant main effect for group and for sexual orientation in male and female samples. Men with sexual problems scored higher on neuroticism, whereas women with sexual problems scored higher on neuroticism and lower on extraversion when compared with healthy controls, regardless of sexual orientation. In addition, gay men scored higher on neuroticism and lesbian women scored higher on conscientiousness compared with the heterosexual groups. The present findings emphasize the central role of neuroticism on sexual problems in both men and women regardless of sexual orientation.

We review the current state of sexual harassment theory, research, treatment, and prevention. Definitional problems and implications are discussed. An examination of the epidemiology of sexual harassment is presented, highlighting correlates that include characteristics of the organizational environment, the perpetrator, and the recipient of unwanted sexual behavior. Normative responses to sexual harassment and consequences are discussed. Descriptions of the most prevalent models of sexual harassment are offered and the empirical evidence for them is briefly reviewed. From there, the effect of model development and evaluation on the prevention and treatment of sexual harassment is considered. We comment on the steps that would need to be taken to develop viable prevention and treatment programs. Suggestions for fruitful avenues of research and theory development are offered.

Sexual practices in youth: analysis of lifetime sexual trajectory and last sexual intercourse

Maria Luiza Heilborn

Full Text Available This article examines the sexual practices of young Brazilians based on data from the GRAVAD Research Project, a household survey targeting males and females from 18 to 24 years of age (n = 4,634 in three Brazilian State capitals: Porto Alegre, Rio de Janeiro, and Salvador. The set of practices experienced over the course of their sexual careers is characterized by traits of social belonging, elements from individual life histories, and prescribed rules of conduct for men and women. The authors compared the young people's range of lifetime practices and those from last sexual relations in order to discuss the spread and incorporation of practices into life histories. The data point to the hegemony of vaginal sex in both the lifetime repertoire of sexual practices and the last sexual encounters, such that vaginal sex provides the prime definition of heterosexuality.

1997-04-01

Longitudinal research indicates that approximately 50% of women treated for gynecologic cancer have sexual dysfunctions as they recover and become cancer survivors. This outcome occurs in the context of satisfactory quality of life in other domains. This study, comparing gynecologic cancer survivors (n = 61) and gynecologically healthy women (n = 74), documents the reliability of the latter observations with measures of quality of life (general, depressive symptoms, social contacts, and stress), sexual functioning, and health. Of added importance are analyses focused on variables that may predict risk for sexual morbidity. Specifically, sexual self-schema is tested as an important, sexually relevant individual difference. In regression analyses that controlled for estimates of precancer sexual behavior (intercourse frequency), extent of disease-treatment, and menopausal symptoms, sexual self-schema accounted for significant variance in predicting current sexual behavior and responsiveness.

Sexual violence is a pervasive problem on university campuses. Although previous work has documented greater vulnerability for sexual violence among sexual and gender minority students, little is known about contextual variation in vulnerability to this kind of violence. The goals of the current study were (1) to identify vulnerability among sexual and gender minority students with regard to sexual violence, and (2) to explore if the context of this violence differs across sexual and gender minority status. Undergraduate students (ages 18-24) from six francophone universities in Quebec, Canada (N = 4,264) completed online questionnaires regarding their experience of sexual violence, as well as the context of these acts (e.g., the gender of the perpetrator, the status of the perpetrator, and the location of the violence). They also provided information regarding their sexual and gender minority status. Binary logistic regressions were conducted to assess for variation in experiencing sexual violence across sexual and gender minority status. Transgender/nonbinary students generally reported higher levels of sexual violence than their cisgender peers, while variation occurred with regard to vulnerability across sexual identity subgroups. Few differences in context were observed across sexual minority identity. Transgender/nonbinary students were significantly more likely to report sexual violence in athletic contexts and during volunteering activities compared to their cisgender peers. Findings highlight the higher levels of vulnerability for sexual violence among gender minority and some sexual minority university students. They also point to the contexts in which such violence occurs, suggesting specific strategies for prevention. Copyright © 2018 The Society for Adolescent Health and Medicine.

Anil Kumar Mysore Nagaraj

2009-11-01

Full Text Available Satisfying sexual experience is an essential part of a healthy and enjoyable life for most people. Antipsychotic drugs are among the various factors that affect optimal sexual functioning. Both conventional and novel antipsychotics are associated with significant sexual side effects. This review has presented various studies comparing different antipsychotic drugs. Dopamine antagonism, increased serum prolactin, serotonergic, adrenergic and cholinergic mechanisms are all proposed to be the mechanisms for sexual dysfunction. Drug treatment for this has not given satisfactory long-term results. Knowledge of the receptor pharmacology of an individual antipsychotic will help to determine whether it is more or less likely to cause sexual side effects and its management.

Sexual addictions.

Garcia, Frederico Duarte; Thibaut, Florence

The potential adverse consequences, personal distress, shame and guilt presented by patients who suffer from sexual addiction require a more in-depth understanding of the phenomenology and psychobiology of this disorder. A bibliographic review was conducted using MEDLINE and EBSCO databases with the following keywords: "sexual addiction," "hypersexuality," "compulsive sexual behavior," "behavioural addiction," "treatment," and "addiction." Several conceptualizations of excessive nonparaphilic sexual disorder have been proposed based on the models of, respectively, obsessive compulsive disorder, impulse control disorder, out of control excessive sexual disorder, and addictive disorder. Despite the lack of robust scientific data, a number of clinical elements, such as the frequent preoccupation with this type of behavior, the time spent in sexual activities, the continuation of this behavior despite its negative consequences, the repeated and unsuccessful efforts made to reduce the behavior, are in favor of an addictive disorder. In addition there is a high comorbidity between excessive sexual behavior and other addictive behaviors. The phenomenology of excessive nonparaphilic sexual disorder favors its conceptualization as an addictive behavior, rather than an obsessive-compulsive, or an impulse control disorder. Moreover, the criteria that are quite close to those of addictive disorders were recently proposed for the future DSM-V in order to improve the characterization of this condition. Finally, controlled studies are warranted in order to establish clear guidelines for treatment of sexual addiction.

Child Sexual Abuse and Negative Affect as Shared Risk Factors for Sexual Aggression and Sexual HIV Risk Behavior in Heterosexual Men.

Previous research has suggested that sexually aggressive behavior and sexual HIV risk behavior are associated. Childhood sexual abuse (CSA) is a well-established risk factor for both types of problematic sexual behavior. Negative affect (i.e., anxiety, depression, and anger) is a less well-studied risk factor, but it has been theorized to relate to both sexual aggression and HIV risk behavior. Thus, this study sought to (1) confirm the relationship between sexual aggression and HIV risk behavior, (2) establish CSA and negative affect as shared risk factors for sexual aggression and HIV risk behavior, and (3) evaluate whether negative affect mediates the relationship between CSA and sexual aggression and between CSA and HIV sexual risk in a sample of heterosexual men. We recruited 18- to 30-year-old heterosexual men (N = 377) from urban sexually transmitted infection clinics. Men completed measures of sexual HIV risk history (number of partners and condom use), sexual aggression history, CSA history, and trait negative affect (anger, anxiety, and depression). Structural equation modeling was used to examine hypothesized direct and indirect relationships. In the final SEM model, sexual aggression history and sexual HIV risk behavior were correlated. CSA was associated with both types of problematic sexual behavior. Anxiety significantly mediated the relationship between CSA and sexual aggression and between CSA and sexual HIV risk behavior (χ 2 [1300] = 2121.79, p Sexual aggression appears to be part of a constellation of sexual risk behaviors; thus, it may be possible to develop prevention programs that target both sexual HIV risk and sexual aggression. CSA is a shared risk factor for sexual aggression and HIV risk behavior through the pathway of anxiety. Thus, anxiety might be one promising target for intervention.

Se analizó la biología reproductiva de Liophis semiaureus en el nordeste de Argentina, incluyendo la madurez y dimorfismo sexual, fecundidad y ciclo reproductivo. Las hembras maduras fueron significativamente más largas, presentaron mayor peso corporal y alcanzaron la madurez sexual a una longitud mayor que los machos. Los machos tuvieron colas más largas que las hembras. El ciclo reproductivo fue estacional con mayor actividad en los períodos templados del año aunque previos a la época de inundaciones. Liophis semiaureus invirtió más energía en la reproducción que en el crecimiento, lo que posibilita que comiencen a reproducirse con tamaños más pequeños con respecto a otras poblaciones, sin retrasar su reproducción hasta alcanzar mayores tamaños. Esta puede ser una estrategia ventajosa en climas estacionales. Las características reproductivas y de dimorfismo sexual en L. semiaureus se encontrarían influenciadas por aspectos filogenéticos, geográficos y ecológicos, lo que determina que la especie responda de manera general al patrón reproductivo del grupo taxonómico pero con particularidades propias determinadas por los factores geográficos y los requerimientos ecológicos.Snakes in subtropical warm zones have a wide flexibility and diversity in your reproductive tactics.

Puberty and adolescent sexuality.

Science.gov (United States)

Fortenberry, J Dennis

2013-07-01

This article is part of a Special Issue "Puberty and Adolescence". Sexuality emerges as a major developmental element of puberty and the adolescent years that follow. However, connecting the sexuality that emerges with puberty and elements of adult sexuality is difficult because much adolescent sexuality research addresses the transition to partnered sexual behaviors (primarily coitus) and consequences such as unplanned pregnancy and sexually transmitted infections. This review proposes a framework of an expanded understanding of puberty and adolescent sexuality from the perspective of four hallmarks of adult sexuality: sexual desire; sexual arousal; sexual behaviors; and, sexual function. This approach thus addresses important gaps in understanding of the ontogeny of sex and the continuum of sexuality development from adolescence through the adult lifespan.

Endorsement and enactment of the (hetero)sexual double standard (SDS), prescribing sexual modesty for girls and sexual prowess for boys, has been shown to be negatively related to sexual and mental health. To be able to challenge the SDS, more insight is needed into the conditions that shape gendered sexual attitudes. A survey was conducted among 465 heterosexual adolescents (aged 16–20 years), examining the relationship between a number of relevant demographic and psychosexual variables and SDS endorsement. SDS endorsement was assessed using a newly developed instrument, the Scale for the Assessment of Sexual Standards Among Youth (SASSY). Gender (being male) and religiousness were significantly associated with increased SDS endorsement. For both boys and girls, increased feelings of entitlement to self-induced sexual pleasure (e.g., masturbation) were significantly associated with reduced SDS endorsement, whereas higher gender investment was significantly associated with increased SDS endorsement. Furthermore, increased feelings of entitlement to partner-induced sexual pleasure and more frequent talking about sexuality with peers were associated with increased SDS endorsement among boys but not among girls. We conclude that future research should explore peer influence processes through peer communication about sex, gender investment, and feelings of entitlement to both self and partner-induced sexual pleasure.

Friendship, sexual intimacy and young people's negotiations of sexual health.

Science.gov (United States)

Byron, Paul

2017-04-01

This paper examines how young people's friendships influence safer sexual practices. Through a thematic discourse analysis, interviews with Sydney-based young people (aged 18-25 years) and Australian-based sexual health websites for young people are considered. Interview data illustrate how friendships can support young people's sexual experiences, concerns and safeties beyond the practice of 'safe sex' (condom use). This is evident in friends' practices of sex and relationship advice, open dialogue, trust and sharing experiential knowledge, as well as friend-based sex. Meanwhile, friendship discourse from selected Australian sexual health websites fails to engage with the support offered by friendship, or its value to a sexual health agenda. Foucault's account of friendship as a space of self-invention is considered in light of these data, along with his argument that friendship poses a threat to formal systems of knowing and regulating sex. Whether sexual or not, many close friendships are sexually intimate given the knowledge, support and influence these offer to one's sexual practices and relations. This paper argues that greater attention to friendship among sexual health promoters and researchers would improve professional engagements with young people's contemporary sexual cultures, and better inform their attempts to engage young people through social media.

Meyer, Dixie; Cohn, Aaron; Robinson, Brittany; Muse, Fatima; Hughes, Rachel

2017-01-01

Child sexual abuse has the potential to cause distress for the victim across the lifespan. Romantic relationships may be particularly difficult for victims of child sexual abuse. This retrospective study examined differences in adult romantic attachment, sexually compulsive behaviors, and emotion regulation by history of child sexual abuse in a large, nonclinical sample. Those with a history of child sexual abuse reported more attachment anxiety in romantic relationships and engaged in more sexually compulsive behaviors. Overall, males displayed more sexually compulsive behaviors than females regardless of history of sexual abuse. Males with a history of sexual abuse displayed the greatest number of sexually compulsive behaviors. Surprisingly, no differences were observed in emotion regulation or attachment avoidant behaviors by history of child sexual abuse. Future research should seek to replicate current findings and examine emotion regulation difficulties experienced as a result of trauma.

Despite the World Health Organization's definition of sexual health as a state of well-being, virtually no public health research has examined sexual well-being outcomes, including sexual satisfaction. Emerging evidence suggests that sexual well-being indicators are associated with more classic measures of healthy sexual behaviors.

Many respondents reported that they were either satisfied (approximately half) or very satisfied (approximately one third). In multivariate analyses, significant (P self-comfort, self-esteem (especially among men), relationship status, and sexual frequency.

Sexual desire, not hypersexuality, is related to neurophysiological responses elicited by sexual images

Vaughn R. Steele

2013-07-01

Full Text Available Background: Modulation of sexual desires is, in some cases, necessary to avoid inappropriate or illegal sexual behavior (downregulation of sexual desire or to engage with a romantic partner (upregulation of sexual desire. Some have suggested that those who have difficulty downregulating their sexual desires be diagnosed as having a sexual “addiction”. This diagnosis is thought to be associated with sexual urges that feel out of control, high-frequency sexual behavior, consequences due to those behaviors, and poor ability to reduce those behaviors. However, such symptoms also may be better understood as a non-pathological variation of high sexual desire. Hypersexuals are thought to be relatively sexual reward sensitized, but also to have high exposure to visual sexual stimuli. Thus, the direction of neural responsivity to sexual stimuli expected was unclear. If these individuals exhibit habituation, their P300 amplitude to sexual stimuli should be diminished; if they merely have high sexual desire, their P300 amplitude to sexual stimuli should be increased. Neural responsivity to sexual stimuli in a sample of hypersexuals could differentiate these two competing explanations of symptoms. Methods: Fifty-two (13 female individuals who self-identified as having problems regulating their viewing of visual sexual stimuli viewed emotional (pleasant sexual, pleasant-non-sexual, neutral, and unpleasant photographs while electroencephalography was collected. Results: Larger P300 amplitude differences to pleasant sexual stimuli, relative to neutral stimuli, was negatively related to measures of sexual desire, but not related to measures of hypersexuality. Conclusion: Implications for understanding hypersexuality as high desire, rather than disordered, are discussed.

Full Text Available Costa Rica no sigue durante la primera década del siglo XXI la tendencia observada para la mayoría de los países de la región, que experimentan una reducción de la desigualdad en la distribución del ingreso familiar per cápita. Durante la primera mitad de esa década sí se produce una reducción en la desigualdad pero se revierte en el quinquenio siguiente. Para estudiar esos cambios se utiliza una desagregación de la desigualdad, medida por el coeficiente de Gini, por fuentes de ingreso, usando 12 fuentes distintas. Los resultados señalan que la reducción de la desigualdad en la primera mitad de la década, se da en un contexto de crecimiento económico pero estancamiento de los ingresos reales, que se concentra en los estratos de mayores ingresos. Esto implica que la reducción de la desigualdad se concentró en la reducción de los ingresos reales de las fuentes con mayor poder concentrador (elasticidades Gini ingreso mayor a la unidad y cambios marginales positivos, como lo son los ingresos laborales de los más calificados, las rentas del capital y las pensiones contributivas. En la segunda mitad de la década, el repunte de la desigualdad se produce por un aumento significativo de los ingresos reales de todas las fuentes, pero principalmente de las que tienen un impacto concentrador que no puede ser neutralizado por la expansión de las fuentes que reducen la desigualdad (ingresos laborales de los trabajadores no calificados y las transferencias estatales. Los resultados sugieren la necesidad de aplicar una política de salarios mínimos más activa, reforzar los programas de apoyo productivo para el sector informal, ampliar la oferta de trabajadores más calificados a través de la política educativa y ampliar las transferencias monetarias hacia los más pobres, lo que requiere de una reforma tributaria.

The banishment of the marvellous. Hermaphrodites and sexual mutants in Enlightenment Spain

Directory of Open Access Journals (Sweden)

Vázquez, Francisco

2011-06-01

Full Text Available This article presents a historical synthesis in order to trace how the collective belief in the existence of hermaphrodites and sex-changes was slowly eroded in the changing medical and cultural context of Enlightenment Spain. In order to explain this change, three interlinked processes are outlined. First, the naturalization of the monster and the disappearance of the “marvellous” in Enlightenment science. Second, the consolidation of modern legal or forensic science and the rise of the medical specialist as the relevant authority in the determination of sexual identity. Third, the emergence of the notion of fundamental biological differences between the sexes. The article concludes by discussing the consequences of these shifts for early nineteenthcentury Spanish medicine.

Este trabajo presenta una síntesis histórica con objeto de hacer inteligible el desgaste de la creencia colectiva en la existencia de hermafroditas y cambios de sexo, emplazando este proceso en el contexto médico y cultural de la España ilustrada. Analiza en este sentido tres procesos convergentes. En primer lugar, la naturalización del monstruo y el retiro de lo «maravilloso» en la ciencia de la Ilustración. En segundo lugar, el despegue de la Medicina legal moderna y la conversión del facultativo en la autoridad competente relacionada con la identidad sexual. Por último, se describe la tentativa de fundamentar biológicamente las diferencias entre los sexos. El trabajo concluye examinando la proyección de esta herencia intelectual ilustrada en la medicina española de las primeras décadas del siglo XIX.

Recent research on the impact of religiosity on sexuality has highlighted the role of the individual, and suggests that the effects of religious group and sexual attitudes and fantasy may be mediated through individual differences in spirituality. The present study investigated the role of religion in an ethnically diverse young adult sample (N = 1413, 69% women) using religious group as well as several religiosity domains: spirituality, intrinsic religiosity, paranormal beliefs, and fundamentalism. Differences between religious groups in conservative sexual attitudes were statistically significant but small; as predicted, spirituality mediated these effects. In contrast to the weak effects of religious group, spirituality, intrinsic religiosity, and fundamentalism were strong predictors of women’s conservative sexual attitudes; for men, intrinsic religiosity predicted sexual attitude conservatism but spirituality predicted attitudinal liberalism. For women, both religious group and religiosity domains were significant predictors of frequency of sexual fantasies while, for men, only religiosity domains were significant predictors. These results indicate that individual differences in religiosity domains were better predictors of sexual attitudes and fantasy than religious group and that these associations are moderated by gender.

Aging and sexuality.

Yee, Lesley

2010-10-01

Sexuality has become a medical issue in association with aging. This is due to a number of factors, including increasing age of survival, a positive societal construct that promotes sexuality as important for quality of life as we age, and the medicalisation of sexuality with the advent of prescription medications to treat sexual dysfunction. This article reviews the factors surrounding aging and sexuality and also considers special situations with age, such as institutionalised care and the possibility of elder abuse. Normal physiological changes with aging affect both genders in terms of sexual desire and performance. Other medical conditions increase with age, and these and their treatments will impact on sexuality and the way it can be expressed. Medical practitioners require an understanding of these changes in order to find ways to optimise sexual function in older patients.

There is limited research examining the sexual health and well-being of older women living with HIV (OWLH). Most studies focus on sexual dysfunction, leaving aside the richer context of sexuality and sexual health, including the effect of age-related psychosocial and interpersonal changes on sexual health behaviors. Guided by the integrative biopsychosocial model and the sexual health model, this study explored the importance of sex and sexuality among OWLH to identify their sexual health and HIV prevention needs for program planning. A purposive sample (n = 50) of OWLH was selected from a parent study (n = 2052). We conducted 8 focus groups and 41 in-depth interviews with 50 African American and Latina OWLH aged 50-69 years old in three U.S. cities. The triangulation approach was used to synthesize the data. Six salient themes emerged: sexual pleasure changes due to age, sexual freedom as women age, the role of relationships in sexual pleasure, changes in sexual ability and sexual health needs, sexual risk behaviors, and ageist assumptions about older women's sexuality. We found that sexual pleasure and the need for intimacy continue to be important for OWLH, but that changing sexual abilities and sexual health needs, such as the reduction of sexual desire, as well as increased painful intercourse due to menopause-associated vaginal drying, were persistent barriers to sexual fulfillment and satisfaction. Particular interpersonal dynamics, including low perceptions of the risk of HIV transmission as related to gender, viral suppression, and habitual condomless sex with long-term partners without HIV transmission have resulted in abandoning safer sex practices with serodiscordant partners. These findings suggest that HIV prevention for OWLH should focus on how sexual function and satisfaction intersect with sexual risk. HIV prevention for OWLH should promote ways to maintain satisfying and safe sex lives among aging women.

The human sexual response to sexually arousing stimuli is a motivational incentive-based cycle comprising subjective experience and physiologic changes. Clinical and empirical data support a circular model of overlapping phases of variable order. Brain imaging data of sexual arousal identify areas of cerebral activation and inhibition reflecting a complex network of cognitive, motivational, emotional, and autonomic components. Psychologic and biologic factors influence the brain's appraisal and processing of sexual stimuli to allow or disallow subsequent arousal. The sexual and non-sexual outcomes influence motivation to future sexual intimacy. Variability is marked both between individuals and within a person's sexual life, influenced by multiple factors, including stage of life cycle, mental health, and relationship happiness. Neurologic disease can interrupt the cycle at many points: by limiting motivation, reducing ability to attend to and feel sexual stimuli, and accomplishing the movements needed to stimulate and experience intercourse. Impairments to genital congestion, penile erection, and orgasm may also occur. Disease-associated changes to the interpersonal relationship and self-image plus frequently comorbid depression will tend to lessen motivation and temper the brain's appraisal of sexual stimuli, so precluding arousal. Therapy begins by explaining the sexual response cycle, clarifying the points of interruption in the patient's own cycle so as to guide treatment. © 2015 Elsevier B.V. All rights reserved.

The electric rays obtained were separate by sex, weighed and measured; the development of reproductive stage was identified by external and internal characteristics. The reproductive condition was determinate by (gonadosomatic GSI and hepatosomatic HSI indexes and the size at sexual maturity (l50%. The results showed that the GSI has one peak at year between September and December when probably the copulation carried out, the HSI presented its highest value in January, which corresponds to the end of the reproductive period. The size at sexual maturity was 32.2 cm in females and it was between 20.2 and 22.9 cm in males.

Although it is known that women with dyspareunia suffer from impaired psychological and sexual functioning, the study of the various dimensions of sexual self-schema and their associations with these outcomes has been neglected. To examine whether self-image cognitions about vaginal penetration, body image, and feelings and beliefs about one's own genitals contribute to the variance in pain, sexual functioning, and sexual distress. Premenopausal women (n = 231; M age = 24.85, SD = 5.55) with self-reported dyspareunia completed an online survey focusing on self-image cognitions about vaginal penetration, body image, female genital self-image, pain during intercourse, sexual functioning, sexual distress, anxiety, and catastrophizing. (i) Pain intensity during intercourse, (ii) the Female Sexual Function Index without the Pain subscale, and (iii) the Female Sexual Distress Scale. Controlling for anxiety and catastrophizing, negative self-image cognitions about vaginal penetration, negative body image, and negative genital self-image together accounted for a portion of the variance in increased pain intensity, sexual dysfunction, and sexual distress. However, only self-image cognitions about vaginal penetration (β = 0.25, P = 0.005) contributed uniquely to the variance in pain intensity, whereas self-image cognitions about vaginal penetration (β = -0.18, P = 0.048) and genital self-image (β = 0.21, P = 0.008) contributed independently to the variance in sexual functioning. Finally, self-image cognitions about vaginal penetration (β = 0.28, P < 0.001), body image (β = 0.24, P < 0.001) and genital self-image (β = -0.14, P = 0.006) each contributed independently to the variance in sexual distress. Findings suggest that self-image cognitions about vaginal penetration and feelings and beliefs about one's own body and genitals are associated with pain and sexuality outcomes in women with dyspareunia. © 2013

Purpose To determine factors associated with students’ comfort in addressing patients’ sexuality in the clinical context. Method The authors invited students enrolled in MD-degree-granting and osteopathic medical schools in the United States and Canada to participate in an anonymous Internet survey between February and July 2008. The survey assessed ethnodemographic factors and sexual history. Respondents also completed the Center for Epidemiologic Studies Depression Scale. Male respondents completed the International Index of Erectile Function and the Premature Ejaculation Diagnostic Tool. Female respondents completed the Female Sexual Function Index and the Index of Sex Life. The authors used descriptive statistics, ANOVA, and multivariable logistic regression to analyze responses. Results The authors’ analyses included 2,261 completed survey responses: 910 from men, 1,343 from women, and 8 from individuals who self-identified as “other” gendered. Over 53% of respondents (n = 1,206) stated that they felt they had not received sufficient training in medical school to address sexual concerns clinically. Despite this, 81% of students (n = 1,827) reported feeling comfortable dealing with their patients’ sexuality issues. Students with limited sexual experience, students at risk for sexual problems, and students who felt that they had not been trained adequately were less likely to report being comfortable talking to patients about sexual health issues. Conclusions Perception of inadequate sexuality training in medical school and personal issues pertaining to sex may be associated with students’ difficulty in addressing patients’ sexuality. Adequate training is preeminently associated with feeling comfortable addressing patients’ sexuality and should be a priority for medical education. PMID:20671459

Military sexual trauma (MST) includes sexual harassment or sexual assault that occurs during military service and is of increasing public health concern. The population prevalence of MST among female and male veterans who served during Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) has not been estimated to our knowledge. The purpose of this study is to assess the population prevalence and identify military correlates of MST, sexual harassment, and sexual assault among OEF/OIF veterans. MST was assessed in the 2009-2011 National Health Study for a New Generation of U.S. Veterans, a survey of 60,000 veterans who served during the OEF/OIF eras (response rate, 34%, n=20,563). Weighted prevalence estimates and AORs of MST, sexual harassment, and sexual assault among women and men were calculated. Gender-stratified logistic regression models controlled for military and demographic characteristics. Data analyses were conducted in 2013-2014. Approximately 41% of women and 4% of men reported experiencing MST. Deployed men had lower risk for MST compared with non-deployed men, though no difference was found among women. However, veterans reporting combat exposure during deployment had increased risk for MST compared with those without, while controlling for OEF/OIF deployment. Among women, Marines and Navy veterans had increased risk for MST compared with Air Force veterans. MST was significantly higher among veterans who reported using Veterans Affairs healthcare services. These prevalence estimates underscore the importance of public awareness and continued investigation of the public health impact of MST. Published by Elsevier Inc.

This study was conducted to test interpersonal, attitudinal, and sexual predictors of sexual assertiveness in a Spanish sample of 1,619 men and 1,755 women aged 18-87 years. Participants completed measures of sexual assertiveness, solitary and dyadic sexual desire, sexual arousal, erectile function, sexual attitudes, and frequency of partner abuse. In men, higher sexual assertiveness was predicted by less non-physical abuse, more positive attitudes toward sexual fantasies and erotophilia, higher dyadic desire, and higher sexual arousal. In women, higher sexual assertiveness was predicted by less non-physical abuse, less solitary sexual desire and higher dyadic sexual desire, arousal, erotophilia, and positive attitudes towards sexual fantasies. Results were discussed in the light of prevention and educational programs that include training in sexual assertiveness skills.

Lindgren, Kristen P; Schacht, Rebecca L; Mullins, Peter M; Blayney, Jessica A

This research evaluated the association between gender and sexual debut (initial sexual intercourse) and indirect measures of sexuality. A sample of 440 U.S. college students (pre-sexual debut: 144 women, 153 men; post-sexual debut: 49 women, 94 men) completed the Sexual Self-Schema Scale (SSSS), which assessed cognitive representations about sexual aspects of oneself, and three Implicit Association Tests (IAT), which measured the strength of the associations between the concepts of self + sex, women + sex, and men + sex. Results replicated previous findings that (1) men more strongly associated self + sex and women + sex than did women, and (2) men and women had similarly strong associations of men + sex. Post-sexual debut women's self + sexual and women + sexual associations were stronger than pre-sexual debut women's. Men's associations did not differ significantly as a function of sexual debut. Post-sexual debut women's SSSS scores were more direct, more romantic, and less conservative than pre-sexual debut women's. Post-sexual debut men's SSSS scores were more aggressive and more open-minded than pre-sexual debut men's. Sexual debut appeared to be associated with sexualized and sexually liberal cognitive representations in women and, to a lesser extent, sexually liberal and aggressive cognitive representations in men. Findings were consistent with theories of cognitive consistency and provide preliminary evidence that sexual debut status was associated with differing cognitive representations.

Deconstructing sexual orientation: understanding the phenomena of sexual orientation.

Science.gov (United States)

Stein, T S

1997-01-01

The very terms of a debate about whether or not sexual orientation is primarily a biological phenomenon fail to consider the complex origins of the phenomenon. Deconstruction of the term "homosexuality" shows that it refers to multiple factors which cannot be studied as or subsumed under a unitary concept. Adequate understanding of sexual orientation must consider the developmental, interpersonal, experiential, and cultural dimensions of sexuality, as well as any biological contributions to sexual attraction, behavior, and identity.

Relating sexual sadism and psychopathy to one another, non-sexual violence, and sexual crime behaviors.

Robertson, Carrie A; Knight, Raymond A

Sexual sadism and psychopathy have been theoretically, clinically, and empirically linked to violence. Although both constructs are linked to predatory violence, few studies have sought to explore the covariation of the two constructs, and even fewer have sought to conceptualize the similarities of violence prediction in each. The current study considered all four Psychopathy Checklist-Revised (PCL-R) facets and employed well-defined, validated measures of sadism to elucidate the relation between sadism and psychopathy, as well as to determine the role of each in the prediction of non-sexual violence and sexual crime behaviors. Study 1 assessed 314 adult, male sex offenders using archival ratings, as well as the self-report Multidimensional Inventory of Development, Sex, and Aggression (the MIDSA). Study 2 used archival ratings to assess 599 adult, male sex offenders. Exploratory and confirmatory factor analyses of crime scene descriptions yielded four sexual crime behavior factors: Violence, Physical Control, Sexual Behavior, and Paraphilic. Sadism and psychopathy covaried, but were not coextensive; sadism correlated with Total PCL-R, Facet 1, and Facet 4 scores. The constructs predicted all non-sexual violence measures, but predicted different sexual crime behavior factors. The PCL-R facets collectively predicted the Violence and Paraphilic factors, whereas sadism only predicted the Violence factor. © 2013 Wiley Periodicals, Inc.

Childhood Sexual Abuse

Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

College Sexual Assault and Campus Climate for Sexual- and Gender-Minority Undergraduate Students.

Coulter, Robert W S; Rankin, Susan R

2017-03-01

Sexual- and gender-minority (e.g., lesbian, gay, bisexual, and transgender) undergraduate students are at greater risk for sexual assault victimization than their cisgender (i.e., nontransgender) heterosexual peers. However, few studies have examined how social environments affect sexual assault victimization among sexual- and gender-minority undergraduate students. Nevertheless, this research area was identified as a priority by the Institute of Medicine as well as President Barack Obama's White House Task Force to Protect Students From Sexual Assault. Therefore, we tested the association between college campuses' inclusion of sexual- and gender-minority people and experiences of sexual assault victimization. Cross-sectional surveys were completed by sexual- and gender-minority undergraduate students ( N = 1,925) from higher education institutions in all 50 U.S. states in 2010. Our dependent variable was experiencing sexual assault victimization at college. Our primary independent variable was campus climate, measured with items assessing perceived inclusion of sexual- and gender-minority people and witnessing sexual- or gender-minority harassment. We used multivariable logistic regression with generalized estimating equations (accounting for the clustering of students within schools) to estimate the association between campus climate and experiencing sexual assault victimization. Overall, 5.2% of the sample reported ever being victims of sexual assault at college. Controlling for sexual orientation, gender identity, race/ethnicity, and year in school, greater perceived inclusion of sexual- and gender-minority people on campus was associated with significantly lower odds of experiencing sexual assault victimization. Our study suggests that improving campus climate for sexual- and gender-minority individuals may reduce their prevalence of college sexual assault, which has potential implications for college practitioners and administrators as well as sexual assault

La televisión colombiana y elmanejo de la orientación sexual no convencional

Full Text Available Desde que iniciaron las transmisiones para televisión en Colombia (junio 13 de 1954, éstas representaron, como en otros países, una oportunidad y a la vez un reto para la información y la educación de toda la población en diferentes áreas del conocimiento1. Sin embargo, hace más de medio siglo no se pensó el rol protagónico que se asumiría la televisión en la propuesta de valores y modelos a seguir, en particular, en comportamiento sexual de los adolescentes2. Sin duda, el manejo de los temas relacionados con sexualidad, implícita y explícita, en la televisión colombiana evolucionó como lo hizo la sociedad o la comunidad misma desde las primeras novelas que se emitieron en 1963 en las que se recreaba, y era de esperar, el modelo heterosexual de pareja hasta algunas producciones actuales que presentan de manera muy tímida otros modelos de parejas no convencionales, no heterosexuales1,3.

Despite a growing number of female same-gender (FSG) relationships, couples-based research and interventions have focused primarily on mixed-gender couples. Consequently, research has applied a heteronormative lens to understanding some relationship factors, including sexuality. The current study sought to provide descriptive data regarding frequency and conceptualizations of sex across partners in FSG relationships, as well as to analyze how relationship factors are associated with sexual satisfaction in this population. Participants (N = 206) were 103 adult FSG couples who had been together for at least 2 months. Individuals provided self-report data on how they conceptualized sex, and actor-partner models were utilized to assess relationship factors associated with sexual satisfaction. Findings indicated that women in FSG relationships hold broad definitions of sex, with the majority of behaviors conceptualized as sex, including acts that involved partnered genital touching. In dyadic actor-partner models, sexual satisfaction was predicted by several factors including sexual frequency, emotional intimacy, and sexual intimacy. Unexpectedly, higher desired sexual frequency was associated with lower sexual satisfaction; however, this finding only emerged after controlling for actual sexual frequency, suggesting that discrepancies between desired and actual sex frequency may be important for FSG couples. Implications for clinical practice with FSG couples are explored, including a strength-based focus on broad conceptualizations of sex within this population and targeting relationship factors associated with sexual satisfaction.

To assess the importance of sex and the prevalence of sexual dysfunction among middle-aged and older adults throughout the world. Increasing life expectancy has been accompanied by improvements in the health of the middle-aged and elderly, but little is known about how this has affected their sexual experience. Data were collected in 29 countries from 27,500 men and women aged 40 to 80 years using a standardized questionnaire (self-completed or by interview). Sexual dysfunction was defined as frequent and persistent problems. They included early ejaculation and erectile difficulties in men, lubrication difficulties and pain during intercourse in women, and a lack of sexual interest, an inability to achieve orgasm, and a feeling of unpleasurable sex in both. More than 80% of the men and 65% of the women had had sexual intercourse during the past year. Of these subjects, the most common dysfunctions were early ejaculation (14%) and erectile difficulties (10%) among the men and a lack of sexual interest (21%), inability to reach orgasm (16%), and lubrication difficulties (16%) among the women. Overall, 28% of the men and 39% of the women said that they were affected by at least one sexual dysfunction. The results of our study indicate that sexual desire and activity are widespread among middle-aged and elderly men and women worldwide and persist into old age. The prevalence of sexual dysfunctions was quite high and tended to increase with age, especially in men. Although major between-country differences were noted, this global study revealed some clear and consistent patterns.

2012-01-01

In response to the very limited and mostly outdated literature on older lesbian sexuality, this exploratory study examined older lesbian sexual identity, romantic relationships, the impact of aging, and experiences of discrimination within these contexts. Utilizing an online survey that recruited via numerous online lesbian communities and snowball sampling, 456 lesbians over the age of 50 responded to closed, Likert scale, and open-ended questions that provided a preliminary understanding of older lesbian sexuality. The results indicated that older lesbians have experienced fluidity in past romantic and sexual relationships, as well as in erotic fantasies, despite strong identification with being lesbian. The findings also indicate a decreased focus on sexuality in the context of relationships, with more focus on stability and continuity. Future research is needed that provides greater specificity and detail about older lesbian conceptions of sexual behavior and sexual identity labels, as well as specific sexual behaviors.

Sexting (sending/receiving sexually explicit texts and images via cell phone) may be associated with sexual health consequences among adolescents. However, to date, no published data from a probability-based sample has examined associations between sexting and sexual activity. A probability sample of 1839 students was collected alongside the 2011 Youth Risk Behavior Survey in Los Angeles high schools. Logistic regressions were used to assess the correlates of sexting behavior and associations between sexting and sexual risk-taking. Fifteen percent of adolescents with cell phone access reported sexting, and 54% reported knowing someone who had sent a sext. Adolescents whose peers sexted were more likely to sext themselves (odds ratio [OR] = 16.87, 95% confidence interval [CI]: 9.62-29.59). Adolescents who themselves sexted were more likely to report being sexually active (OR = 7.17, 95% CI: 5.01-10.25). Nonheterosexual students were more likely to report sexting (OR = 2.74, 95% CI: 1.86-4.04), sexual activity (OR = 1.52, 95% CI: 1.07-2.15), and unprotected sex at last sexual encounter (OR = 1.84, 95% CI: 1.17-2.89). Sexting, rather than functioning as an alternative to "real world" sexual risk behavior, appears to be part of a cluster of risky sexual behaviors among adolescents. We recommend that clinicians discuss sexting as an adolescent-friendly way of engaging patients in conversations about sexual activity, prevention of sexually transmitted infections, and unwanted pregnancy. We further recommend that discussion about sexting and its associated risk behavior be included in school-based sexual health curricula.

Sexual pain is an underrecognized and poorly treated constellation of disorders that significantly impact affected women and their partners. Recognized as a form of chronic pain, sexual pain disorders are heterogeneous and include dyspareunia (superficial and deep), vaginismus, vulvodynia, vestibulitis, and noncoital sexual pain disorder. Women too often tolerate pain in the belief that this will meet their partners' needs. This article provides a review of the terminology and definition of the condition, theories on the pathophysiology, diagnostic considerations, and recommendations on the management of female sexual pain.

Full Text Available Abstract Background The association between risky sexual behaviours and substance uses among Ghanaian youth were investigated. Methods An in-school cross-sectional representative survey was conducted among 12-18-year- old youth in Ghana in 2008 (N = 1195, response rate =90%. Logistic regression analyses were employed to investigate the association between substance use (tobacco use, drunkenness, marijuana use and other drug uses and risky sexual behaviours (sexual debut, condom use and number of sexual partners. Results Of all youth, 25% (28% boys and 23% girls were sexually experienced. The mean age for first sexual intercourse was 14.8 years (14.4 years for boys and 15.1 years for girls. Among the sexually experienced, 31% had multiple sexual partners. Older age (OR = 3.4, 95% CI = 1.7-3.4 and rural residency (OR = 1.5, 95% CI = 1.1-2.1 were independently associated with sexual debut while only older age (OR = 2.4, 95% CI = 1.7-3.4 was associated with condom use. Additionally, smoking (OR = 3.7, 95% CI = 2.0-6.8, tawa use (OR = 2.4, 95% CI = 1.3-4.7, tobacco use (OR = 2.8, 95% CI = 1.7-4.7 drunkenness (OR = 1.7, 95% CI = 1.1-2.8 and marijuana use (OR = 3.3, 95% CI = 1.6-7.0 were independently associated with sexual debut. Furthermore, all substance uses studied were associated with having one or multiple sexual partners. Conclusion Substance use seems to be a gateway for risky sexual behaviours among Ghanaian youth. Public health interventions should take into account the likelihood of substance use among sexually experienced youth.

There is limited research examining the sexual health and wellbeing of older women living with HIV (OWLH). Most studies focus on sexual dysfunction, leaving aside the richer context of sexuality and sexual health, including the effect of age-related psychosocial and interpersonal changes on sexual health behaviors. Guided by the integrative biopsychosocial model and the sexual health model, this study explored the importance of sex and sexuality among OWLH to identify their sexual health and HIV prevention needs for program planning. A purposive sample (n=50) of OWLH was selected from a parent study (n=2,052). We conducted 8 focus groups and 41 in-depth interviews with 50 African American and Latina OWLH aged 50–69 years old in three U.S. cities. The triangulation approach was used to synthesize the data. Six salient themes emerged: sexual pleasure changes due to age, sexual freedom as women age, the role of relationships in sexual pleasure, changes in sexual ability and sexual health needs, sexual risk behaviors, and ageist assumptions about older women’s sexuality. We found that sexual pleasure and the need for intimacy continue to be important for OWLH, but that changing sexual abilities and sexual health needs, such as the reduction of sexual desire, as well as increased painful intercourse due to menopause-associated vaginal drying, were persistent barriers to sexual fulfillment and satisfaction. Particular interpersonal dynamics, including low perceptions of the risk of HIV transmission as related to gender, viral suppression and habitual condomless sex with long term partners without HIV transmission have resulted in abandoning safer sex practices with serodiscordant partners. These findings suggest that HIV prevention for OWLH should focus on how sexual function and satisfaction intersect with sexual risk. HIV prevention for OWLH should promote ways to maintain satisfying and safe sex lives among aging women. PMID:27220311

Full Text Available Background: It is widely agreed upon that gender is a key aspect of sexuality however, questions remain on how gender exactly influences adolescents’ sexual health. Objective: The aim of this research was to study correlations between gender equality attitudes and sexual behavior, sexual experiences and communication about sex among sexually active and non-sexually active adolescents in 2 Latin American countries. Design: In 2011, a cross-sectional study was carried out among 5,913 adolescents aged 14–18 in 20 secondary schools in Cochabamba (Bolivia and 6 secondary schools in Cuenca (Ecuador. Models were built using logistic regressions to assess the predictive value of attitudes toward gender equality on adolescents’ sexual behavior, on experiences and on communication. Results: The analysis shows that sexually active adolescents who consider gender equality as important report higher current use of contraceptives within the couple. They are more likely to describe their last sexual intercourse as a positive experience and consider it easier to talk with their partner about sexuality than sexually experienced adolescents who are less positively inclined toward gender equality. These correlations remained consistent whether the respondent was a boy or a girl. Non-sexually active adolescents, who consider gender equality to be important, are more likely to think that sexual intercourse is a positive experience. They consider it less necessary to have sexual intercourse to maintain a relationship and find it easier to communicate with their girlfriend or boyfriend than sexually non-active adolescents who consider gender equality to be less important. Comparable results were found for boys and girls. Conclusions: Our results suggest that gender equality attitudes have a positive impact on adolescents’ sexual and reproductive health (SRH and wellbeing.

In a study of 142 couples, we gathered survey data to show how sexual communication influences sexual and relationship satisfaction as well as sexual and orgasm frequency. In two dyadic data path analyses, we observed the significant paths of influence that sexual communication has on sexual and relationship satisfaction, as well as sexual and orgasm frequency. Our findings revealed greater amounts of sexual communication were associated with increased orgasm frequency in women and greater relationship and sexual satisfaction in both sexes. We also observed important differences in the associations of sexual communication and general communication on satisfaction levels. With these analyses, we expand the current literature to broaden our understanding of the role that sexual communication plays in committed relationships. © 2017 American Association for Marriage and Family Therapy.

Studies have linked obesity, a sedentary lifestyle, and tobacco smoking to erectile dysfunction, but the evidence linking unhealthy lifestyle factors to other sexual dysfunctions or to sexual inactivity is conflicting. To examine associations between unhealthy lifestyle factors and sexual inactivity with a partner and four specific sexual dysfunctions in each sex. We used nationally representative survey data from 5,552 Danish men and women aged 16-97 years in 2005. Cross-sectional associations of lifestyle factors with sexual inactivity and sexual dysfunctions were estimated by logistic regression-derived, confounder-adjusted odds ratios (ORs). We calculated ORs for sexual inactivity with a partner and for sexual dysfunction and sexual difficulties overall in both sexes, for erectile dysfunction, anorgasmia, premature ejaculation, and dyspareunia in men, and for lubrication insufficiency, anorgasmia, dyspareunia, and vaginismus in women. Obesity (body mass index [BMI]≥30 kg/m(2) ) or a substantially increased waist circumference (men ≥102 cm; women ≥88 cm), physical inactivity, and, among women, tobacco smoking were each significantly associated with sexual inactivity in the last year. Among sexually active men, both underweight (BMI 21 alcoholic beverages/week), tobacco smoking, and use of hard drugs were each significantly positively associated with one or more sexual dysfunctions (ORs between 1.71 and 22.0). Among sexually active women, the only significant positive association between an unhealthy lifestyle factor and sexual dysfunction was between hashish use and anorgasmia (OR 2.85). In both sexes, several unhealthy lifestyle factors were associated with sexual inactivity with a partner in the last year. Additionally, among sexually active participants, men with unhealthy lifestyles were significantly more likely to experience sexual dysfunctions. Considering the importance of a good sex life, our findings may be useful in attempts to promote healthier

CONCLUSIONS: Sexting, rather than functioning as an alternative to “real world” sexual risk behavior, appears to be part of a cluster of risky sexual behaviors among adolescents. We recommend that clinicians discuss sexting as an adolescent-friendly way of engaging patients in conversations about sexual activity, prevention of sexually transmitted infections, and unwanted pregnancy. We further recommend that discussion about sexting and its associated risk behavior be included in school-based sexual health curricula. PMID:22987882

This article examines (a) variation in rates of sexual harassment across mode (e.g., in-person, online) and type of harassment, (b) the impact of sexual harassment (i.e., distressing vs. non-distressing), and (c) how sexual harassment is similarly and differently experienced across sexual orientation and gender identity groups. Data were collected as part of the Teen Health and Technology online survey of 5,907 13 to 18 year-old Internet users in the United States. Past year sexual harassment was reported by 23-72% of youth, depending upon sexual orientation, with the highest rates reported by lesbian/queer girls (72%), bisexual girls (66%), and gay/queer boys (66%). When examined by gender identity, transgender youth reported the highest rates of sexual harassment - 81%. Overall, the most common modes for sexual harassment were in-person followed by online. Distress in the form of interference with school, family, and/or friends; creating a hostile environment; or being very/extremely upset was reported by about half of the sexually harassed bisexual girls and lesbian/queer girls, 65% of the gender non-conforming/other gender youth, and 63% of the transgender youth. Youth with high social support and self-esteem were less likely to report sexual harassment. Findings point to the great importance of sexual harassment prevention for all adolescents, with particular emphasis on the unique needs and experiences of youth of different sexual orientations and gender identities. Socio-emotional programs that emphasize self-esteem building could be particularly beneficial for reducing the likelihood of victimization and lessen the impact when it occurs.

Provoked vestibulodynia (PVD) is the most frequent subtype of vulvodynia. Women report negative consequences of PVD on their sexual and romantic relationships. Researchers have recently highlighted the importance of examining interpersonal factors such as intimacy, and of including both women and their partners in study designs. The aim of this study was to investigate sexual and relationship intimacy as defined by the Interpersonal Process Model of Intimacy and their associations with sexual satisfaction, sexual function, pain self-efficacy, and pain intensity among women with PVD and their partners. Ninety-one heterosexual women (M age = 27.38, SD = 6.04) diagnosed with PVD and their partners (M age = 29.37, SD = 7.79) completed measures of sexual and relationship intimacy, sexual satisfaction, sexual function, pain self-efficacy, and pain intensity. Dependent measures were the (i) Global Measure of Sexual Satisfaction Scale; (ii) Female Sexual Function Index; (iii) Painful Intercourse Self-Efficacy Scale; and (iv) visual analog scale of pain intensity during intercourse. After controlling for women's age, women's greater sexual intimacy (β = 0.49, P sexual satisfaction and higher pain self-efficacy (β = 0.39, P = 0.001), beyond the effects of partners' sexual intimacy. Also, women's greater sexual intimacy (β = 0.24, P = 0.05) and women's greater relationship intimacy (β = 0.54, P = 0.003) were associated with greater women's sexual function, beyond the effects of partners' sexual and relationship intimacy. Women's self-reported sexual and relationship intimacy in the couple relationship may promote higher sexual satisfaction, sexual function, and pain self-efficacy, as well as possibly foster greater sexual well-being among women with PVD. The authors discuss implications for the inclusion of emotional and interpersonal aspects of the couple's dynamic in clinical interventions and future research in PVD. © 2013

This study explores the relationship of sexual abuse during childhood and adolescence with HIV-related sexual risk behaviors during adulthood among female sexual partners of injection drug users. It analyzed data that was gathered between 1990 and 1993, which included a sample of 2794 women from the US, Mexico, and Puerto Rico. 6 HIV-related sexual risk behaviors that occurred during the month prior to interview were examined; namely, number of sexual partners, number of drug-injecting sexual partners, number of sexual intercourse while high on alcohol and/or other drugs, number of times trading sex for drugs and/or money, proportion of all sexual acts involving protection, and overall HIV-related sexual risk. The results showed that more than one-third of the women (36.3%) experienced some form of sexual abuse during childhood, whereas 34.4% reported that they had been abused sexually during adolescence; 1 in 5 women (18.4%) stated being abused during both periods. The results further indicate that there is a strong link between sexual abuse victimization early in life and involvement later in life in HIV-related sexual risk behaviors. It was found out that certain forms of sexual abuse, such as forced exposure and touching of one's sexual parts were more strongly related than other forms of sexual abuse to subsequent involvement in HIV-related sexual behaviors.

Men's sexual self-schema.

Andersen, B L; Cyranowski, J M; Espindle, D

Sexual self-schemas are cognitive generalizations about sexual aspects of oneself. In Part 1, a measure of men's sexual self-schema is developed. Studies of test-retest and internal consistency reliability and validity studies of factor analysis, internal structure, convergent and discriminant validity, process, group difference, and change are provided. The construct consists of 3 dimensions: passionate-loving, powerful-aggressive, and open-minded-liberal traits. In Part 2, the data suggest that men's sexual schema is derived from past sexual experience, is manifest in current sexual experience, and guides future sexual behavior. In Part 3, the data document the cognitive processing aspects of sexual schema. Consistent with the investigators' schema research with women, these data substantiate the importance of cognitive representations of sexuality.

Syndemics, or the co-occurrence and interaction of health problems, have been examined extensively among young men who have sex with men, but their existence remain unexamined, to our knowledge, among sexual-minority (i.e., lesbian, gay, and bisexual) women. Thus, we investigated if syndemics were present among young sexual-minority women, and if sexual-orientation discrimination was an independent variable of syndemic production. A total of 467 sexual-minority women between the ages of 18 and 24 completed a cross-sectional online survey regarding their substance use, mental health, sexual behaviors, height, weight, and experiences of discrimination. We used structural equation modeling to investigate the presence of syndemics and their relationship to sexual-orientation discrimination. Heavy episodic drinking, marijuana use, ecstasy use, hallucinogen use, depressive symptoms, multiple sexual partners, and history of sexually transmitted infections (STIs) comprised syndemics in this population (chi-square=24.989, P=.201; comparative fit index [CFI]=0.946; root mean square error of approximation [RMSEA]=0.023). Sexual-orientation discrimination is significantly and positively associated with the latent syndemic variable (unstandardized coefficient=0.095, Pdiscrimination (unstandardized coefficient=0.602, P>.05). Syndemics appear to be present and associated with sexual-orientation discrimination among young sexual-minority women. Interventions aimed at reducing discrimination or increasing healthy coping may help reduce substance use, depressive symptoms, and sexual risk behaviors in this population.

Sexual harassment and prior sexual trauma among African-American and white American women.

Wyatt, G E; Riederle, M

1994-01-01

This study examined the relationship between sexual harassment in work, educational, and social settings and sexual abuse in childhood and/or adulthood in a stratified community sample of 248 African-American and white American women. The cumulative impact of sexual victimization on women's sense of general well-being was also examined. Those most likely to be sexually harassed in work and social settings were women with contact sexual abuse histories, regardless of ethnicity. The work status of harassers of women with sexual abuse histories differed significantly by ethnic group. Although women with prior sexual abuse experiences from both ethnic groups most frequently reported a response to sexual harassment at work, they least frequently did so in social settings. A history of childhood sexual abuse was more negatively associated with African- American women's well-being than were repeated experiences of sexual violence. Future research should address the implications of ethnic and cultural issues on the cumulative impact of incidents of sexual violence on women of color.

Emotions during sexual activity: differences between sexually functional and dysfunctional men and women.

The present study investigated the differences in emotional response to automatic thoughts presented during sexual activity between sexually functional and dysfunctional men and women. A total of 376 participants (160 women and 120 men without sexual problems and 47 women and 49 men with a DSM-IV-TR diagnosis of sexual dysfunction) completed the Sexual Modes Questionnaire (SMQ male and female versions; P. J. Nobre & J. Pinto-Gouveia, 2000) and measures of sexual functioning: The International Index of Sexual Function (IIEF; R. C. Rosen et al., 1997), and The Female Sexual Function Index (FSFI; R. C. Rosen et al., 2000). The SMQ is a combined measure constituted by three interdependent subscales: Automatic Thought subscale (AT), Emotional Response subscale (ER), and Sexual Response subscale (SR). Emotions were assessed by the ER subscale, where participants endorsed emotional reactions (worry, sadness, disillusion, fear, guilt, shame, anger, hurt, pleasure, satisfaction) to a list of automatic thoughts (AT subscale) that may occur during sexual activity. Results showed that both men and women with sexual dysfunction had significantly less positive emotional reactions to automatic thoughts during sexual activity. Sexually dysfunctional men had significantly more emotions of sadness, disillusion, and fear, and less pleasure and satisfaction, compared to men without sexual problems. Women with sexual dysfunction had significantly less pleasure and satisfaction, and more sadness, disillusion, guilt, and anger. Findings were congruent with recent studies indicating that emotions related to depressed affect (sadness, disillusion, lack of pleasure) as opposed to negative emotions (mostly related to anxiety) were stronger correlates of sexual dysfunction.

Objectives. We compared the likelihood of childhood sexual abuse (under age 18), parental physical abuse, and peer victimization based on sexual orientation. Methods. We conducted a meta-analysis of adolescent school-based studies that compared the likelihood of childhood abuse among sexual minorities vs sexual nonminorities. Results. Sexual minority individuals were on average 3.8, 1.2, 1.7, and 2.4 times more likely to experience sexual abuse, parental physical abuse, or assault at school or to miss school through fear, respectively. Moderation analysis showed that disparities between sexual minority and sexual nonminority individuals were larger for (1) males than females for sexual abuse, (2) females than males for assault at school, and (3) bisexual than gay and lesbian for both parental physical abuse and missing school through fear. Disparities did not change between the 1990s and the 2000s. Conclusions. The higher rates of abuse experienced by sexual minority youths may be one of the driving mechanisms underlying higher rates of mental health problems, substance use, risky sexual behavior, and HIV reported by sexual minority adults.

Sexuality, culture and society: shifting paradigms in sexuality research.

Science.gov (United States)

Parker, Richard

2009-04-01

Over the course of the past three decades, there has been a significant increase of research on the social and cultural dimensions of sexuality. This paper reviews three major phases in the development of this work. In the first phase, work focusing on the social construction of sexual experience developed an important critique of the biomedical and sexological approaches that had dominated the field over much of the twentieth century. In the second phase, increasingly detailed studies of sexual life were developed which highlighted the cross-cultural diversity of sexual cultures, sexual identities and sexual communities. In the most recent phase, there has been a growing recognition of the complex relationship between culture and power, and increasing attention to the political and economic dimensions of sexuality. In spite of the significant conceptual and methodological advances that have taken place over time, however, it is also possible to identify a number of important questions that have not yet been adequately addressed and that may have been precluded by some of the perspectives that have come to dominate the field. The paper ends by focusing on the silences and invisibilities that continue to characterize this field of research and the challenges that must still be confronted in seeking to expand our understanding of these issues.

Full Text Available Sensory evaluation of grapes (Vitis vinifera L. plays a key role in determining the harvest time in grapevine varieties. The harvest time of cv. Carménère is one of the latest of Chile. During the season 2007-2008, the evolution of the appearance of ‘Carménère’ seeds was evaluated as a harvest criterion, comparing it with the chemical and phenolic ripening. The samples were obtained from an organic vineyard located in Curicó Valley, Chile. Starting at 16 ºBrix, 100 seed berries samples were collected weekly from medium vigor vines in order to register photographically the ventral and dorsal sides of each seed. In addition to the seed tannins percentage, the extractable anthocyanins, total anthocyanins and total polyphenols index, as well as the titratable acidity, soluble solids and pH were registered. A color wheel of seed coat with a description of 12 digital colors was proposed for this cultivar. When the color number exceeded 10 (very dark brown, the soluble solids had already reached 24 ºBrix 1 month earlier. Two inverse correlations between seed coat color vs. seed phenols percentage and vs. total polyphenol index were found. The proper phenolic maturation (maximum anthocyanins and minimum seed tannins percentage occurred 177 d post flowering. The observation of seed coat color can be a reliable, simple and low-cost parameter to determine the correct ripeness of phenols in ‘Carménère’ grapevines.La evaluación sensorial de uvas (Vitis vinifera L. juega un rol clave en la determinación de la fecha de cosecha en los últimos estados de la maduración de la baya.

Sexuality usually decreases during pregnancy. To evaluate sexual behavior during pregnancy, comparing two groups. One had sexual education and the other had none. After randomizing two groups of pregnant women, they completed self-administered questionnaires regarding attitudes and sexual behavior before and during pregnancy. Sexual education was provided in one group and a second self-administered questionnaire was completed 12 weeks later. Responses were summarized using descriptive statistics. Comparison of change of sexual behavior between two groups was analyzed using chi-square and student t-tests. The change in frequency of coitus during pregnancy was compared between the sexual education group and the noneducation group. There was no statistically difference in changes of sexual behavior between the two groups. There was a reduction in frequency of coitus (90.6% vs. 94.9%, P>0.05) between the nonsexual education group and the sexual education group and no statistically significant change in mean reduction of sexual desire (8.9 vs. 4.4, P>0.05), sexual arousal (14.3 vs. 13.1, P>0.05), satisfaction from coitus (15.4 vs. 7.2, P>0.05), and orgasm from coitus (12.3 vs. 12.3, P>0.05). The change of sexual behavior during pregnancy in the sexual education group was not different from that in the nonsexual education group. © 2010 International Society for Sexual Medicine.

Sexual health is an integral part of the multifaceted human experience that is driven both by biological factors and psychological facets. Religion may provide a moral code of conduct or a sexual compass as to sexual norms and behaviors. The aim of this study was to summarize the integration of sexuality and religion. A review of published literature and religious texts was conducted. The integration of religion with country or state politics and laws is a complicated dilemma and will not be discussed in the scope of this article. The extent to which an individual incorporates their religious doctrine into their sexual life is a personal and individualized choice. The sexual medicine health professional will likely encounter a diverse patient population of distinct religious backgrounds, and a primer on religion and sexuality is a much needed adjunctive tool for the clinician. Because religion can influence sexuality and dictate, in part, the behavioral and medical treatments for sexual complaints, the clinician should be familiar with religious guidelines regarding sexuality, and treatment should be customized and individualized. Failure to do so can impact compliance with the therapeutic interventions. Religious awareness also solidifies the therapeutic alliance between clinician and patient as it demonstrates respect and acknowledgment for patient's beliefs and autonomy. © 2014 International Society for Sexual Medicine.

Internet Sexualities

Science.gov (United States)

Döring, Nicola

The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

Prevalence of dating violence among sexual minority youth: variation across gender, sexual minority identity and gender of sexual partners.

2015-01-01

Dating violence during adolescence negatively influences concurrent psychosocial functioning, and has been linked with an increased likelihood of later intimate partner violence. Identifying who is most vulnerable for this negative outcome can inform the development of intervention practices addressing this problem. The two goals of this study were to assess variations in the prevalence of dating violence across different measures of sexual minority status (e.g., sexual minority identity or same-sex sexual behavior), and to assess whether this association was mediated by bullying, the number of sexual partners, binge drinking or aggressive behaviors. These goals were assessed by employing the Massachusetts Youth Risk Behavior Survey (N = 12,984), a regionally representative sample of youth ages 14-18. In this sample, a total of 540 girls and 323 boys reported a non-heterosexual identity, and 429 girls and 230 boys reported having had one or more same-sex sexual partners. The results generally supported a higher prevalence of dating violence among sexual minority youth. This vulnerability varied considerably across gender, sexual minority identity and the gender of sexual partners, but generally persisted when accounting for the mediating variables. The findings support investigating dating violence as a mechanism in the disparities between sexual minority and heterosexual youth, and the importance of addressing sexual minority youth specifically in interventions targeting dating violence.

Full Text Available Sexual activity is a multifaceted activity, involving complex interactions between the nervous system, the endocrine system, the vascular system and a variety of structures that are instrumental in sexual excitement, intercourse and satisfaction. Sexual function has three components i.e., desire, arousal and orgasm. Many sexual dysfunctions can be categorized according to the phase of sexual response that is affected. In actual clinical practice however, sexual desire, arousal and orgasmic difficulties more often than not coexist, suggesting an integration of phases. Sexual dysfunction can result from a wide variety of psychological and physiological causes including derangements in the levels of sex hormones and neurotrensmitters. This review deals with the biology of different phases of sexual function as well as implications of hormones and neurotransmitters in sexual dysfunction

2016-09-01

Historically, women's sexual desire has been deemed socially problematic. The growing popularity of the concept of hypersexuality-which lists high sexual desire among its core components-poses a risk of re-pathologizing female sexual desire. Data from a 2014 online survey of 2,599 Croatian women aged 18-60 years was used to examine whether high sexual desire is detrimental to women's relationship and sexual well-being. Based on the highest scores on an indicator of sexual desire, 178 women were classified in the high sexual desire (HSD) group; women who scored higher than one standard deviation above the Hypersexual Disorder Screening Inventory mean were categorized in the hypersexuality (HYP) group (n = 239). Fifty-seven women met the classification criteria for both groups (HYP&HSD). Compared to other groups, the HSD was the most sexually active group. Compared to controls, the HYP and HYP&HSD groups-but not the HSD group-reported significantly more negative consequences associated with their sexuality. Compared to the HYP group, women with HSD reported better sexual function, higher sexual satisfaction, and lower odds of negative behavioral consequences. The findings suggest that, at least among women, hypersexuality should not be conflated with high sexual desire and frequent sexual activity.

To assess sexually related personal distress among premenopausal women with female sexual dysfunction (FSD) via a validated Arabic version of the Female Sexual Distress Scale (FSDS). A cross-sectional study was conducted among women attending Suez Canal University Hospital, Egypt, between May 2015 and July 2016. In a pilot study to evaluate test-retest reliability and internal consistency, 42 sexually active premenopausal women (aged ≥20 years) completed the Arabic FSDS at recruitment and 2 weeks later. Subsequently, premenopausal sexually active women (aged 20-45 years) were asked to complete the female sexual function index (FSFI) questionnaire; those with FSD (FSFI score ≤26.55) were invited to return to complete the validated version of the Arabic FSDS. The Arabic FSDS showed good test-retest reliability (Pearson correlation coefficient 0.93-0.98) and internal consistency (Cronbach α 0.83-0.92). Overall, 140 (58.1%) of 241 women who completed the FSFI had sexual dysfunction, of whom 51 (36.4%) had sexually related personal distress. Marriage duration was significantly increased among women with FSD (P<0.001). All FSFI sexual domains except lubrication were negatively correlated with FSDS. FSD and sexually related personal distress were highly interrelated and prevalent. An Arabic version of the FSDS was found to be valid and reliable for evaluation of sexually related personal distress. © 2017 International Federation of Gynecology and Obstetrics.

Full Text Available In the first half of the Nineteenth Century a large diversity of scientific activities were performed in Mexico City, establishing the foundation of a scientific culture. This paper will analyze its features, revealing the numerous activities of rational entertainment and learned performances that were complemented by the scientific contents of many literary magazines published during that time. As a result, the contents and values of Nineteenth Century science were appropriated by men and women of the middle and upper classes, who extended them into the larger public.Entre 1821 y 1860 la Ciudad de México fue escenario de una gran diversidad de actividades de talante científico en las que participó un público heterogéneo que no estuvo restringido a las élites intelectuales y que estableció las bases de una cultura proclive a todo tipo de ciencias. En este trabajo se examinarán sus rasgos a través de la exposición de las diversas actividades científicas de entretenimiento racional y espectáculos cultos que se ofrecieron en el ámbito urbano y que tuvieron como complemento los contenidos de las ciencias difundidos en las numerosas revistas literarias de la primera mitad de la centuria. De esta manera, tanto hombres como mujeres con ciertos recursos económicos, tiempo libre, instrucción más allá de las primeras letras y hábitos de lectura, tuvieron la oportunidad de acceder a los contenidos y los valores de la ciencia de su tiempo, que ellos mismos extenderían a un público más amplio.

Norton, Melanie K; Smith, Megan V; Magriples, Urania; Kershaw, Trace S

This study examined the relationship between traditional masculine role norms (status, toughness, anti-femininity) and psychosocial mechanisms of sexual risk (sexual communication, sexual self-efficacy) among young, low-income, and minority parenting couples. Between 2007 and 2011, 296 pregnant adolescent females and their male partners were recruited from urban obstetrics clinics in Connecticut. Data regarding participants' beliefs in masculine role norms, frequency of general sex communication and sexual risk communication, and sexual self-efficacy were collected via computer-assisted self-interviews. Generalized estimating equation (GEE) models were used to test for actor effects (whether a person's masculine role norms at baseline influence the person's own psychosocial variables at 6-month follow-up) and partner effects (whether a partner's masculine role norms at baseline influence an actor's psychosocial variables at 6-month follow-up). Results revealed that higher actor status norms were significantly associated with more sexual self-efficacy, higher actor toughness norms were associated with less sexual self-efficacy, and higher actor anti-femininity norms were significantly associated with less general sex communication, sexual risk communication, and sexual self-efficacy. No partner effects were found. These results indicate a need for redefining masculine role norms through family centered approaches in pregnant or parenting adolescent couples to increase sexual communication and sexual self-efficacy.

Sexual problems in men and women are common; and physicians endorse many barriers to addressing these issues, including lack of knowledge about the diagnosis and management of sexual problems and inadequate training in sexual health communication and counseling. To update the recommendations published in 2004, from the International Consultation on Sexual Medicine (ICSM) relevant to the educational aspects of sexual health in undergraduate, graduate, and postgraducate medical education. A third international consultation in collaboration with the major sexual health organizations assembled over 186 multidisciplinary experts from 33 countries into 25 committees. Three experts from three countries contributed to this committee's review of Education in Sexual Medicine. Expert opinion was based on a comprehensive review of the medical literature, committee discussion, public presentation, and debate. A comprehensive review about the current state of undergraduate, graduate, and postgraduate sexual health education worldwide is provided. Recommendations about ideal sexual health curricula across training levels are provided. Best methods for achieving optimal training approaches to sexual health communication and interviewing, clinical skills and management, and counseling are described. Current sexual health education for undergraduate and practicing physicians is inadequate to meet the advancing science and technology and increasing patient demand for high-quality sexual health care. There is a need for enhanced training in medical institutions responsible for physician sexual health training worldwide. Future training programs at all levels of medical education should incorporate standardized measures of sexual health clinical skills acquisition and assessments of the impact on patient outcomes into the design of educational initiatives. © 2010 International Society for Sexual Medicine.

A growing prevalence of unexpected pregnancies and younger age of sexual debut is observed among Chinese young people, while they lack formal sexuality education from schools and parents. It is necessary to measure their knowledge level of sexual and reproductive health, and how such knowledge associates with their sexual behaviors and reproductive health outcomes, which would shed light on the effectiveness of sexuality education in China. An Internet-based questionnaire survey was conducted from January to August, 2015. 130 colleges were selected from eastern, central, and western parts China with a good balance of geographic distributions. The survey link was subsequently delivered to the focal points in each college for voluntary participation, targeting on undergraduates aged 18 ~ 25. Information on demographics, experience of school-based sexuality education (defined as any course introducing information on sexual and reproductive health) and SRH knowledge quiz was collected. Multivariate linear regression and logistic regression were applied to explore the relationship between students' SRH knowledge, sexual behaviors and reproductive health outcomes, such as sexual intercourse (penetrative sex by vaginal or anal), unprotected sex, pregnancy and abortion, etc. A total sample of 17,966 Chinese college students (mean age = 20.2, 60.4% female) eventually entered the analysis. Only 55.6% of the respondents self-reported having received sexuality education before, and they scored significantly higher (2.33/4.00) in the SRH knowledge quiz than those who had not (1.75/4.00). Among the sexually experienced students (n = 3639, 20.2%), both males and females with higher SRH knowledge were less likely to report having experience of (partner's) pregnancy or abortion (OR sexually experienced males, those with higher SRH knowledge had a slightly later age of sexual debut (coefficient = 0.28, p sexual intercourses (OR = 0.82, 95%C.I.: 0.69 ~ 0.96).

Sexual self-schemas are cognitive generalizations regarding sexual aspects of the self that represent a core component of one's sexuality. We contend that individual differences in the sexual self-view represent an important cognitive diathesis for predicting sexual difficulty or dysfunction. We illustrate the role of sexual self-schemas on sexual behavior and responsiveness in healthy female and male samples. Next, we describe how diathesis-stress models of psychopathology have been applied to the sexual arena, and discuss the critical features of clinically useful diathesis variables. Drawing from these criteria, we examine the diathetic properties of sexual self-schemas. Finally, we discuss an empirical test of the proposed diathesis-stress interaction, reviewing the role of women's sexual self-views on sexual morbidity following diagnosis and treatment for gynecologic cancer.

The purpose of this study was to evaluate whether a comprehensive sexual education program for college students in Southwest China (a) improved sexual health knowledge in reproduction, contraception, condom use, sexually transmitted diseases, and HIV; (b) increased accepting attitudes toward lesbian, gay, bisexual, and transsexual individuals; and (c) altered participants' attitudes toward premarital sex and monogamy. The program used diverse teaching methods, providing 6 sessions over a period of 9 weeks about sexual health knowledge and sexual attitudes to college students (age 18-26 years) in Southwest China. Sexual health knowledge and sexual attitudes of 80 comprehensive sexual education class students (education group) and 92 general mental health education class students (control group) were measured at baseline, the end of course (posttest), and 3 weeks after the end of course (follow-up). There were significant effects of the program on (a) sexual health knowledge, including reproductive health, contraception, condom use, and HIV/AIDS and (b) positive attitudes toward sexual minorities, although these changes may require further reinforcement. In contrast, the program did not alter students' attitudes about premarital sex or monogamy. The results are discussed in terms of recommendations of sex education in China and future directions for research. © 2013 APJPH.

Although a large body of previous research has examined sexual behavior and its relation to risk in men of diverse sexual identities, most studies have relied on convenience sampling. As such, the vast majority of research on the sexual behaviors of gay and bisexual men, in particular, might not be generalizable to the general population of these men in the United States. This is of particular concern because many studies are based on samples of men recruited from relatively "high-risk" venues and environments. To provide nationally representative baseline rates for sexual behavior in heterosexual, gay, and bisexual men in the United States and compare findings on sexual behaviors, relationships, and other variables across subgroups. Data were obtained from the 2012 National Survey of Sexual Health and Behavior, which involved the administration of an online questionnaire to a nationally representative probability sample of women and men at least 18 years old in the United States, with oversampling of self-identified gay and bisexual men and women. Results from the male participants are included in this article. Measurements include demographic characteristics, particularly sexual identity, and their relations to diverse sexual behaviors, including masturbation, mutual masturbation, oral sex, vaginal sex, and anal sex. Behaviors with male and female partners were examined. Men of all self-identified sexual identities reported engaging in a range of sexual behaviors (solo and partnered). As in previous studies, sexual identity was not always congruent for gender of lifetime and recent sexual partners. Patterns of sexual behaviors and relationships vary among heterosexual, gay, and bisexual men. Several demographic characteristics, including age, were related to men's sexual behaviors. The results from this probability study highlight the diversity in men's sexual behaviors across sexual identities, and these data allow generalizability to the broader population of

We examined associations between adolescent girls' sexual identity and the gender of their sexual partners, on one hand, and their reports of sexual health behaviors and reproductive health outcomes, on the other. We analyzed weighted data from pooled Youth Risk Behavior Surveys (2005 and 2007) representative of 13 US jurisdictions, focusing on sexually experienced girls in 8th through 12th grade (weighted n=6879.56). We used logistic regression with hierarchical linear modeling to examine the strength of associations between reports about sexual orientation and sexual and reproductive health. Sexual minority girls consistently reported riskier behaviors than did other girls. Lesbian girls' reports of risky sexual behaviors (e.g., sex under the influence of drugs or alcohol) and negative reproductive health outcomes (e.g., pregnancy) were similar to those of bisexual girls. Partner gender and sexual identity were similarly strong predictors of all of the sexual behaviors and reproductive health outcomes we examined. Many sexual minority girls, whether categorized according to sexual identity or partner gender, are vulnerable to sexual and reproductive health risks. Attention to these risks is needed to help sexual minority girls receive necessary services.

Several studies have demonstrated that culture plays a fundamental role in individuals' beliefs, attitudes, and values toward sexuality, and influences their ability to enjoy sex. It follows that culture may influence sexual satisfaction or dissatisfaction. To examine and compare cognitive-emotional variables related to women's sexual dissatisfaction in Iran and New Zealand. In total, 196 Iranian women and 207 New Zealand women participated in the study, answering questionnaires evaluating dysfunctional sexual beliefs, automatic thoughts, emotional and sexual response during sexual activity, as well as sexual satisfaction. Sexual beliefs were measured by the Sexual Dysfunctional Beliefs Questionnaire, thoughts and emotional responses were measured by the Sexual Modes Questionnaire, and sexual satisfaction was measured by the Sexual Satisfaction Index. Findings indicated that in both Iranian and New Zealand women, failure and disengagement thoughts, lack of erotic thoughts, and emotions of fear during sexual activity were significant predictors of sexual dissatisfaction. Besides these common predictors, results also indicated that sexual conservatism and women's sexual passivity beliefs, sexual abuse thoughts, and fear during sexual activity were significant predictors of sexual dissatisfaction in Iranian women. Beliefs of sexual desire and pleasure as a sin; age-related beliefs; and emotions such as sadness, disillusion, and hurt were significant predictors of sexual dissatisfaction in New Zealand women. The present findings could facilitate a better understanding of cultural differences in the roles played by dysfunctional sexual beliefs, negative automatic thoughts, and negative emotions during sexual activity, and the value of these beliefs, thoughts, and emotions in predicting sexual dissatisfaction. The strength of this study is in providing an examination of the role of culturally bound beliefs in predicting sexual dissatisfaction in women from different

Appraisal and control of sexual and non-sexual intrusive thoughts in university students.

Clark, D A; Purdon, C; Byers, E S

2000-05-01

This study examined differences in the appraisal and thought control strategies associated with the perceived control of unwanted sexual and non-sexual intrusive thoughts. Eleven appraisal dimensions, subjective physiological arousal and 10 thought control strategies were measured in 171 university students who were administered the Revised Obsessive Intrusions Inventory-Sex Version, a self-report measure of unwanted intrusive thoughts. Thought-action fusion (TAF) likelihood was a significant unique predictor of the perceived controllability of respondents' most upsetting sexual and non-sexual intrusive thought. Moreover greater subjective physiological arousal was a significant predictor of reduced control over sexual intrusions, whereas worry that one might act on an intrusive thought and greater effort to control the intrusion were significant unique predictors of the control of non-sexual intrusive thoughts. Various thought control strategies were more often used in response to non-sexual than sexual cognitions. The results are discussed in terms of the differential role of various appraisal processes in the control of unwanted sexual and non-sexual thoughts.

Traditional health education may not provide adequate sexual information to female adolescents. Sexual health education for female adolescents broadens opportunities for nurses to help female adolescents adopt appropriate sexual attitudes and make appropriate decisions. The purpose of this study was to understand the effect of sexual empowerment on sexual decision making in female adolescents. Twenty-nine female students with steady boyfriends were invited to participate in a sexual empowerment course. Course activities specifically related to sexual empowerment were audio-tape-recorded. Dialogue content was analyzed, and content provided by each study participant was reconfirmed in face-to-face interviews to understand the entire empowerment process in terms of how such may affect responses and to assess the possibility of correctly reinterpreting findings during the member check process. This study also took into consideration degrees of reliability and rigorousness. The four themes found to underlie participant perceptions of their sexual empowerment to make sex-related decisions were as follows: (a) proactively seeking sexual knowledge, (b) reexamining relationships with boyfriends, (c) the right to say "no" and to engage in self-protection, and (d) the need to change sexual attitudes and behaviors. Using the peer group intervention in sexual empowerment may positively impact sexual health decision making in adolescent girls. Nursing professionals may consider peer group intervention as a sexual empowering method in healthcare.

Sexual Jealousy

Directory of Open Access Journals (Sweden)

David M. Buss

2013-09-01

Full Text Available Sexual jealousy is a basic emotion. Although it lacks a distinctive facial expression and is unlikely to solve problems of survival, it evolved because it solves adaptive problems of mating. Some adaptive functions are similar in men and women at one level of abstraction, such as warding off potential mate poachers and deterring relationship defection. Other functions are sex-differentiated, such as increasing paternity probability for men and monopolizing a mate's economic commitments for women. Dozens of studies have documented sex-differentiated design features of jealousy: The relative upset about sexual and emotional aspects of infidelity; processing speed and memorial recall of sexual and emotional infidelity cues; physiological distress to sexual and emotional infidelity cues; qualities of same-sex rivals that evoke jealousy, such as superior job prospects versus greater physical attractiveness; triggers of mate retention tactics; jealous interrogations following the discovery of infidelity; and whether an infidelity produces forgiveness or breakup. Although showing all the hallmarks of evolved functionality, sexual jealousy also leads to tremendous destruction, from humiliation to homicide. By these scientific theoretical and empirical criteria, sexual jealousy is properly considered not only "basic" but also "one of the most important emotions".

Sexual identity, sexual attraction and sexual experience: the Second Australian Study of Health and Relationships.

Background Behavioural and other aspects of sexuality are not always consistent. This study describes the prevalence and overlap of same-sex and other-sex attraction and experience and of different sexual identities in Australia. Computer-assisted telephone interviews were completed by a representative sample of 20094 men and women aged 16-69 years recruited by landline and mobile phone random-digit dialling with a response rate (participation rate among eligible people) of 66.2%. Respondents were asked about their sexual identity ('Do you think of yourself as' heterosexual/straight, homosexual/gay, bisexual, etc.) and the sex of people with whom they had ever had sexual contact and to whom they had felt sexually attracted. Men and women had different patterns of sexual identity. Although the majority of people identified as heterosexual (97% men, 96% women), women were more likely than men to identify as bisexual. Women were less likely than men to report exclusively other-sex or same-sex attraction and experience; 9% of men and 19% of women had some history of same-sex attraction and/or experience. Sexual attraction and experience did not necessarily correspond. Homosexual/gay identity was more common among men with tertiary education and living in cities and less common among men with blue-collar jobs. Many gay men (53%) and lesbians (76%) had some experience with an other-sex partner. More women identified as lesbian or bisexual than in 2001-02. Similarly, more women reported same-sex experience and same-sex attraction. In Australia, men are more likely than women to report exclusive same-sex attraction and experience, although women are more likely than men to report any non-heterosexual identity, experience and attraction. Whether this is a feature of the plasticity of female sexuality or due to lesser stigma than for men is unknown.

Sexual prejudice.

Herek, Gregory M; McLemore, Kevin A

2013-01-01

Despite shifts toward greater acceptance in U.S. public opinion and policy, lesbian, gay, and bisexual people remain widely stigmatized. This article reviews empirical research on sexual prejudice, that is, heterosexuals' internalization of cultural stigma, manifested in the form of negative attitudes toward sexual minorities and same-sex desires and behaviors. After briefly reviewing measurement issues, we discuss linkages between sexual prejudice and religion, gender, sexuality, and related variables, and consider how the cultural institutions encompassing these domains create a social context within which individual expressions of prejudice can meet important psychological needs. These include needs for securing social acceptance, affirming values that are central to one's self-concept, and avoiding anxiety and other negative emotions associated with threats to self-esteem. We conclude by discussing factors that may motivate heterosexuals to reduce their own sexual prejudice, including intergroup contact, as well as avenues for future empirical inquiry.

Sexuality in later life and its relationship to dementia is a neglected topic: greater understanding of the area has the potential to contribute to the quality of life of people with dementia, their family members, and formal carers. We review current knowledge about sexuality, aging, and dementia. We undertook a review of the recent literature to examine of the following areas: what is known about sexuality and aging, and about attitudes to sexuality and aging; what is known about the relevance of sexuality and aging to people living with dementia and their care; and the management of sexual behaviors causing concern to others. Sexual activity decreases in frequency with increasing age but many older people remain sexually active; there is no age limit to sexual responsiveness; and sexuality is becoming more important to successive cohorts of older people, including people living with dementia and gay, lesbian, bisexual, and transgendered elderly people. Attitudes and beliefs toward sexuality and aging are strongly influenced by stereotypes and myths, not only among the general public but also among those working in health and social care. Professional bodies should include sexuality, aging, and dementia in their training curricula. More work is needed on the impact of environmental issues, particularly in group living situations, on older adults' sexuality, and on consent issues. Ethical decision-making frameworks can be useful in practice. Organizations should investigate how to support staff in avoiding a problem-orientated approach and focus on providing holistic person-centered care.

2017-03-01

This article presents a longitudinal analysis of the links between sexual assault victimization, depression, and sexual self-esteem by examining their cross-lagged paths among both men and women. Male and female college students (N = 2,425) in Germany participated in the study that comprised 3 data waves in their first, second, and third year of university, separated by 12-month intervals. Sexual assault victimization was assessed at Time 1 (T1) since the age of 14 and at Time 2 (T2) and Time 3 (T3) for the last 12 months. Depression and sexual self-esteem were measured at each wave. Random-intercept cross-lagged panel analyses, controlling for individual differences in depression and sexual self-esteem, showed that sexual assault at T1 predicted depression and lower sexual self-esteem at T2, and depression and lower self-esteem at T2 predicted sexual assault victimization at T3. In addition, significant paths were found from T1 depression to T2 sexual assault victimization and from T2 sexual assault victimization to depression at T3. Sexual victimization at T1 was indirectly linked to sexual victimization at T3 via depression at T2. Both depression and sexual self-esteem at T1 were indirectly linked to sexual victimization at T3. The paths did not differ significantly between men and women. Sexual assault victimization was shown to be a risk factor for both depression as a general mental health indicator and lowered sexual self-esteem as a specific outcome in the domain of sexuality. Moreover, depression and sexual self-esteem increased the vulnerability for sexual assault victimization, which has implications for prevention and intervention efforts.

A narrow view: The conceptualization of sexual problems in human sexuality textbooks.

Stelzl, Monika; Stairs, Brittany; Anstey, Hannah

2018-02-01

This study examined the ways in which the meaning of 'sexual problems' is constructed and defined in undergraduate human sexuality textbooks. Drawing on feminist and critical discourse frameworks, the dominant as well as the absent/marginalized discourses were identified using critical discourse analysis. Sexual difficulties were largely framed by the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. Thus, medical discourse was privileged. Alternative conceptualizations and frameworks, such as the New View of Women's Sexual Problems, were included marginally and peripherally. We argue that current constructions of sexuality knowledge reinforce, rather than challenge, existing hegemonic discourses of sexuality.

Sexual gender norms promoting sexual prowess for men, but sexual modesty for women have been shown to negatively affect sexual and mental health in both men and women. Knowledge about the relationship between gender norms and sexual cognitions and emotions might further the understanding of continued gender-norm conformity. In the present study, we investigated whether and how gendered sexual attitudes are related to (positive and negative) sex-related emotions, via sexual cognitions (autonomy, body esteem, and approach/avoidance motives for sex). A survey was submitted to 293 heterosexually identified, sexually active, Dutch (central and southern regions) 18-25 year-olds. Results from a moderated mediation model (using structural equation modeling) revealed that women, but not men, who more strongly endorsed traditional gender-related sexual attitudes experienced significantly less positive and more negative emotions, as a result of decreased sexual autonomy and sexual body esteem as well as increased avoidance motives for sex. We conclude that, as a result of negative cognitions associated with the endorsement of traditional gender norms, women in particular are at risk of experiencing negative emotional outcomes in the sexual context. We argue that sexual cognitions and emotions deserve explicit attention in sex-positive and gender-transformative sexuality education, which has been proven to be a vital resource for achieving increased gender-equity in sexual and romantic relationships.

Full Text Available CONTEXTO: A demência pode resultar em comprometimento da intimidade e sexualidade de casais idosos. OBJETIVOS: Avaliar alterações na atividade sexual, bem como os fatores de satisfação e/ou insatisfação sexual de casais nos quais um dos parceiros possua demência. MÉTODO: Busca nas bases de dados ISI, PubMed/Medline e SciELO de artigos sobre sexualidade na demência, entre janeiro de 1990 e março de 2012, utilizando as palavras-chave: "demência", "satisfação sexual", "intimidade" e "sexualidade". RESULTADOS: Foram encontrados 12 artigos. A sobrecarga de cuidados e a alteração de papéis na relação conjugal foram consideradas as principais causas para o declínio da atividade sexual. A disfunção erétil em pacientes e cônjuges, a capacidade decisória para o consentimento da relação sexual por parte do paciente demenciado e os problemas referentes à idade e à saúde (física e emocional do cônjuge e/ou paciente foram os fatores associados à insatisfação sexual. CONCLUSÃO: A intimidade e a atividade sexual dos casais em que um dos parceiros é portador de demência são influenciadas negativamente pela relação de cuidados decorrente da doença e pela sobrecarga dos cônjuges. Por outro lado, a atividade sexual pode ser positivamente substituída por demonstrações de carinho e empatia entre os cônjuges.BACKGROUND: Dementia may result on impairment in intimacy and sexuality of elderly couples.

Full Text Available Haciendo uso de bases de datos históricas del Proceso de Admisión a la Educación Superior en Chile, mediante un análisis estadístico inferencial y comparativo, este artículo tiene como objetivo analizar a estudiantes “Primera Generación” y sus elecciones profesionales, contrastándolo con el estudiante “Continuista”. Los principales hallazgos informan sobre la existencia de atributos y comportamientos diferenciales del estudiante “Primera Generación” respecto del alumno “Continuista”, dando cuenta de la persistencia de procesos de exclusión y segregación que se manifiestan en una elección profesional fuertemente condicionada por el habitus que reproduce desigualdades y limita las aspiraciones a un conjunto restringido de opciones. Este escenario pone en cuestión el real ejercicio de la opción vocacional así como la mayor democratización e inclusión de un sistema de educación superior masificado y diversificado.

Relationship between short-term sexual strategies and sexual jealousy.

Science.gov (United States)

Mathes, Eugene W

2005-02-01

In a classic study, Buss, Larson, Westen, and Semmelroth reported that men were more distressed by the thought of a partner's sexual infidelity (sexual jealousy) and women were more distressed by the thought of a partner's emotional infidelity (emotional jealousy). Initially, Buss and his associates explained these results by suggesting that men are concerned about uncertainty of paternity, that is, the possibility of raising another man's child while believing the child is their own. However, later they explained the results in terms of men's preference for short-term sexual strategies. The purpose of this research was to test the explanation of short-term sexual strategies. Men and women subjects were instructed to imagine themselves in a relationship which was either short-term (primarily sexual) or long-term (involving commitment) and then respond to Buss's jealousy items. It was hypothesized that, when both men and women imagined a short-term relationship, they would be more threatened by a partner's sexual infidelity, and, when they imagined a long-term relationship, they would be more threatened by a partner's emotional infidelity. Support was found for this hypothesis.

Purpose Childhood and adolescent sexual abuse has been shown to lead to increased odds of sexual behaviors that lead to sexually transmitted infections and early pregnancy involvement. Research, meta-analyses, and interventions, however, have focused primarily on girls and young women who have experienced abuse, yet some adolescent boys are also sexually abused. We performed a meta-analysis of the existing studies to assess the magnitudes of the link between a history of sexual abuse and each of three risky sexual behaviors among adolescent boys in North America. Methods The three outcomes were a) unprotected sexual intercourse, b) multiple sexual partners, and c) pregnancy involvement. Weighted mean effect sizes were computed from 10 independent samples, from nine studies published between 1990 and 2011. Results Sexually abused boys were significantly more likely than non-abused boys to report all three risky sexual behaviors. Weighted mean odds ratios were 1.91 for unprotected intercourse, 2.91 for multiple sexual partners, and 4.81 for pregnancy involvement. Conclusions Our results indicate that childhood and adolescent sexual abuse can substantially Influence sexual behavior in adolescence among male survivors. To improve sexual health for all adolescents, even young men, we should strengthen sexual abuse prevention initiatives, raise awareness about male sexual abuse survivors’ existence and sexual health issues, improve sexual health promotion for abused young men, and screen all people, regardless of gender, for a history of sexual abuse.

Full Text Available This article examines three works by Gregorio Marañón, published for the first time in 1926 under the epigraph Tres ensayos sobre la vida sexual [Three essays on sexual life]. These essays had a huge impact and they were republished several times. The aim of this paper is to help situate Marañon’s medical and scientific views, as expressed in these essays, in the political, scientific and socio-cultural context of 1920s Spain. Marañón’s theory of sexual differentiation and his defence of women’s maternal mission is discussed at a time when many feminists accepted a sexualised view of the world in which women’s identity was articulated around motherhood. The analysis of these essays is framed in the contemporary historiography on sexuality and women’s history.En este artículo se examinan tres trabajos de Gregorio Marañón, publicados por primera vez en 1926 y agrupados bajo el epígrafe de Tres ensayos sobre la vida sexual. Estos ensayos tuvieron una gran resonancia y fueron objeto de numerosas ediciones. El objetivo de este trabajo es contribuir a situar las posiciones científicas y médicas, expresadas por Marañón en estos ensayos, en el contexto socio-cultural, científico y político de la España de la década de 1920. Se discute la teoría de la diferenciación sexual de Marañón y su defensa de la misión maternal de las mujeres en una época en la que muchas feministas asumieron una visión sexualizada del mundo y en la que la identidad femenina se articulaba en torno a la maternidad. El análisis de estos ensayos es enmarcado en la historiografía contemporánea sobre la historia de la sexualidad y la historia de las mujeres.

Although having a sexual victimization history is associated with engaging in sexual risk behavior, the mechanisms whereby sexual victimization increases risk behavior are unclear. This study examined use of sex as an affect regulation strategy as a mediator of the relationship between depressive symptoms and sexual risk behavior among 1,616 sexually active college women as well as examined having a history of child sexual abuse (CSA), adolescent/adult sexual assault (ASA), or both (CSA/ASA) as moderators. Results supported the mediated model as well as moderated mediation, where depressive symptoms were more strongly associated with use of sex as an affect regulation strategy among ASA victims, and sex as an affect regulation strategy was more strongly related to sexual risk behavior for CSA/ASA victims.

Beyond lesbian bed death: enhancing our understanding of the sexuality of sexual-minority women in relationships.

Cohen, Jacqueline N; Byers, E Sandra

The goal of this study was to characterize the sexuality of sexual-minority (i.e., lesbian, bisexual, queer, unlabeled, questioning) women. Participants were 586 women (87% White) in a same-sex relationship of 1 to 36 years in duration. They completed measures assessing their sexual behavior (frequency of nongenital and genital sexual activities), motivation (sexual desire), and cognitive-affective responses (sexual satisfaction, sexual esteem, sexual anxiety, negative automatic thoughts). On average, the women reported experiencing their sexuality positively across all domains. Regardless of relationship duration, most of the women reported engaging in both genital and nongenital sexual behaviors with their partner once a week or more; few reported that they had not engaged in sexual activity in the previous month. A multiple regression analysis indicated that frequency of genital sexual activity, sexual desire, sexual anxiety, and automatic thoughts contributed uniquely to the prediction of sexual satisfaction over and above the other sexuality variables. The findings are discussed in terms of the idea that lesbians have sex less frequently than other couple types and that sexual frequency declines rapidly in lesbian relationships (i.e., "lesbian bed death") and descriptions of sexual-minority women's sexuality that suggest that genital sexual activity is not important to sexual satisfaction.

While there is increasing interest in studying aspects of communication processes in sex research, the association between dyadic sexual communication and relationship and sexuality outcomes has not yet been examined in pre-menopausal women with dyspareunia. To examine the associations between dyadic sexual communication and pain, sexual distress, sexual function and dyadic adjustment in women with self-reported dyspareunia and their male partners. Pre-menopausal women (n=38; M age=24.92, SD=6.12) with self-reported dyspareunia from a community sample and their partners (n=38; M age=26.71, SD=6.59) completed an online survey. The Actor-Partner Interdependence Model was used in order to investigate both actor and partner effects. Both members of the couple completed: (i) the Dyadic Sexual Communication Scale and (ii) the Dyadic Adjustment Scale; women also completed (iii) the Female Sexual Function Index, (iv) the Female Sexual Distress Scale, and (v) a Visual Analogue Scale on pain during intercourse; and men also completed (vi) the International Index of Erectile Functioning. Controlling for relationship duration, women's better dyadic sexual communication was significantly associated with their higher levels of sexual function (P=0.028), lower levels of sexual distress (P=0.003) and higher levels of dyadic adjustment (P=0.005), but not with their pain or men's sexual function or dyadic adjustment. Controlling for relationship duration, men's better dyadic sexual communication was associated with their higher levels of dyadic adjustment (P=0.027) but not with their sexual function, nor with women's sexual function or dyadic adjustment. These findings contribute to the theoretical knowledge on interaction processes in couples with dyspareunia and suggest that it may be important to enhance open and direct communication about sexual matters in couples with dyspareunia. © 2014 International Society for Sexual Medicine.

Why is impaired sexual function distressing to women? The primacy of pleasure in female sexual dysfunction.

Stephenson, Kyle R; Meston, Cindy M

Recent research has highlighted a complex association between female sexual function and subjective distress regarding sexual activity. These findings are difficult to explain given limited knowledge as to the mechanisms through which impaired sexual function causes distress. The current study assessed whether a number of specific consequences of impaired sexual function, including decreased physical pleasure, disruption of sexual activity, and negative partner responses, mediated the association between sexual function and distress. Eighty-seven women in sexually active relationships reporting impairments in sexual function completed validated self-report measures and daily online assessments of sexual experiences. Participants completed the Sexual Satisfaction Scale for Women, the Female Sexual Function Index, and the Measure of Sexual Consequences. Results suggested that decreased physical pleasure and disruption of sexual activity, but not partner responses, statistically mediated the association between sexual function and distress. Sexual consequences represent potential maintaining factors of sexual dysfunction that are highly distressing to women. Results are discussed in the context of theoretical models of sexual dysfunction and related treatments. © 2014 International Society for Sexual Medicine.

The aim of this study was to evaluate the potential relationship between self-reported sexual dysfunction, sexual behavior, and severity of addiction of drug users. A cross-sectional design study was conducted at an inpatient addiction treatment unit in Sao Paulo, Brazil, with a sample of 508 male drug users. Sociodemographic data, sexual behavior, and severity of dependence were evaluated.The prevalence of sexual dysfunction was 37.2% and premature ejaculation was 63.8%. Men with sexual dysfunction presented from moderate to severe level of alcohol, tobacco, and other drugs of dependence. The findings from this study are particularly relevant identifying those sociodemographic factors, severity of drug use, and sexual behavior are related to men who experience sexual dysfunction. Health promotion and motivational interventions on sexual health targeted to male drug users can contribute in reducing these at-risk behaviors. More interdisciplinary research is desirable in future in considering men's sexual health. © The Author(s) 2015.

The sexual attitudes and activities of 77 sexually abused and 89 comparison women (mean age = 20.41, SD = 3.38) were assessed 10 years after disclosure in a longitudinal, prospective study of the long-term effects of childhood sexual abuse. Abused participants were more preoccupied with sex, younger at first voluntary intercourse, more likely to have been teen mothers, and endorsed lower birth controlefficacy than comparison participants. When psychological functioning earlier in development was examined, sexual preoccupation was predicted by anxiety, sexual aversion was predicted by childhood sexual behavior problems, and sexual ambivalence (simultaneous sexual preoccupation and sexual aversion) was predicted by pathological dissociation. Findings also indicate that biological father abuse may be associated with greater sexual aversion and sexual ambivalence.

Domestic violence is a universal problem, and sexual violence in marriage, in particular, is a hidden form of it. This descriptive, cross-sectional study was conducted to determine to the prevalence of domestic sexual violence by husbands, the prevalence of sexual problems, and the relation of these among married women attending a gynecology outpatient clinic. This study was performed in a university hospital in Turkey and data were collected February-April 2009. The study sample consisted of 200 married women, 53% of whom reported having been exposed to at least one type of domestic sexual violence behaviors by their husbands. Among those behaviors, the rate of marital rape was 33%. The frequency of experiencing any sexual problem was 82%. Women expressed that they mostly had orgasmic problems, and their husbands had premature ejaculation problems. The majority of women who reported sexual violence reported experiencing sexual problems; the frequency of sexual problems was higher in the participants who did (94.3%) than in those who did not report (68.1%) sexual violence (p violence in marriage. The results also revealed that the prevalence of sexual violence and sexual problems among those married women who attended gynecology clinics was considerable, even though they did not report this to the health care provider as a problem.

Animal Models in Sexual Medicine: The Need and Importance of Studying Sexual Motivation.

Science.gov (United States)

Ventura-Aquino, Elisa; Paredes, Raúl G

2017-01-01

Many different animal models of sexual medicine have been developed, demonstrating the complexity of studying the many interactions that influence sexual responses. A great deal of effort has been invested in measuring sexual motivation using different behavioral models mainly because human behavior is more complex than any model can reproduce. To compare different animal models of male and female behaviors that measure sexual motivation as a key element in sexual medicine and focus on models that use a combination of molecular techniques and behavioral measurements. We review the literature to describe models that evaluate different aspects of sexual motivation. No single test is sufficient to evaluate sexual motivation. The best approach is to evaluate animals in different behavioral tests to measure the motivational state of the subject. Different motivated behaviors such as aggression, singing in the case of birds, and sexual behavior, which are crucial for reproduction, are associated with changes in mRNA levels of different receptors in brain areas that are important in the control of reproduction. Research in animal models is crucial to understand the complexity of sexual behavior and all the mechanisms that influence such an important aspect of human well-being to decrease the physiologic and psychological impact of sexual dysfunctions. In other cases, research in different models is necessary to understand and recognize, not cure, the variability of sexuality, such as asexuality, which is another form of sexual orientation.
