Sex

Men's voices contain acoustic cues to body size and hormonal status, which have been found to affect women's ratings of speaker size, masculinity and attractiveness. However, the extent to which these voice parameters mediate the relationship between speakers' fitness-related features and listener's judgments of their masculinity has not yet been investigated. We audio-recorded 37 adult heterosexual males performing a range of speech tasks and asked 20 adult heterosexual female listeners to rate speakers' masculinity on the basis of their voices only...

Facial attractiveness provides a very powerful motivation for sexual and parental behavior. We therefore review the importance of faces to the study of neurobiological control of human reproductive motivations. For heterosexual individuals there is a common brain circuit involving the nucleus accumbens, the medial prefrontal, dorsal anterior cingulate and the orbitofrontal cortices that is activated more by attractive than unattractive faces, particularly for faces of the opposite sex. Behavioral studies indicate parallel effects of attractiveness on incentive salience or willingness to work to see faces...

We investigated the impact of sexual stimuli and the influence of sexual motivation on the performance in a dot-probe task and a line-orientation task in a large sample of males and females. All pictures (neutral, erotic) were rated on the dimensions of valence, arousal, disgust, and sexual arousal. Additionally, questionnaires measuring sexual interest/desire/motivation were employed. The ratings of the sexual stimuli point to a successful picture selection because sexual arousal did not differ between the sexes...

Research has shown that processing dynamics on the perceiver's end determine aesthetic pleasure. Specifically, typical objects, which are processed more fluently, are perceived as more attractive. We extend this notion of perceptual fluency to judgments of vocal aesthetics. Vocal attractiveness has traditionally been examined with respect to sexual dimorphism and the apparent size of a talker, as reconstructed from the acoustic signal, despite evidence that gender-specific speech patterns are learned social behaviors...

A large literature proposes that preferences for exaggerated sex typicality in human faces (masculinity/femininity) reflect a long evolutionary history of sexual and social selection. This proposal implies that dimorphism was important to judgments of attractiveness and personality in ancestral environments. It is difficult to evaluate, however, because most available data come from large-scale, industrialized, urban populations. Here, we report the results for 12 populations with very diverse levels of economic development...

The author demonstrates, through clinical case illustration, how sexual perversion is linked to traumatic early separation-individuation processes. The illusion of fusion with a seductive and gratifying mother-introject led a young man into the risky business of unprotected gay sex with strangers. The pleasure-seeking child and enabling mother narrative was played out in the transference/counter-transference relationship threatening to pervert the analysis. Authoritative limit setting re-introduced a potent, previously castrated, father figure into the patient's inner world and gave the patient impetus to separate from the undifferentiated mix-up between mother and child, resulting in containment of dangerous sexual behaviors...

An appreciation of the social, cultural and economic dimensions of gender and sexuality is important in increasing reproductive health service utilisation. This analysis of recent Mexican male immigrants in Southern California focuses on changing views of gender roles, masculinity and relationship dynamics in the context of migration in order to explain low levels of reproductive healthcare utilisation. Semi-structured, in-depth interviews were conducted with 23 men who had migrated from Mexico. Some men saw their migratory experience as empowering, both individually and within the couple context...

This paper considers how certain functions of online hook-up devices are participating in the emergence of new forms of sexual relation, new distributions of intimacy and new sexual arrangements. Though not without precedent, it argues that online hook-up devices generally act in gay culture as 'framing devices', framing sex as a 'no-strings' encounter via their default application. These frames are variously rejected, reconfigured, re-embedded or confounded by participants; they become subject to various forms of overflowing...

Twenty-five same-sex-attracted rural young Thai men were interviewed three times to investigate how their sexual subjectivity changed over an 18-month period after they completed high school and moved into a new life-phase. Many young men grew up with strong gender-based understandings of homosexuality, in which a masculine (top) partner is seen as complementing a feminine (bottom) partner. The discursive division between the masculine and feminine domains became increasingly blurred in the actual practice of dating, forcing the young men to develop new understandings of homosexuality and same-sex relations...

Technological change, particularly the growth of the Internet and smart phones, has increased the visibility of male escorts, expanded their client base and diversified the range of venues in which male sex work can take place. Specifically, the Internet has relocated some forms of male sex work away from the street and thereby increased market reach, visibility and access and the scope of sex work advertising. Using the online profiles of 257 male sex workers drawn from six of the largest websites advertising male sexual services in Australia, the role of the Internet in facilitating the normalisation of male sex work is discussed...
