Representations of consensual sadomasochism range from the dark, seedy undergrounds of crime thrillers to the fetishized pornographic images of sitcoms and erotica. In this pathbreaking book, ethnographer Staci Newmahr delves into the social space of a public, pansexual SM community to understand sadomasochism from the inside out. Based on four years of in-depth and immersive participant observation, she juxtaposes her experiences in the field with the life stories of community members, providing a richly detailed portrait of SM as a social space in which experiences of \"violence\" intersect with experiences of the erotic. She shows that SM is a recreational and deeply gendered risk-taking endeavor, through which participants negotiate boundaries between chaos and order. Playing on the Edge challenges our assumptions about sadomasochism, sexuality, eroticism, and emotional experience, exploring what we mean by intimacy, and how, exactly, we achieve it.

Early Andean historiography reveals a subaltern history of indigenous gender and sexuality that saw masculinity and femininity not as essential absolutes. Third-gender ritualists, Ipas, mediated between the masculine and feminine spheres of culture in important ceremonies and were recorded in fragments of myths and transcribed oral accounts. Ritual performance by cross-dressed men symbolically created a third space of mediation that invoked the mythic androgyne of the pre-Hispanic Andes. The missionaries and civil authorities colonizing the Andes deemed these performances transgressive and sodomitical. In this book, Michael J. Horswell examines alternative gender and sexuality in the colonial Andean world, and uses the concept of the third gender to reconsider some fundamental paradigms of Andean culture. By deconstructing what literary tropes of sexuality reveal about Andean pre-Hispanic and colonial indigenous culture, he provides an alternative history and interpretation of the much-maligned aboriginal subjects the Spanish often referred to as “sodomites.” Horswell traces the origin of the dominant tropes of masculinist sexuality from canonical medieval texts to early modern Spanish secular and moralist literature produced in the context of material persecution of effeminates and sodomites in Spain. These values traveled to the Andes and were used as powerful rhetorical weapons in the struggle to justify the conquest of the Incas.

In the past decade, researchers have begun to study the sexual functioning of typical older persons. This review summarizes literature on the sexuality of men and women over age 50 as researched by social and health scientists. Research on the relationship of biological factors (changes accompanying aging), health (physical, mental, and medication use), psychological factors (attitudes, information about sex), relationship factors (status, satisfaction), and sexual functioning (desire, dysfunctions, treatment) to sexual behavior is reviewed. The review suggests that (a) men and women remain sexually active into their 70s and 80s, (b) aging-related physical changes do not necessarily lead to decline in sexual functioning, and (c) good physical and mental health, positive attitudes toward sex in later life, and access to a healthy partner are associated with continued sexual activity. In turn, regular sexual expression is associated with good physical and mental health. Progress in understanding later life sexuality requires development of comprehensive theoretical models, a broad focus on intimacy, attention to measures and samples, and research on couples. Progress in understanding is especially important, given the aging of populations.

From about seven children per woman in 1960, the fertility rate in Mexico has dropped to about 2.6. Such changes are part of a larger transformation explored in this book, a richly detailed ethnographic study of generational and migration-related redefinitions of gender, marriage, and sexuality in rural Mexico and among Mexicans in Atlanta.

Objectives To examine the relation between health and several dimensions of sexuality and to estimate years of sexually active life across sex and health groups in middle aged and older adults.Design Cross sectional study.Setting Two samples representative of the US population: MIDUS (the national survey of midlife development in the United States, 1995-6) and NSHAP (the national social life, health and ageing project, 2005-6).Participants 3032 adults aged 25 to 74 (1561 women, 1471 men) from the midlife cohort (MIDUS) and 3005 adults aged 57 to 85 (1550 women, 1455 men) from the later life cohort (NSHAP).Main outcome measures Sexual activity, quality of sexual life, interest in sex, and average remaining years of sexually active life, referred to as sexually active life expectancy.Results Overall, men were more likely than women to be sexually active, report a good quality sex life, and be interested in sex. These gender differences increased with age and were greatest among the 75 to 85 year old group: 38.9% of men compared with 16.8% of women were sexually active, 70.8% versus 50.9% of those who were sexually active had a good quality sex life, and 41.2% versus 11.4% were interested in sex. Men and women reporting very good or excellent health were more likely to be sexually active compared with their peers in poor or fair health: age adjusted odds ratio 2.2 (P<0.01) for men and 1.6 (P<0.05) for women in the midlife study and 4.6 (P<0.001) for men and 2.8 (P<0.001) for women in the later life study. Among sexually active people, good health was also significantly associated with frequent sex (once or more weekly) in men (adjusted odds ratio 1.6 to 2.1), with a good quality sex life among men and women in the midlife cohort (adjusted odds ratio 1.7), and with interest in sex. People in very good or excellent health were 1.5 to 1.8 times more likely to report an interest in sex than those in poorer health. At age 30, sexually active life expectancy was 34.7 years for men and 30.7 years for women compared with 14.9 to 15.3 years for men and 10.6 years for women at age 55. This gender disparity attenuated for people with a spouse or other intimate partner. At age 55, men in very good or excellent health on average gained 5-7 years of sexually active life compared with their peers in poor or fair health. Women in very good or excellent health gained 3-6 years compared with women in poor or fair health.Conclusion Sexual activity, good quality sexual life, and interest in sex were higher for men than for women and this gender gap widened with age. Sexual activity, quality of sexual life, and interest in sex were positively associated with health in middle age and later life. Sexually active life expectancy was longer for men, but men lost more years of sexually active life as a result of poor health than women.

Why is the rate of teen childbearing is so unusually high in the United States as a whole, and in some U.S. states in particular? U.S. teens are two and a half times as likely to give birth as compared to teens in Canada, around four times as likely as teens in Germany or Norway, and almost ten times as likely as teens in Switzerland. A teenage girl in Mississippi is four times more likely to give birth than a teenage girl in New Hampshire—and 15 times more likely to give birth as a teen compared to a teenage girl in Switzerland. We examine teen birth rates alongside pregnancy, abortion, and “shotgun” marriage rates as well as the antecedent behaviors of sexual activity and contraceptive use. We demonstrate that variation in income inequality across U.S. states and developed countries can explain a sizable share of the geographic variation in teen childbearing. Our reading of the totality of evidence leads us to conclude that being on a low economic trajectory in life leads many teenage girls to have children while they are young and unmarried. Teen childbearing is explained by the low economic trajectory but is not an additional cause of later difficulties in life. Surprisingly, teen birth itself does not appear to have much direct economic consequence. Our view is that teen childbearing is so high in the United States because of underlying social and economic problems. It reflects a decision among a set of girls to “drop-out” of the economic mainstream; they choose nonmarital motherhood at a young age instead of investing in their own economic progress because they feel they have little chance of advancement.

Sexual satisfaction is an important indicator of sexual health and is strongly associated with relationship satisfaction. However, research exploring lay definitions of sexual satisfaction has been scarce. We present thematic analysis of written responses of 449 women and 311 men to the question \"How would you define sexual satisfaction?\" The participants were heterosexual individuals with a mean age of 36.05 years (SD = 8.34) involved in a committed exclusive relationship. In this exploratory study, two main themes were identified: personal sexual well-being and dyadic processes. The first theme focuses on the positive aspects of individual sexual experience, such as pleasure, positive feelings, arousal, sexual openness, and orgasm. The second theme emphasizes relational dimensions, such as mutuality, romance, expression of feelings, creativity, acting out desires, and frequency of sexual activity. Our results highlight that mutual pleasure is a crucial component of sexual satisfaction and that sexual satisfaction derives from positive sexual experiences and not from the absence of conflict or dysfunction. The findings support definitions and models of sexual satisfaction that focus on positive sexual outcomes and the use of measures that incorporate items linked to personal and dyadic sexual rewards for both men and women.

The Dual Control Model proposes that sexual responses involve an interaction between sexual excitatory and sexual inhibitory processes. The model further postulates that individuals vary in their propensity for both sexual excitation and sexual inhibition, and that such variations help us to understand much of the variability in human sexuality. The development of psychometrically validated instruments for measuring such propensities for men (Sexual Inhibition/Sexual Excitation Scales) and for women (Sexual Excitation/Sexual Inhibition Inventory for Women) is described. These measures show close to normal variability in both men and women, supporting the concept that \"normal\" levels of inhibition proneness are adaptive. The relevance of the model to sexual development, sexual desire, the effects of aging, sexual identity, and the relation between mood and sexuality are discussed, and the available evidence is reviewed. Particular attention is paid to gender differences and similarities in propensities for sexual excitation and inhibition. Research findings related to sexual problems, high-risk sexual behavior, and the relevance of this model to clinical management of such problems are also summarized. Last, ideas for future use and further development of the Dual Control Model are considered.

In this study, men 65 years of age or older with low serum testosterone and symptoms of hypoandrogenism received testosterone or placebo for a year. Testosterone had a moderate benefit in sexual function and some benefit in mood but no benefit in vitality or walking distance. Testosterone concentrations in men decrease with increasing age. 1 , 2 Many symptoms and conditions similar to those that are caused by low testosterone levels in men with pituitary or testicular disease become more common with increasing age. Such symptoms include decreases in mobility, sexual function, and energy. These parallels suggest that the lower testosterone levels in older men may contribute to these conditions. Previous trials of testosterone treatment in men 65 years of age or older, however, have yielded equivocal results. Although testosterone treatment consistently increased muscle mass and decreased fat mass, 3 , 4 effects on physical performance, 3 , 5 , 6 sexual function, . . .

Background Little is known about the prevalence and correlates of intimate partner violence (IPV) among gay, bisexual and other men who have sex with men (GBMSM) in the UK. The aim of this study was to investigate the prevalence of IPV, associations of socio-economic and psychosocial factors with IPV, and the association of IPV with depression and sexual behaviour, among GBMSM in the PROUD trial of pre-exposure prophylaxis (PrEP). Methods PROUD enrolled 544 HIV-negative participants in England from 2012 to 2014; participants were randomised to immediate or deferred PrEP. This analysis included 436 GBMSM who had IPV data at month-12 and/or 24. Prevalence of IPV victimization and perpetration (lifetime, and in the past year) was assessed at these time-points. Generalized estimating equations were used to investigate associations with IPV, using pooled data from both time-points. Results At month-12 ( N  = 410), 44.9% of men reported ever being a victim of IPV, 15.6% in the last year, and 19.5% reported ever perpetrating IPV, 7.8% in the last year. At month-24 ( N  = 333), the corresponding prevalence was 40.2 and 14.7% for lifetime and past year IPV victimization and 18.0 and 6.9% for lifetime and past year IPV perpetration. IPV prevalence did not differ by randomised arm. Men reporting internalized homophobia and sexualized drug use were more likely to report IPV. Lifetime and last year experience of IPV victimization and perpetration were strongly associated with depressive symptoms (PHQ-9 ≥ 10) (adjusted for socio-demographics: lifetime IPV victimization PR 2.57 [95% CI: 1.71, 3.86]; past year IPV victimization PR 2.93 [95% CI: 1.96, 4.40]; lifetime IPV perpetration PR 2.87 [95% CI: 1.91, 4.32]; past year IPV perpetration PR 3.47 [95% CI: 2.13, 5.64], p  < 0.001 for all); IPV was not consistently associated with measures of condomless anal sex or high partner numbers. Conclusions GBMSM at high-risk of HIV who are seeking/taking PrEP may experience a high burden of IPV, which may be linked to depression. Training on awareness of and enquiry for IPV among GBMSM in sexual health clinics is recommended. Trial registration ClinicalTrials.gov identifier: NCT02065986 .
