Understanding how men who have sex with men (MSM) identify with sexual role labels such as Top, Bottom, or Versatile offers descriptive insights into how sexuality, identity, and self-presentation of masculinity intersect on dating platforms. Drawing on cross-sectional data from 141,156 active users of the global gay dating app Surge, a new study describes age-based […]
Sexual Synesthesia
Synesthesia is a neurological condition that causes the senses to link and merge. People with this condition may hear colors or taste words and more than 4% of people have some form of synesthesia. People who experience sexual synesthesia, or sexual synesthetes, may have involuntary visions of color, shapes, patterns, or even full-blown scenes when […]
Students Shedding Pubic Hair
Researchers from Indiana University studied a total of 3,139 students (about evenly divided between males and females), who completed the online Campus Sexual Health Survey, to assess their habits of genital grooming. Over 97% of students had shaved or trimmed pubic hair at some point in their life, with an average starting age of 15.5 years. […]
Broadening Our View of Autoeroticism
Sexual self-stimulation takes more forms than just stroking one’s genitals, as a recent weighted sample of 3,423 American adults shows. Some people arouse themselves by reading erotica or touching different parts of their body, or merely through personal fantasies; orgasm can also be induced by “syntribation,” which involves flexing pelvic or thigh muscles. Although little […]
Study: Mental Health Disparities Among Sexual Minorities Are Due to Family Background, Not Stigma
Compared with the heterosexual population, LGBT people today score lower on key mental health indices. Current scholarship relies on Sexual Minority Stress Theory (SMST) to explain the disparity as resulting from stigma and discrimination. Historically informed scholars question this approach, pointing to the ground-breaking work of UCLA psychologist Evelyn Hooker, who showed in the 1950s […]
Most Penis Size Obsession is Psychological

A team of three women from the University of New Brunswick has studied the use of sex toys in 100 mainstream heterosexual pornographic videos.

World Cup and Babies
Do major sporting events, such as this year’s World Cup, influence the sexual behavior of fans and cause a significant change in local birth rates and sex ratios? A review of 4 different studies indicates that the answer is “maybe”. These studies looked at birth rates and/or sex ratios in live births 9 months after […]
Penile Plethysmography Ruled Inadmissible
In a unanimous decision, the Supreme Court of South Carolina has ruled that penile plethysmography lacks sufficient scientific support to be used as a reliable indicator of likely future recidivism in sex offenders. Among its many flaws, the court cited a lack of standardized metrics among different labs, poor test-retest consistency, inconsistent test materials, and […]
“Cumdump” as a Sexual Identity
“Cumdump” is a slang term in the gay community for a man whose primary sexual goal is to receive ejaculates from multiple partners within a limited period, either serially or at a group sex party; the concept is most often framed by scholars through risk-based and pathologizing discourses, but the development of PrEP and effective […]
