Results from some new analyses as well as a selective review of the results of six empirical studies on a self-identified sample of sadomasochistically-oriented individuals 22 women and men with an emphasis on differences between gay and straight participants are presented. The gay male respondents seemed to be better educated, to hold white-collar occupations and to be more sadistically oriented. The gay male respondents became aware of their sadomasochistic preferences and had their first experiences at an older age. They showed a preference for leather outfits, anal intercourse, rimming, dildos, wrestling, special equipment and uniform scenes, and the straight male respondents for verbal humiliation, mask and blindfold, gags, rubber outfits, cane whipping, vaginal intercourse, cross dressing, and straitjackets, and different role plays except for uniform scenes. Four separate sexual themes were identified: hypermasculinity; administration and receiving of pain; physical restriction and psychological humiliation. Gay male participants showed a preference for hypermasculinity and straight men respondents for humiliation.
Few aspects of human biology are as complex—or politically fraught—as sexual orientation. Now, a new study claims to dispel the notion that a single gene or handful of genes make a person prone to same-sex behavior. The analysis, which examined the genomes of nearly half a million men and women, found that although genetics are certainly involved in who people choose to have sex with, there are no specific genetic predictors. Yet some researchers question whether the analysis, which looked at genes associated with sexual activity rather than attraction, can draw any real conclusions about sexual orientation. The handful of genetic studies conducted in the past few decades have looked at only a few hundred individuals at most—and almost exclusively men.
Between 2 and 11 percent of human adults report experiencing some homosexual feelings, though the figure varies widely depending on the survey.

Matthew Parris. Long-suffering Spectator readers deserve a seasonal break from yet another Remoaner diatribe from me. Instead, I turn to sex. There is little time left for me to write about sex as the thoughts of a septuagenarian on this subject I turn 70 this year may soon meet only a shudder. But I have a theory which I have the audacity to think important. My firm belief is that in trying to categorise sex, sexuality and — yes — even gender, the late 19th, 20th and early 21st centuries have taken the medical and social sciences down a massive blind alley. No such categories exist.
How do genes influence our sexuality? The question has long been fraught with controversy. An ambitious new study — the largest ever to analyze the genetics of same-sex sexual behavior — found that genetics does play a role, responsible for perhaps a third of the influence on whether someone has same-sex sex. The study of nearly half a million people, funded by the National Institutes of Health and other agencies, found differences in the genetic details of same-sex behavior in men and women. The research also suggests the genetics of same-sex sexual behavior shares some correlation with genes involved in some mental health issues and personality traits — although the authors said that overlap could simply reflect the stress of enduring societal prejudice. Even before its publication Thursday in the journal Science, the study has generated debate and concern, including within the renowned Broad Institute itself. Several scientists who are part of the L.
Homosexuality is romantic attraction, sexual attraction , or sexual behavior between members of the same sex or gender. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions. Along with bisexuality and heterosexuality , homosexuality is one of the three main categories of sexual orientation within the heterosexual—homosexual continuum. The most common terms for homosexual people are lesbian for females and gay for males, but gay also commonly refers to both homosexual females and males. The percentage of people who are gay or lesbian and the proportion of people who are in same-sex romantic relationships or have had same-sex sexual experiences are difficult for researchers to estimate reliably for a variety of reasons, including many gay and lesbian people not openly identifying as such due to prejudice or discrimination such as homophobia and heterosexism. Many gay and lesbian people are in committed same-sex relationships, though only in the s have census forms and political conditions facilitated their visibility and enumeration.
