And it happens to one in 10 people, she added, probably unwittingly quoting 1940s sexologist Alfred Kinsey. Reading these numbers, I was curious whether the same ratio held true in gay and lesbian communities.Even Kinsey, though, did not find that 10 percent of people were gay. Unfortunately, I had to resort to much less scientific means.The male self-identified bisexuals in Chivers’s study reacted physically only to one gender or another, not both. When Bailey tried the same thing in his own lab, he found the same monosexuality.Most men who said they were bisexual seemed to be physically aroused only by other men.He found that about 10 percent of men, in his small sample, were exclusively homosexual. I got my hands on a marketing study prepared for in 2009.
Everything turned them on: men with men, women with women, men with women, and even bonobos with bonobos.Looking at the still images, their reactions to erect penises were significantly stronger than to female genitalia.None of this means, Chivers is quick to clarify, that straight women or gay women don’t really exist.In 2007, she ran the experiment again at the University of Toronto but this time included videos of solitary men and women masturbating or exercising naked.The second experiment confirmed the results of the first, with one difference: the lesbians in the study were more aroused by the solitary women and less by the solitary men.Being gay or lesbian just means being attracted to someone of the same sex.
