A recent article (see below) analyses 52,000 questionaire responses from men and women of varying sexual orientation. The focus was on the frequency of orgasm during sex. There were some disturbing results. Some were no surprise; for example, heterosexual women having sex with a male partner have the lowest rate of orgasms. In contrast were results about what increases the rate of orgasm in women, and the mistaken beliefs a significant number of men have (From the Guardian):
“About 30% of men actually think that intercourse is the best way for women to have orgasm, and that is sort of a tragic figure because it couldn’t be more incorrect,” said co-author of the research Elisabeth Lloyd, a professor of biology at Indiana University and author of The Case of the Female Orgasm.
According to the research, only 35% of heterosexual women always or usually orgasm during vaginal sex alone, with 44% saying they rarely or never did. By contrast, 80% of heterosexual women and 91% of lesbians always or usually orgasm with a combination of genital stimulation, deep kissing and oral sex – but without vaginal sex. “To say that there needs to be some education I think is an understatement,” said Lloyd.
Elisabeth Lloyd is also a very distinguished philosopher.
