Among single adults in the U.S., women, regardless of sexual orientation, have less predictable, more varied orgasm experiences than do men, new research indicates. The study revealed that men experience orgasm during sexual activity with a familiar partner 85% of the time on average, compared with 63% of the time for women.
The Journal of Sexual Medicine study also found that for women, but not men, the likelihood of orgasm varies with sexual orientation, with lesbian women having a significantly higher probability of orgasm than either heterosexual or bisexual women (75%, 62%, and 58%, respectively).
