Lesbians are more likely to have orgasms than straight women, according to new research.

The study, published by the Journal of Sexual Medicine, found that lesbians report experiencing orgasm during sex 75% of the time with a familiar partner – up from 62% for straight women.

Bisexual women are the least likely to experience orgasm, with just 58% experiencing regular orgasm.

Despite the variations among women, a similar percentage of gay, bisexual and straight men experienced orgasm during sex, with 85.1% doing so.

The study’s authors wrote: “One possible explanation is that lesbian women are more comfortable and familiar with the female body and thus, on average, are better able to induce orgasm in their female partner.

“Findings from this large dataset of US singles suggest that women, regardless of sexual orientation, have less predictable, more varied orgasm experiences than do men and that for women, but not men, the likelihood of orgasm varies with sexual orientation.

“These findings demonstrate the need for further investigations into the comparative sexual experiences and sexual health outcomes of sexual minorities.”

More than 6,500 people between the ages of 21 and 65 took part in the study, conducted by Indiana University.
