Lesbian women are 'significantly more likely' to orgasm than straight or bisexual females

Lesbian women are much more likely to orgasm during sexual activity than either straight or bisexual females, a new study has revealed.

Women also have less predictable and more varied orgasms than men, research looking at orgasm variation by a team at the Kinsley Institute has found.

Their study discovered that for women - but not men - how likely they are to orgasm varied depending on their sexual orientation, with bi-sexual women being the least likely to experience orgasms.

Researchers used an internet questionnaire to collect data from a total of 6,151 single men and women between the ages of 21 and 65 in the US.

The participants were asked about their gender, sexual orientation (heterosexual, gay/lesbian, bisexual), and what percentage of the time they reached orgasm during sex with a familiar partner.

The results from the survey revealed that, on average, men orgasm during sex with a familiar partner 85 per cent of the time, compared with 63 per cent of the time for women.

However, lesbian women had a much higher probability of orgasm (75 per cent) than either heterosexual women, at 62 per cent, or bisexual women, at 58 per cent.

The same variation was not found in men.

Researchers suggested this variation could be due to lesbian women being more comfortable and familiar with the female body, Metro reports.

“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.”

The study 'Variation in Orgasm Occurrence by Sexual Orientation in a Sample of US Singles' is published in the Journal Sexual Medicine.
