In 2009, the National Survey of Sex and Behaviour asked 1,931 US adults aged 18 to 59 about their most recent sexual experiences.
They found a major orgasm gap between the genders, with men achieving orgasms 91% of the time they had sex, versus 64% of the time for women.
Interestingly enough, there was also a gap in the perception of orgasms. 85% of men said that their female partner had orgasmed – a significantly higher number than the percentage of women who confirmed that they actually had.
Which means that a lot of women are probably faking it.
The study also took a look at the types of sex the people engaged in, and noted which ones resulted in orgasm most frequently.
The data for men’s orgasms is on there, too, but given that men orgasm around 90% of the time regardless of type of sex, let’s just put that to one side.
To everyone’s shock and amazement, the number one sex act which reliably caused female orgasms was receiving anal sex, with 94% of women achieving orgasm when they partook in anal.
AKA the number one sex act men are always banging on about.
