Women are known for faking orgasms. But according to a 2016 study published in the journal Sexual and Relationship Therapy, men are just as guilty. In fact, a surprisingly high number of them are.

The study surveyed 230 men between the ages of 18 to 29 and found that 25 percent of them feigned orgasms in their current sexual relationship. It also found that the fakery most commonly occurred during vaginal sex.

The men stated that they’d usually feign an orgasm when the sex wasn’t going too great or if they just weren’t attracted to their partner. They also did it to not hurt a partner’s feelings or to improve the quality of the sexual encounter. Sometimes, it was because they were plain drunk.

This isn’t the only study to have pulled up this sort of information. A 2010 study published in The Journal of Sex Research surveyed 180 men, wherein 85 percent of them had penile-vaginal intercourse (PVI) experiences. 28 percent of the PVI-experienced participants reported pretending to orgasm.

Most faked it during PVI, but some also put on a show during oral sex, manual stimulation and phone sex.

The reasons given were that an orgasm was unlikely to happen, they wanted the sex to end, and that they didn’t want to hurt their partner’s feelings.

But seeing that a male orgasm involves semen, how on earth does a man fake an orgasm? Scroll the gallery to check out three possible ways.
