If men want to stop their girlfriends cheating they should perform a certain sex act, according to scientists.
A new study found that giving oral sex is proven to stop ladies from straying – and the more they get the less likely they are to play away.
Researchers at Oakland University quizzed 243 heterosexual men in relationships to see whether they performed cunnilingus to make their partner feel more satisfied in the sack.
They found that men are more likely to perform oral sex if they think their partner is attractive and at risk of being seduced by another man.
Obviously keeping your partner happy isn’t just down to giving her great oral sex, but according to scientists it helps alot.
The news comes after a recent study revealed there’s an “oral sex gap” between women giving and receiving.
According to a new survey called “Was it good for you too?” men are more likely to receive oral sex but not return the favour.
The study found that 63% of lads said they’d received oral during their last sexual encounter compared to just 44% of women.
Researchers also discovered that more ladies (59%) than men (52%) reported performing oral sex on their partner.
But it’s not necessarily down to guys being selfish between the sheets.
The authors reckon it actually comes down to women feeling sensitive about being “unclean” down there.
They said: “Women indicated that they would not be comfortable receiving oral sex from a partner unless they had just finished showering/bathing, due to feelings of self-consciousness about the way they smelled.
“This interfered with their ability to focus on their own pleasure and led to feelings of anxiety when receiving oral sex was a possibility.”
