Researchers have discovered that oral sex is capable of preventing a woman from going astray in a relationship.
A research published in the Medical Daily draws this conclusion from a study of 243 men in long-term straight relationships.
The authors of the study tested to see if oral sex has a definitive evolutionary purpose for women, or whether it’s just harmless foreplay fun.
The study essentially found that women who are satisfied by their partners through oral sex are much less likely to resort to cheating.
It added that oral sex represents a key strategy for men to retain their women and keep them happy.
Medical Daily wrote: “The research showed that men who were most likely to report getting their partner to orgasm during oral sex were more likely to think their woman was sought after by other men.
“Therefore, the more eager men are to please partners believed to have better options, the more likely they may be to perform cunnilingus to keep their mates from cheating.”
But biologists also believe that there is another reason why women have evolved to enjoy oral sex so much.
Sex experts claim that when women have oral sex performed on them before intercourse, it can drastically improve sex quality.
Not only does this increase the amount of arousal a woman feels, but it naturally lubricates things, which makes for higher quality sex.
In fact, it turns out that women may actually have evolved to be more attracted to men who regularly perform oral sex on them.
