Men usually have this suspicion for ladies that tend to have lots of males as their friend and this study might just make some men say ‘I thought as much’; but not so fast fellas, it isn’t what you think.
A study from Oakland University, recently published in the Journal of Comparative Psychology, found that women with a lot of men in their life — like friends or co-workers — have more sex with their boyfriends compared with couples in which the female partner has fewer male influences.
A girl surrounded by men gets more sex and scientists say it comes down to a concept called sperm competition psychology.
The male sperm is said to be competitive and if sperm from two different males ends up inside the same female, the little guys will actually fight each other to the death in order to fertilise first.
According to Fusion, this biological desire to fight off other sperm translates to the dating world as a psychological desire to fight off other men known as “sperm competition psychology”.
“Men are sexually aroused by their partner when they estimate a greater likelihood of partner infidelity,” Michael Pham of Oakland University told Fusion.
“If they estimate a greater likelihood of their partner’s infidelity, then they may (subconsciously) want to have sex with her to enter into sperm competition,” says Pham.
Pham says that sperm competition occurs at a sub-conscious level and the same behaviour is seen in various animals too, as it’s just an old rivalry thing.
“This does not mean that men want their partner to cheat on them. Rather, this means that if they estimate a greater likelihood of their partner’s infidelity, then they may (subconsciously) want to have sex with her to enter into sperm competition.” He said.
So when a girl has lots of male friends or colleagues, the more sex her partner will want to have with her – especially if he believes men find his partner attractive.
