Women Who Have More Male Friends Have More Sex In Their Relationships
Sperm competition is real.
Contrary to your first impression, it’s not some sort of he-man battle to the death, but rather the evolutionary urge to beat out potential rivals.
It’s the reason women with many male friends have more sex with their partners.
A study published in the Journal of Comparative Psychology reveals that, on a subconscious level, men see one another as reproductive competition.
So, even your best friends are in the same race to produce children that you are, biologically speaking.
Self-reported records, both sexual and social, from almost 400 heterosexual men showed a clear trend: If female girlfriends or wives had predominantly male coworkers or friends, sex was more frequent.
You’d never consciously think about beating out another man’s sperm, but you’re acting on the impulse, regardless.
There’s another key factor to the study, as well. Men had to believe their female partners were attractive to the men around them.
Unfortunately, the study didn’t record whether it was the male or female partner who most frequently began the sexual activity.
Todd K. Shackelford, one of the study’s lead authors, told Huffington Post he was inspired to complete the study after seeing similar behaviors happen in animals. He said,
…there’s a huge amount of nonhuman literature showing that male animals…become very interested in having sex with their partner when they see their partner interacting with other males.
They don’t even have to see them having sex with other males. It’s just the presence.
Although Shackelford’s study has limitations because the data was self-reported, he sees it as potentially beneficial for the medical community.
As the importance of sperm donation continues to grow, it’s important for doctors to understand how to achieve the best possible sample.
And on a practical level, women with large groups of guy friends can pat themselves on the backs.
