News flash: men’s sperm prefer a one night stand.
A study has revealed that sex with new partners helps produce much better quality sperm.
The findings were discovered by the College of Wooster in the US. They tested the sperm of different men, asking the participants to masturbate to seven different porn movies over a few weeks, according to Men’s Health.
The first six movies featured the same actress, but the seventh starred someone totally different.
The participants reportedly climaxed twice as fast after watching the film with the new porn star, and their semen was higher in volume and more concentrated with healthy sperm.
The researchers aren’t totally sure why this is, but they believe it might be something to do with an evolutionary adaptation that gave men a stronger ability to impregnate multiple women and keep their bloodline strong.
So there you go, science says there’s a reason you finish so quick with a new partner.
