New research from the University of Leeds suggests that sperm coated with “sex peptides” may, when male fruit flies mate with female fruit flies, cause the females to give up their afternoon siestas in favor of so-called “housework” - a bunch of foraging and other important fruit fly work. And the females may do this for as long as 8 days post-mating! That’s right- 8 DAYS!!! How fascinating.
However: Human Ladies, please don’t let this idea creep into your own bedroom and kitchen. Thus far I know of no evidence that suggests that human sperm encourages the same gender division in women – it’s probably just outdated ideas that let him sit on the sofa while you get out the Dyson. In fact, we know from quite a few studies that couples who share responsibilities and who are more equal in their relationship tend to have higher rates of sexual satisfaction, something I discuss quite a bit in my book Because It Feels Good. After all, I want you – yes, you! – to have great, satisfying, hungry-like-a-wolf sex too. And it’s totally possible: it just takes courage, a few tips and a willingness from you and your honey bee. Or fruit fly. Whatever.
