Men and women act differently after sex because of evolution

The different behaviors of males and females in the bedroom has been ably investigated by decades of stand-up comics, but only now are scientists entering the fray to examine the deeper motivations of post-coital activities. Evolutionary psychology to the rescue!

Via the always great NCBI ROFL comes this new study from psychologists at Albright College. The researchers note that "few empirical studies have been devoted to exploring behaviors occurring immediately following sexual intercourse", and then explain how they set about rectifying that glaring oversight. They gave an online survey to 170 people, asking them to explain their preferred activities both before and after sex and in both short- and long-term relationships:

It was found that females were more likely than males to initiate and place greater importance on several behaviors related to intimacy and bonding following sex with long-term partners. Males were more likely to initiate kissing before sex, and females after sex. Intimate talk and kissing were rated by both sexes as more important before intercourse with a long-term partner, whereas cuddling and professing one's love was rated more important after sex. In a second set of more specific post-coital behaviors, females were more likely to engage in post-coital behaviors related to bonding with both short- and long-term partners, whereas males were more likely to engage in ones that were extrinsically rewarding or increased the likelihood of further coital acts.


That last bit is by far the nicest way of expressing that basic sentiment I've ever seen. I guess an evolutionary perspective really does make everything sound better.
