Ever wondered why males and females always acted differently after sex? Turns out, there's some science to this. Scientists are examining the deeper motivations of post coital activities. And evolutionary psychology is here to the rescue! A new study from psychologists at Albright College noted that "few empirical studies have been devoted to exploring behaviors occurring immediately following sexual intercourse", which 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.
