According to a recent study by evolutionary psychologists at the University of Michigan and Albright College in Pennsylvania, the tendency to fall asleep first after sex is associated with greater partner desire for bonding and affection.
“The mo
re one’s partner was likely to fall asleep after sex, the stronger the desire for bonding,” explains Daniel Kruger, research fellow at the University of Michigan, and lead author of the study.
The study, published in December in the Journal of Social, Evolutionary, and Cultural Psychology, examined 456 participants, who completed anonymous online surveys assessing experiences and desires with one’s partner after sex. Participants then indicated “who falls asleep after sex?” and “who falls asleep first when going to bed not after sex?”
Participants whose partners nodded off immediately after sex had stronger desires for post-coital cuddling and chatting.
The study also looked at who were more likely – men or women – to fall asleep first. Despite the common stereotype, the researchers did not find it more common for men to fall asleep first after sex. Women, however, were more likely to fall asleep first when sex hadn’t taken place.
“Perhaps men stay awake longer as an artifact of mate guarding – making sure the woman doesn’t leave them for another partner,” says Hughes. “Men may also stay awake longer in an attempt to entice their partner into having sex.”
Post-sex etiquette
1. When the climax is reached and ended, do not rush to do anything but stay close to your partner.
2. You can softly mention how much you enjoyed what was done, and how good you now feel. Even if it’s necessary, wait a few moments before leaving the bed for the bathroom.
3. Maintain body contact.
4. Enjoy more intimacy by embracing your partner and give (and receive) more mutual caresses.
5. Don’t immediately check your mobile phone for messages or missed calls.
