A member asked:

Why do we feel sleepy after having sex?

A doctor has provided 1 answer

Endorphins: Orgasm releases endorphins, which have a relaxing effect on the body. Plus sex is exercise, at least a little. There's also the psychological effect of physical closeness--feeling warm, comfortable, embraced and safely tucked away that lends itself to falling asleep.
