Pillow talk is good for your relationship.

Ever wonder why you (women especially) get chatty after sex? It’s probably due to a post-climax surge of the bonding hormone oxytocin.

Researchers at the University of Connecticut identified post-orgasmic oxytocin release as the main variable in those who engaged in pillow talk and those who did not. Women are more likely overall to engage in pillow talk, because it’s believed that testosterone may weaken the effects of oxytocin (and men are usually first to fall asleep).

These post-coital conversations are important social bonding tools and help increase trust and intimacy in relationships. In fact, they may be as important as what happens immediately before and during sex.
