Oxytocin: The Cozy-Up Hormone
When someone touches you, you get a wave of oxytocin. We all do. Oxytocin warms our attachments in the family and provides a surge of pleasure released before and during orgasm. It's present during exercise, childbirth, and breast-feeding, and triggers an orgasm by making the nerves more sensitive to pleasure. It also explains why we feel so cozy together after sex--even with strangers.
