Why You Love Morning Sex — and How to Get More of It

There’s never a bad time to have sex, but science says it’s especially fun to mess around in the morning. How come?

For starters, you naturally build up testosterone overnight, which boosts your coital instincts in the A.M., says Tammy Nelson, Ph.D., a sex and relationship therapist and author of Getting the Sex You Want. You also have higher levels of vasopressin, a hormone that helps give you feelings of emotional attachment. Couple that with an erect penis, “and you may feel closer and more attached to your significant other in the morning,” Nelson says.
