They are discovering that "hooking up" is the easy part, but "unhooking" from the bonds of a sexual relationship can have serious consequences. A practical look into new scientific research showing how sexual activity causes the release of brain chemicals which then result in emotional bonding and a powerful desire to repeat the activity. This book will help parents and singles understand that "safe sex" isn't safe at all; that even if they are protected against STD's and pregnancy, they are still hurting themselves and their partner.
