I often hear this question, spoken with anguish, in my office. It's not the real question being asked, but it's the one that's easiest to pose. The short answer is "no." You can't take it back so listen to yourself, think about what kind of experience you would really like, and don't worry how many virgins are wandering around campus.
Have a great "first time," have a great future sex life? Probably not. But a new study claims that a satisfying loss-of-virginity experience could predict sexual satisfaction down the road.
