I was considered the radical Catholic for being sexually abstinent, being pro-life, and attending church weekly. This was especially true in college. So I figured that I was just about the only person, and pretty much the only Catholic, who was abstaining from sexual relations from marriage, and I resigned myself to being a lifelong virgin.
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.
