When I was in my teens, like 16 or 17, just considering pre-marital sex made me feel extremely guilt-ridden and conflicted. On one hand, I'd abandoned my parents' religion, Christianity, and the conservative church I attended as a younger person, but I hadn't quite managed to get over what I'd been taught about virginity being one of the few valuable aspects of a girl, and the fear of being "ruined" for life if I ever had sex without having been a bride. Even when I got a bit older, I was concerned about not be respected or valued as a non-virgin, which kept me in line a long time. Now, I'm more clear-headed, I think. I wouldn't feel guilty if I had sex, but I personally desire a long-term, stable relationship, and I would feel guilty if I had a one-night stand or something. Moreover, I'm too concerned about possible pregnancy and disease to risk anything, but as far as guilt goes, I'm mostly over that.
