If you are a religious person and your particular religion frowns upon sexual relations before marriage, did you have pre-marital sex anyway?

I put this one in General, because I just want to know if any of you religious folks had pre-marital sex and what was your reasoning. If you did, do you still feel OK with that decision, or do you wish that you had not had pre-marital sex, and if so, why?

I’m not religious and I think that pre-marital sex is a prerequisite for marriage, but that’s just me.

Let’s try to keep this discussion polite.
