First, I want to say how awesome it is that so many of y'all have waited/are waiting/are practicing abstinence. Maintaining sexual purity in this day and age is a super difficult thing to do, for the reasons that have been mentioned in this thread, and also due to the fact that we live in a sex-saturated society (say that three times fast). If you've felt the pressure to give up your virginity and stayed strong, that's a big deal. If you've given in at some point but changed course and are now abstaining, that's a big deal. I would give ya'll two thumbs up, but I haven't got any thumbs (ok, I do, but that seems so cheesy so I'll just...not).
The second thing I want to say isn't directed at anyone who's posted in this thread, but is more just a thing I've noticed about people I've personally known-
It seems like sometimes people end up turning their virginity into a type of idol, a thing that makes them better or above others, and a thing that they place such a huge amount of importance on that it's like they can't see around their own ego about it to the real reason they decided to remain pure in the first place- Jesus. There was one girl in particular that I grew up going to church with; by the time we were 18, 19, 20...she was still a virgin, and I wasn't. It was a thing she often threw in my face when we'd argue- she'd say things like "Fine, I gossip. So? At least I don't sleep around." (which was unfair because I wasn't sleeping around, but hey, once you lose your virginity, apparently your entire reputation is up for speculation and ridicule).
Anyway, my point is, it's wonderful to wait until you're married to have sex. It's the right choice. It's difficult, and therefore a commendable thing. But it seems like it also can result in a lot of pride and arrogance for some people.
