Since I missed the whole sex before marriage discussion, I'll post my opinion on the matter now...
First of all, I am Christian, and I do see sex as something more than just pleasure. But should it be saved for marriage? Sure, if that's what you want. But I believe that as long as you're in a committed relationship, having sex is perfectly fine. If you think about it, what's the difference between marriage and a committed relationship? A ceremony and a some legal papers, that's all. I don't see why you should have to wait for marriage if you already plan on spending the rest of your life together. Besides, some people can't get married. Andrew and I are a perfect example. We'd get married right this second if we could, but because the country we live in is so *censored.3.0*ed up, it's not legal for us to get married in the state we live in. If we would have waited until marriage to have sex, then we'd be waiting for a long time. But feel like, act like, and have the same vows as a married couple, so isn't that enough? To me, if you're both ready to spend the rest of your lives together, and you're truly in love, then sex is perfectly fine. If anything, it'll make your relationship even better. Of course, if you're a straight couple and not in the position to take care of kids, then you should be cautious and use protection until you're ready. (Luckily, I don't have to worry about that, lol.)
So, there. That's my opinion. If someone choses to wait until marriage, then you should respect their decision, not criticize them for it. But at the same side, people shouldn't be using the Bible to condemn people who have had sex before marriage. Yes, I'm Christian, but I know well enough that you can't take the Bible 100% literally, nor does everything it says apply to current times. I'm sure none of you believe eating shellfish is a sin punishable by death, right?
