I don't see anything wrong with being chaste until you find someone you feel you love, but I also want people to drop the taboo surrounding sex and start being mature about it. Our culture - at least that in the United States - doesn't consider sex something worth being open about, and this has done more to contribute to damage done by child molesters and sex-related disorders than any number of actual problems or people will.
There's obviously going to be an unspoken pressure if it's out in the open like this, but then again, the only people I personally know who consider sex in general in any way significant are the people who haven't had it. We all attach considerable significance to sex with someone you romantically care about, but none of us look at the act itself as in any way worthy of the pressure that motivated the TC to make this thread.
That said, I actively encourage people to find someone they like - not someone they love, or think they love, but someone nice, preferably with some experience, with whom there is no chance of any love-falling - and just have a good first time. I don't think sex is really worth it before college, but others disagree with me there. If this suggestion is resisted, no big deal, it's a personal choice and there's nothing wrong with making it.
EDIT: I'd also like to take this opportunity to say how high my eyebrows are rising over some of the elitist sexual conservatives in this thread.
FURTHER NOTE: Also note that I don't think "slut" should have a negative connotation. If a woman likes having sex, let her have sex. It's fun. It feels nice. It's sad that we as a culture have yet to embrace these things.
