I'd just like to say that though I don't have a problem with pre-marital sex, I do agree with ender that there's too much preoccupation with sex in movies, TV, and music in general these days. If it adds to the story/content, then okay, I'm fine with it. If it's just there to titillate, though, then I don't see any need for it.
Now, with that out of the way, we can let this discussion die for good once and for all. ;-)
