In my opinion, the whole moralistic chastity thing is unnatural with typical humans. Of course, as a few of you have said, it is required for a functioning society (well, maybe not required but it's desirable). Experience tells me that females who are unchaste are that way due to their own impulses and not because they ignored their christian upbringing. Christianity doesn't do a very good job at abating the "sleeping around" issue that seems to be so common. Divorce rates are high for christians as well, and many people in general will often delude themselves with personal excuses as to why they did something that's considered negative. To sum up my rambling, I think that the discipline required for these relationships (society pushes them, why?) is lacking in many folks. As someone mentioned earlier, the media represents (literature as well) an idiotic, ideological side of relationships that can turn something beautiful like sex/companionship into something vile. I know several women who look for "the one" while continuously whining about a boyfriend's flaws to their friends. And yet, they love to get into relationships for that selfish satisfaction; pleasing the partner is secondhand. I see that as a large issue as well....
