@lizards : You do realise your entire emotional outlook is rather pathetic, and, instead of being rightfully ashamed, you are actually proud of that? Pray excuse me for being bemused, but I wasn't aware that people were wont to be proud of their failures, particularly in so base an area.
Oh, and it's a documented fact that one-night stands invariably produce bad sex. It's awkward, there's no care or attention given or recieved, and in the end you're lucky is either of you gets an orgasm before the whole thing comes to a messy, cold-sweaty and extremely ugly end. Wheras in a relationship, the sex might start out bad, but it invariably gets better. You learn what she likes, you experiment, try new things, but above all, that level of emotional connection, and comfortable, easy intimacy will make things better. So, yes, lizard, you are rather pathetic.
@Maxthereaper : You know, you can be frighteningly perceptive at times.
On-topic: Look, it's simple. Monogamous relationships are, probably, the way to go. I don't care about the genetic link, and I don't care about 'open' relationships - the reason humans developed the monogamous relationship was because it is the most stable form of long-term relationship.
