I just don't get it!

I have a lot of friends who are fashion models (people consider them very attractive), so your question although seemingly subjective, seems to be a pretty common phenomenon.
Many of the male models I know actually DO sometimes date girls that many would consider physically "not-as" attractive, for a variety of reasons. One of the main reasons is for the sex. These girls are often times cursed with the insecurity of having to feel that they are competing with a lot of other more attractive women, and so to compensate they tend to offer more tricks and services (so to speak).
I knew one girl who could suck a maraschino cherry through a coffee stirrer -- and that was just her warm-up routine! For many guys, this is an OPPORTUNITY that's simply too hard to pass up, especially when it won't cost them much time or money, and especially since the girl makes them feel like THEY are the ones who are being blessed by the guys company.
In contrast, the female models I know often times date guys who are generally considered "not-as" attractive, but for slightly different reasons. Usually because of the guys personality and social and/or financial status. And not surprisingly these types of guys also spend more time catering to women, as opposed to themselves, which is in stark contrast to their "better-looking" male counterparts.
But since "beauty is in the eye of the beholder", I guess it all works out in the end. (I think it's good when people get together for more than just looks, because otherwise we would eventually end up with just a really "good-looking" society -- that had very little else to offer :)2
