Getting back to the thread title: one reason is that if a girl is more physically attractive, any bloke who generally doesn't have much luck with girls anyway will tend to assume she's already in a relationship. That's the whole point of attractiveness; you don't usually get to the finer points - sense of humour, common interests, intelligence - until you've established a mutual attraction...shallow but sadly true.

Of course, it works both ways; sometimes a beautiful girl will have trouble finding the right bloke because she's beautiful - blokes think 'nah, she's gorgeous, I've no chance', so beauty can be a double-edged sword. As a corollary, the 'less' attractive girls (and, BTW, I agree with Robert Heinlein: there are no unattractive ladies; there are only some who look better than others, assuming we're talking purely about physical attractiveness) concentrate more on personal qualities and attributes, viz. the finer points I mentioned. This can result in a deeper relationship, on both sides, so that's one answer to the question...but in truth it takes a great deal of moxie to ask any girl out. In fact I can't remember the last time I did. Not that I lack the courage per se, but because I'm on a crappy shift and don't get much opportunity.
