Probably so. Good looks is highly valued by men, and therefore, good looking women have the pick of whomever they want.

Girls with confidence and self respect do, but a lot of good looking girls are actually quite insecure.
People generally either go for what they are or what they aren't. For example if a girls good looking but not so smart she will either go for looks or brains, depending on what she thinks of herself. I used to pull mostly very good looking but only above average intelligence girls or only above average looks but very intelligent girls. The latter were the more secure.
