Firstly, I think you guys are some sick fvcks for even wondering what under age women think. This isn't the highschool forum.
Secondly, looks matter at any age. I agree they become less important to women as they get older, but don't kid yourself into thinking they don't count. For any relationship to occur, you have to meet a woman's minimum standards on looks. If you're a great guy, you're rich, and have a wonderful personality, none of that will matter if you don't meet the "Minimum looks" standard.
