I guess i'm lucky, I'm 6'6", full thick hair, fairly big muscles (still a little skinny compared to most of you guys), a good amount of money for a college student, drive a beamer, and I'm an athlete but the girls are far from beating down my door - its all about game.
Some of my skinny, shorter, not as good looking friends have tons of game and get LOTS of girls but I guess I just wasn't born with it, maybe because I went to all boys schools from 7-12th grade. At clubs and bars girls are all over me at first but I always let them get away. And at parties or in the dining hall my buddies get tons of chicks because they know how to talk to them, so I don't think muscles or hair are the end all - the biggest factor is GAME.
