Basicaly, if you are 18+ and look at them wrong you will be getting along w/guys a lot better in the future. Go for someone your age, maybe a little older. 21 sounds good, she can buy for ya 🙂 btw, I'm 22 and used to try that 'bald' look. Really dude, grow some hair! Keep it short [under 2"] and it wont be hard to maintain.
