How to become one of the guys?

Join clubs at your school and play sports aswell. Maybe join the baseball team in your area and you'll make a lot of guy friends that way. Also, maybe, at lunch, tell your friends you'll be sitting at a guys table for a couple days and then sit there. Just say: "Hi, do you mind if I sit here?" then share your common interests and eventually you'll be aquaintences. Then just start hanging out with them, like hunting or fishing, things you enjoy doing. I hope I could help. Good Luck. :)
