Dude, be grateful for what you've got. A few years from now your friends are all going to be fat and ugly, and you'll still be lean. You are normal. You have the body you're supposed to have. People with thin bodies live healthier, longer lives.If you want to have more muscles, lift weights, but don't try to put on extra pounds just to look like everybody else.You don't have to have the same body type as other people to be attractive. Do you think Leonardo DiCapprio has any trouble getting women?Don't waste your youth wishing you had someone else's body. Enjoy the body you've got. If you don't, when you get older, you'll wish you had.Thin is in!
