like everyone else said, be yourself, man. just be friends. if you guys end up being together cuz of what the other person 'has to offer', its not gonna last long. good relationships are built on being good friends. cuz when you guys are gettin older and the physical aspects start to fade, it'll be the friendship that lasts.
of course im talkin like you want this girl to be it
just be honest and dont try too hard to cover up your 'weaknesses'. if they cant get down w/ who you really are, then you have no reason to be w/ that person for however long. its a waste of time
