I'm no good with girls... I always seem to say the wrong thing.
You just need to be calm, relaxed, nice, polite and all that jazz. Look, there's a nice girl over there. Just go over there and calmly and politely ask her if she would want to go to dinner some time.
Hey I can't help but notice that you look pretty damn hot why don't we go and have sex and you can suck my BIG HARD COCK!
