I'm going to a movie with this girl, and I like her (she's really pretty) and I think she might like me, so we might end up making out. But I'm really self conscious and worried that I might not be able to do a good job with her or might be too shy to, even though I really want to. I know a couple people like her, and want to go out with her, but should the opportunity arise for a hook up, I need to know what to do to overcome my shyness.

Also: Since a lot of people like her, I'm going to let her make a move if she wants to, but how do I seem, ermm... "inviting," but not slutty or like I'm dying for her to french me?
