HELP! Does he like me or is he just looking for a thrill?

My uncle always says "there's nothing more stupid than a teenage boy". Of course that's not true and is really just a joke, but there is some truth to the fact that teenage guys are pretty much always looking for a thrill. He was probably nervous and thinking he should make a move so he did that. It's annoying, and it's good you stopped it. Things should only move at a pace you are 100% comfortable with so don't let his eagerness influence you.
