I think I love him

So there is a guy at school, and he's really hot. I'm developing a major crush on him but problem is, I have never ever spoken to him or been in any of his classes. Some of my friends know him and say he's really funny and nice. I don't know what to do, because now I think he knows that I like him! Argh help me! Oh, and by the way... I've never had a boyfriend! *Teehee*
