Is it normal to feel this way about a teacher?

I'm in grade 12 and I have this teacher. He's my English teacher, and I think he's the best thing in the world. Personally, I think he's cute as hell, although he's not the type that all the girls are after. And he's funny and sweet and he LOVES his job. The way he talks about himself in class, too, I can tell that we have a lot in common. We like the same music, we like sports, we think about a lot of things the same way. Just by the things he says, I can tell.
I find myself fascinated with him. I can't wait to go to English every day (English has always been my favourite subject ANYWAY, right through school, but even moreso this year). If I see him in the halls, I get really nervous and I try to make myself occupied with something else, because I'm not sure what shows on my face when I see him. I have to walk past his classroom every morning to get to my locker, and I find myself involuntarily glance in there every single time I pass, just to get a glimpse of him.
And I keep having dreams about him. The whole kicker in this story is, though, that I have not, honest to God, once had a sexual thought/dream/fantasy about him at all. And that's the honest truth.
That's what I don't get. I would say that this was a crush, but I thought that, for it to be a crush, I would have to have at least SOME of those kinds of thoughts, even if they were random and against my own will.
But my dreams are all about more hanging out with him or something like that. Not sleeping with him. I have no desires to have sex with him or make out with him or marry him or anything. I just have this fascination with him, like I want to be around him all the time. It's weird and it's driving me crazy. Does anyone know if this is normal?
