I'm in LOVE with my teacher! What should I do?

My teacher is young, he's tall and extremly HOT! And once I had a low croped top on and I went to 'Ask him a question' And I leaned down on his desk and he stared down my shirt!! I almost died!! Even though that was kinda what I wanted him to do! One day after school, I saw him in the parking lot at Wal-Mart, and I told him if he ever needs to see me in 'Pravate' I will be happy to see him. My friends call me a skank and stuff, but I dont think I am! Please help me!! Shoudl I just tell him I LOVE him and we can start dating. But I don't want him to get fired because I look forward to seeing him everyday. I just hope he likes me back... I mean I'm really pretty and I'm 32c, and lot's of guys in my grade like me. But I like my teacher!! WHAT SHOUDL I DOO??
