I'm fifteen and like my guy teacher?

So I'm fifteen (a guy) and like my science teacher. He has blonde hair (short/buzz cut) and the hottest, sexiest blue eyes :D! Idk what I should do because he almost flirts with me sometimes, like he compliments me on what I wear and he puts his hand on my shoulder and rubs it when he's standing next to me and talking to the class. The only thing is is that he has kids and he's married... oh and he's my teacher, haha. Any advice please? I really like him! :( Thanks!
