How come many students become attracted to their teachers?

When I was a junior I was attracted to my u.s. history teacher. i did not really like him like him. i just think he is very cute. when he gets upset it kind of turns me on. i love the way he looks and I can’t stop looking at him.
I had a friend i use to talk to she told him that I think he is cute. he walk away from her and turn on me and just stare. I look away, because his reaction looks different then it use to be. he did not expected me to think like that. and he was surprise and uncomfortable but i could not help myself. he looked really attractive. he did not expect that from me because i was a shy student and quiet in his class. and my teacher was funny outgiong, exciting and a silly teacher and he was not my type at all. plus he loves sport, i don’t. I just love the way he looks.
I am a senior now and i don’t have his class no more , but sometimes i said i hi to him and i still like to look at him.

it not a big deal, it is just a little phase going through. i bet all students are like that with there teachers. get over it.
