I'm a female, but I had a number of crushes. My high school business law and then marketing teacher was probably my biggest crush. The things I did to impress him.
Let's see, then there were the 2 history teachers...yumma! One of them was the mens lacrosse coach, so it didn't hurt that I managed the men's lax team. The other wasn't my teacher, but I made sure to join my friends in their class for regent prep classes. (I recall students telling me he played for the Jets at one time, but I never confirmed it.)
I definitely had more of a thing for teachers than peers, probably because they were taller than my classmates.
I also had teachers who had a thing for me...but that's a different thread.
