I am not ashamed to say I write fan fictions about my friends and the teachers they find attractive for them. We call one teacher 'Senpai' behind his back.
Shouldn't a teacher say something to the extent of "please don't ogle me, I am a teacher and you are students. That isn't going to happen." The guy could be into trees and small woodland creatures, it shouldn't matter.

I'm joking. Do what you want.
