And it's rather obvious and common.
My single high school biology teacher was also a muscle-head who worked out on the side and had a very high opinion of himself. Some of the underage teen girls were ga-ga for him, despite some of the stoner "bad kids" breaking into his store room and having an unfortunate human "FETUS FIGHT" by opening some jars and throwing the contents at one another when they were left alone in the classroom by the substitute teacher who quit without telling the administration. I think they got expelled, but I don't remember.
Anyway, he wasn't into underage girls himself. He could have made some serious fantasies come true without any tattle-tails if he had been. I am fairly sure of that. Whether that sort of encounter is something good or bad is another topic entirely. I've never been a fan of physical intimacy where one person has current authority and power over another.
