I never get adults who have sex with teenagers. Yes, some of them are attractive, but they are too irritating for anyone but other teenagers to be involved with them romantically.
I do remember in junior high how the boys would react to an attractive female teacher in her 20s. They would be very flirtatious and inappropriate. I remember one who used to scratch them with very sharp nails whenever they would say something inappropriate to her.
I think that's called assault and would get her dismissed these days ,freedom of speech don't you know ?
