Another problem is that deviant behavior has become more acceptable--now that Western Civilization is in an advanced stage of decadence--and those inclined toward it are less inclined to stay in the closet.
However such behavior was going on when I was in school decades ago.
Pedophiles were there, but they were careful to stay deep in the closet.
There was a female teacher who, it was rumored, had a prolonged affair with a young teen-age male student, who was older than me. Once in a movie with my mother, we happened to sit behind this teacher and the boy. I knew who they were, but my mother didn't. They began to snuggle--in today's jargon "inappropriately". My mother was shocked--nudged me--and pointed for me to see--shocked that anyone would behave like that in a movie theatre. I whispered to her their names, told her that the woman was one of the school teachers and the boy a student. My mother was shocked into disbelief! She was completely dumbfounded. She did nothing other than gasp in disbelief. Years later I mentioned the incident to her occasionally--just to horrify her. She was still stunned. (My mother was naive to say the least.)
I know of at least one other boy who had a sexual affair with a female teacher, in junior high school.
