(NSFW) Is this business of female teachers having sex with male students a new phenomenon, or did I miss something in high school?

It seems like once a week, I see one more story about a female teacher screwing a male student. And while I might understand it more when the teacher is unattractive and maybe lonely, some of these women are pretty cute.

I remember there was always a rumor about one of the teachers at my high school, but I think it was just talk. Truth is, I am totally unaware of any of this type of thing going on when I was in HS.

So either I was just distracted by sports or girls my own age, and thus unaware of it, or this is sort of a new social development.

And if it is sort of a new thing, what is going on with these women? I am sure the adolescent guys might be intrigued at that age. Plus, I am sort of accustomed to hearing about grown up men falling for younger women-that’s what Lolita was all about, right?
But what is going on with these women?
