I was the subject of such rumors when I was in my teens, several times.
The rumors were always started by another girl who was jealous in some way. Of course they were never true.
They caused me the most trouble with my paranoid alcoholic mother who insisted that “Where there’s smoke there’s fire.”
I was a virgin when I married in 1964. You could not pay me to go back to those years.
There wasn’t much of this when I was a kid. At least I think there wasn’t. I was not involved in such. I am really, really glad of that disinvolvment, too. I am still remote and uninvolved...nothing has convinced me to be otherwise once I became an adult. It seems to lead to nothing but sadness and dismay and very disengaged people.
Who was supervising the so-called boy and establishing his morals, etc? I bet no one except his peer group.
