I hope she receives counseling. She may not realize that even with testosterone running high, most 17 year old boys do not force themselves upon 15 year old girls.
It may have been that way for her or her friends, so for her this may be perfectly normal.
But it’s not. It never was normal.
I should find it but there is a Facebook post going around written by a man that says:
“Men, read the comments and pay attention to what you see”
and it asks something like:
“At what age did you first notice adult men looking at you sexually?”
I looked at a number of the comments. Sadly, I was not shocked at the ages and situations I saw there. I should be shocked but I already was aware that while most adult men aren’t like that, those that are are “serial” and will find their way to many many to make their presence known, whether by leering inappropriately to things much much worse
