I'm so sorry that this has happened to your daughter & your family.
I so so understand your rage.
It's so cheering to hear she has a loving family around her who will support her, so many rape survivors just don't.
This lad... Has he been prosecuted? .... Raping a child as a child is a good start to an adult sex offender career...
The state is failing him and society without targeted therapy.
Think you're right... These young men have been badly let down... Violent porn ending up in the vaccum... With the absence of decent men in their lives to show them through words and actions, how to respect other people....
And also, more importantly... Everyone has (some sort of) sex drive.... At 15, hormones are flooding your system...and brain development isn't adult yet...
It's much much better to have solo sex than EVER expect someone else to be forced by you into sex activity.(as well as being illegal.)
Sadly, violent porn teaches young male brains that girls /women 'enjoy' forced, violent choking /rape.
I wish your daughter healing.
