Awful, and now everywhere. A young boy kissing a girl (11 or 12) started to choke her as he had already watched enough porn to learn that females love to be choked and punched and torn apart etc. This problem is so vast that the solution is unlikely to be easy, especially as vast numbers of men (and some women) defend their right to porn to the last breath.
I have read that someone addicted to porn needs stronger and stronger doses, just as addicts do for some other types of drugs, and that those stronger doses are increasing amounts of misogyny, rape, abuse and humiliation of women.
And something like a third of boys now get their sex education from porn, I read recently. Schools, at least, could mount a counter-campaign about what loving sex is.
