I've seen no direct reports. I have seen indirect evidence, such as a late-teen asking "what these flaps on my vagina are."
As far as I can tell, it mostly involves p2p discourse and webcamming on the internet. Which is probably moderately educational. As far as a magic world in which children are treated as people, or even where unwanted contact is discouraged (remember - "sex ed" used to mean stern lectures not to talk to strangers about what goes on at home)... I would hold out little to no hope.
I... hope you can wrap your mind around this text. If not, keep your questions specific, because vagueness gets chucked. I'll explain words to children, not give credit to formless harassment.
