Terrible to hear and it sounds like a mean violent rape here. About the consent education, that's a problem but also some people certainly find their pleasure in assault and "stealing" someone else, and even violence. You're not going to educate those ones. This is basically evil sex.
The show "I may destroy you" talks about different kind of rape, when this can be more ambiguous let's say. I'm sure tones of shit happens between guys with problem regarding consent at different levels. That's on education then probably.
As a top i learned to be careful about that cause in horny situations there is some sort of natural role play involved and you're meant to show some determination at some point. The other guy expect that, BUT you always always want to be sure your determination doesn't pressure him into doing it. That's why i don't like to plein ask for it, cause, even if it's not going to be seen as rape, you can really easily have a guy being like "ho ok let's go haha" cause he doesn't want to break the flow or he wants to please you. He may also not like it at all after that and being like "haha sure no prob go on haha" so really it's always about being super careful about that and asking sometimes many times and all that. I find the best is still to wait for the bottom to initiate.
Anyway i hope it's not tone depth to talk about those issues there. Cause OP's incident is not about consent culture i think it's plein evil barbaric shit.
