These events are just as much about alcohol, misplaced trust in strangers, personally unsafe arrangements (sharing an AirBnb with an unfamiliar person), grossly disproportionate social influence etc. etc. as they are about "sex". In fact, even the sex the OP talks about was clearly coerced.
We should stop treating "tell folks not to have 'unacceptable' sex" as if it's a foolproof solution to all social problems. It just isn't.
