Ok, continuing.
I think what JP is saying about casual sex actually isn't too far from the idea of toxic masculinity; that is, he thinks society has trained people to have defective and destructive views about sex, and they aren't quite aware of how destructive those views are, yet they still condition people's behaviours. In a society where sex is something that is seen as a trifle, and something that can be gotten (or should be gotten easily), where it's something that can be desired like a consumer gratification, people will pursue it as if it were a commodity, as if it didn't require intimacy and the greater context of a close relationship. If you divest sex from its association with relationships, then it becomes a matter of individual gratification, and that mindset drives individuals to coerce others to satisfy their personal desires at the expense of others.
