i feel like this is super late stage coomer stuff. my theory is a lot of guys like a little bit of dominance and submission (not talking BDSM mind you, just in general. that's normal and healthy in the context of a good loving relationship) but when you turn that into a fetish and watch so much of it you fall into the desensitizing spiral so you have to watch more domineering stuff.
Eventually you reach a point where you're not even really getting off to the sex, your getting off to the idea of having power over another person and being able to do whatever you want to them.
It's a Porn sickness the same way watching tranny porn often leads to people chopping their dicks off. degenerate stuff.
growing up i had a youth pastor who use to say porn made people violent, which to be fair to the coomers i suppose isn't largely the case (there's a lot more common negative effects then that) but stuff like this certainly helps him make that case.
