As you say, there's porn for every taste. It's a social phenomenon that needs to be studied carefully, and from what you say, perhaps that's happening.
I object to some of what is offered, for the same reasons I object to some of the particularly violent video games, because it normalizes antisocial acts and even offers a chance to rehearse them mentally.
My main complaint about a lot of the rest of it is that it's just plain silly. But I also agree that the industry miseducates a lot of men by leading them to think women like activities that most find physically unpleasant.
