Not sure what you're getting at exactly - are you suggesting that men who watch it really want to do it, but just think otherwise due to societal indoctrination?
Not quite. And this is where the civilizing factor comes in.
Male biology is designed to allow them to compete for mates (in fact drives them to it) and to procreate with them. Nature created sex for procreation and nothing else, it took humans to turn it into an Olympic sport and throw in guilt.
The concept of women having "rights" even not being some sort of property (one of the reasons Elizabeth the 1st never married is her society required her to 'obey' her husband and she felt a Queen of England that conflicted with her rights as Queen) is a fairly modern concept. It is only recently that sex with your wife against her will has been considered rape.
Most of what we see here has a sexual aspect to it (display of the female body or sex acts) which appeals to the base human drive to procreate. There is also a significant domination factor by the tormentor (usually male) in what is portrayed here. In older societies with little or no restrictions on males seizing what they wanted, by force if necessary, it was not only common place but accepted this physical dominance and sexual rights.
Modern society teaches a form of relationship between men and women which is not biological but is based on rule of law and 'respect' (and trying to turn females into ersatz males).
The teachings of civilization clash with biological drive (which is far older and ingrained into our DNA), so biology drives the male towards wanting to have sex, to be dominant (even if violence is necessary) but our teachings tell men that is not acceptable.
Result subconscious confusion and guilt.
All societal transitions are really nothing more than a transfer of power from one group to another. The group with power resists the transition, the one without demands it. Usually it works out pretty well unless we try to fight nature itself, in this case hardwired biological programming.
Most men today accept that what is portrayed here is unacceptable behavior and will not engage with it but they would never be watching (pr creating) it if there wasn't a certain appeal to aspects of it.
And I don't disagree with the concept to rule of law. Personally while I may have rape fantasies I really don't think it is in my best personal interest to be seized, raped by a man )or men), dragged off to his castle and be barefoot and pregnant in the kitchen until the next pretty thing catches his wandering eye.
But I do recognize the clash of the immovable object with the (currently) irresistible force.
