While the videos are controversial they are accurate in showing why these practices are a bad idea.
But as for the rape, as someone's who done a good deal of sex/gender research i can say that rape is almost never about the actual act of sex like actual sex is. It's about the power, control and pain they are causing someone else. That's what they're getting off on. So I don't think that, for the ones who are still intact, are thinking of that type of pain for them. They are getting off on knowing the other person is "beaten" by them. Granted though it sounds like having the skin gone may make rape less painful for the rapist in that sense...
But I never knew that, for a man who is still intact, not being fully aroused could be painful if they try to have sex...
Appreciate your response and research @lydiaravenswood, I agree it's not easy to perceive where a rapist mentality comes from or even how it originates. Seeing it from your example, these males are not caring about anyone else's pain. Especially when getting off on power, dominance and beating/abusing the victim.
To me this still represents the imbalance of the internal masculine/feminine energies. Post traumatic stress from any early physical, mental or spiritual childhood injuries are of course not defenses. Perhaps just another example of societal cult-ure practices are often overlooked.
Of course it would be difficult for anyone without a intact penis to identify any of this as possible sources of equally harmful actions, intentions or manifestations.
Above all I get and respect your point.
Um, I'm going by the scientific route as we do seem to know why a person, not even a man, rapes. The chemicals in the brain are already messed up in how they think and consider others lives and how they affect them. So rape, for them, mentally from birth, isn't a "bad" thing in the way the rest of us see it.
There is some debate on the nurture aspect. Again, this is from the angle of all genders. Cause females do rape as well. They were abused at some point in their life, usually sexually, and perpetuate that violence because the brain was damaged in the process of the act.
