This is a powerlevel, but when I was younger I was interested in BDSM, and I can tell you, 99% of the doms were sexual sadists. The whole consent shit? They were just covering their asses because they knew what they wanted to do with their subs teetered from borderline abuse to outright violence. Some of the men I encountered were not even this considerate, and made no secret of the fact they wanted to send me to the hospital and even said they'd pay for the ER visit, and the only consent they needed was the fact I would consider seeing them. And, I had my own issues too, which is why I was even interested in this shit and contemplating it. But after literally every dom I encountered was all "I want you to hurt, I want you to bleed, and fuck safe words, I'll be the one who decides when you've had enough you fucking whore", I quickly noped out of this shit.
I'm actually still friends with one of these guys, and he was definitely more sane and not as sadisitic, and we shit talk about trannies together among other things. We still talk, and he even comments that if we had actually pursued this shit, he would have probably traumatized me and would have gone far beyond what I would ever be comfortable with. Jesus, he had to even protect me from one of his friends, who holy fuck, even attempted to try to come to the city I was living in, to literally rape me and make me bleed from every orifice, that's how much of a fucking sadist he was. I'm honestly surprised this guy isn't a serial killer, that is how fucking deranged he is.
BDSM is not what 50 Shades of Grey tried to project. These men are sadists, they want to fuck up their subs, they want to visually see the abuse they inflict on them, and they are very well aware that their fantasies will warrant a trip to the hospital, where the sub will lie about what happened to them, or otherwise state "DON'T JUDGE MY KINKS!"
It's really sad and horrific for the people who are into this, because it is literally abuse, but shrouded in the whole gaslighting "Pain is how I show you I love you" shit. No. These fuckers don't love you or have any loving feelings for you. They want to inflict pain and get off on abusing people, and they see don't see you as a person, but just something they can abuse and get away with.
