Theres a lot of reasons. Most ppl I worked with who liked it had history with it. What was that shit princess bubblegum said in adventure time. "Some people get built different we dont need to understand it we just need to accept it"
Not everyone is a cookie cutter cut out of you specifically. Not everyone responds to their history as a perfect replica of how you do or how you think they should. Its not a control we are granted over each other unless we are given it by some one and that bares a lot of responsibility and they have the right to recind at any time
My partner and I do BDSM, and for me (the sub) it can be about control. The feeling of not being in control is scary to me. However, when we do a rape play, I give up full control to someone I trust completely. Even though I'm 'not in control' and being 'forced' to do something, I still am in control at the same time, because a safe word is put in place if I genuinely want to stop. The feeling of giving up control to someone I trust also has helped my control issues.
I also did ask my partner why they agreed to it when we first tried it (bc like Yuan, I, the sub, asked for it). They said satisfactory to them to put me in my place without genuinely forcing me to do anything. They can be a bit hesitant sometimes bc they don't want to actually hurt me, but they know I'm enjoying it.
I kinda rambled but I hope this makes sense
1. Someone has a kink for being so desired by someone that that someone will throw away social morality to have them
2. Someone has a kink for being held down and treated roughly
3. Someone has trauma related to rape in their past and CNC helps them process it in a healthy way
4. Someone comes from a sexually repressive culture and is told desiring sex is wrong and dirty, so in order to explore their sexual desires in fiction without the feelings of guilt related to desiring or wanting sex, it has to be at least initially be non-consensual in the story until the character makes the transition into being openly able to admit their sexual desires.
5. It’s complicated.
Same its not my cup op tea at all either, I do think it has to stem from something bc why else find so much pleasure in raping someone? I once read somewhere that it’s a thing for people that grew up with the virginity is sacred mindset. Bc alot of these ppl grew up learning sex is something bad and you need to stay away from, even when once they are ‘allowed’ to do it after marriage the sense that its taboo still is there so rape-play feels safer for them (bc its done against there will obviously). Idk just thought that made sense.

I love roleplay for a little spice but I genuinely don't understand r*pe play. Like what's the point of it?? You got turned on when the other person begging not to get r*pe or what??
