Question about NTR

I've started playing AVN some months ago and i have played a decent amount to this point and the more i play the more i don't understand the NTR genre (i'm not trying to criticize anyone just my personal opinion ).
Maybe because i like the oposite end of genres, i like harem with male domination scenarios, or even non harem game with multiple LI but with the main character being in control and form a connection with the LI.
But there are A LOT of games with NTR or sharing or with a FMC and all the game is about corruption and make the girl get fucked by every man in the game or even raped.
and i don't understand the why would someone like that.
I've tried some games like that to see if i could understand but i hated every second in those games.
I played "The adventurous couple"(This is sharing/cuckholding), "Life in the middle east"really hated this one (this has a FMC and is about cuckholdig your husband or strait cheating or even getting rapped), "Max's life" (this is a sandbox harem but has NTR you have the option to turn of NTR but it's obvious that the game was make with the intention to have the NTR on because if it's off some scenes don't make sense )
I tried and ended up with more questions.
Why would someone like to see the woman they like getting fucked by multiple men? what is the thing you like in that? what make you feel? Why is that you like it so much?
I'm not trying to insult or criticize nobody , i just really want to understand why there is so many people that like NTR .
