"It's a well-known fact that cooming too much makes men search for more exciting and even weird porn."
No. That's as stupid as it is misspelled.
I have made 16 submarine patrols, and was in charge of tge porn locker for about 9 of them. So i have only anecdotal info, but what i have says you're ignorant.
If, let's ay, "Playboy" satisfies a man, he'll continue to use Playboy.
If it fails to satisfy, then he'll look into Penthouse, Hustler, then more "specialized" stuff. The various fetishes and situations. Until something works.
It's when you CANNOT come that you trade up.
Now, if you're not THAT horny, but beating off because you're bored, your dick becomes too abused to respond. Then you drive yourself to harder porn, thinking it's the smut tgat's failed you. Try taking a break from the beating. Turn to some other interests....
Oh, wait, you're incel. In your case, go straight to the amputee dwarf fetish. Shetland pony centaur porn.
"what would happen if women were forced to watch incel porn for multiple hours on a daily basis while they get their pussies stimulated at the same time?"
Forced? It's rape, then. I mean, if she lets you stimulate her pussy, you don't need porn. If you're forcing the situation, that's rape. This is YOUR porn.
What would happen? I guess, chafing.
"Would they develop an incel fetish and finally not feel much arousal anymore when Chad is around?"
No.
"Or wouldn't it be of much help?"
Help? You're asking if raping a woman would make her want to fuck you instead of the mythical Chad? You seriously need to ask?
