What I've learnt is that all fetishes start off from something normal and just get progressively more extreme and degenerate if you don't have any other sexual outlets (basically a real relationship).
not a solid rule but something I just realized over time
For example, why are foot fetishes so common?
a normal guy who likes women notices things that make them sexy. sexy clothes and long legs etc, and by extension what do most sexy women wear? it's almost always heels. they become the 'indicator' of sexy... and bam before you know it, you've reached the end of that rabbit hole and you have a foot fetish.
Even extreme garbage tier fetishes likely start off mild. like someone who has masochistic traits wants to be dominated. They'll devolve into wanting to be degraded further and further, take that far enough and it'll devolve into literally want to get beaten, kicked in the balls, 'tortured' etc.
taking it further mixes in humiliation and the end of that rabbit hole leads to scat and piss fetishes where you get off on seeing someone be treated less than human, a literal receptor of waste.
Again, not a rule, just my theory with absolutely nothing to back it up at all lol
My guess is, from your list of preferences, your rabbit hole lead you down the path where you ended up enjoying rougher and more expressive sex to scratch your itch. NTR generally providing the extreme end of the spectrum with strong emotions, hyper expressive faces and it often climaxes with it getting as rough as the author is willing to go with gangbang, violence, degradation etc which is peak on the emotional scale.
If you can find something else that scratches that base itch, the thing that got you into it from the beginning, you'll be able to split your attention between genre's and you might not necessarily be 100% dependant on NTR anymore. although you'll still come back to it from time to time.
If you want another example - me - I love me some futanari porn
Teen me found it gross to see guys in porn. Obviously. So I went to lesbian porn. BUT I want to see girls getting fucked. Hard. So strap on was the logical next step. Then anime ruined young me and that was a good compromise because guys are just blank generic... until I found out futanari was a thing which was the best of everything. slowly became more addicted to that for a similar reason to you, its WAY more expressive and varied and generally leans into the same dom/sub archetypes that are similar to NTR. and then I read some doujins and that solidified my degeneracy in my teen years lol
so again, figure out what subcategories get your rocks off and find other main categories also encompass those little things.
once i figured out the base reason WHY I like futanari stuff, I wasn't reliant on it anymore. I basically just don't want to see any mans face lol
Probably wont solve your porn addiction in the slightest but it may help split your attention away from NTR
