DeviantArt (a lot of low-quality shit but it has the occasional good piece of art and artist e.g. shoxxe)
Fur Affinity (If you don't like furries, forget it but if you do it's pretty good)
People like PersonaNonGrata do stuff on Patreon but I've never become a patron before so I can't say much
I don't have a twitter account but when I lurk on the site the fetish stuff I see is almost always something you can find on other sites (e.g. Pixiv)
On YouTube there's antique scuba and this pretty small Japanese vtuber news channel which I will link to
