This is sort of an odd thing to bring up, perhaps, but despite being an active user here for years I actually usually get off to erotica, not porn. Since 2020 I've also started writing smut, mostly on the GayKinkyStories (which used to be part of the Narccissus Mind Control website, or GaySpiralStories.
One of the things I like most about it is that writers can really go ham on a premise, since there's no set or CGI budget or anything. All sorts of crazy kinks that can't be satisfied in real life (or which are crazy unsafe IRL) but hot as hell when it's just fictional characters bouncing around.
Anyway, if anyone wants to read some smut but wants a better UX/UI than what nifty, AO3, and literotica have to offer, I highly recommend the GayKinkyStories.com site!
