@AltAfterDark Some of my stuff might be relevant. I'll link to my index posts.
I have kink-oriented erotica here, which I'm slowly recording audio editions of:

I also make and post faithfully alt-text'd porn:

I should note that, because the sexual stuff is part of a larger artistic project, some of my work is designed to ask uncomfortable questions about consent, boundaries, gender dysphoria, and identity, rather than be overtly arousing. I clearly content warn and title the stuff that's about trauma, but not everything's light-hearted in there.
I share a server with someone considerably more adorable, who says I can mention their work, too. @sacralizedacolyte posts about transmasc and genderfluid sex & sexuality, creates tender and artistic nudes, occasional audio erotica, and posts poetically about kink.
Their CW game is amazing and he alt texts every image and audio file she posts. They have an art & illustration account, which includes erotic illustration, recently migrated to @supernovacircus
