Since coming to lemmy I will browse all vs local and top by day. There is a solid amount of AI generated porn that has many votes in a 24 hour period.
To me the whole vibe is plastic tits and “smooth” skin. It looks off even when done well and all the faces look the same. Is anything it’s more a technical feat than what helps me beat my meat. Also it’s nearly all white women or pale Asians.
Between the removal of nsfw from r/all and my browsing Lemmy there seems to have been quite the explosion in AI generated nudity. One of the things I liked about the r/all nsfw was the “discovery” as I might flip through the days latest news. I say that because the images I’ve seen are whatever you horny bastards upvote enough to make a Top list. The AI images look like bad Instagram filters - or maybe filters that are just too good. It’s almost past the uncanny valley, but not quite. As for the skin tone and ethnicity I just assume that’s the bulk of the user base self-selecting.
I will say that my teenage self would have been salivating at these. The older me finds most of them, if not disturbing/offputting for appearing so young, a bit too perfect for my taste. To drop a quote: “the sadder but wiser girl’s the girl for me” these days.
