A considerable amount of time has passed since I last voiced my opinions about erotic fan-art produced using AI tools. In that time, while looking over sites for erotic fan-art which appeals to me, I have necessarily been subjected to viewing a lot of such art produced with such AI tools. So, do I have anything more to add to what I've said previously?
Firstly, I still hold by the opinions which I have expressed before. The bulk of AI-generated erotic fan-art is boring and generally worthless for stimulating one's libido, or at least for stimulating my libido. Nonetheless, someone who is sufficiently imaginative is capable of using AI tools to produce erotic fan-art which is interesting, exciting, stimulating, or to which other positive adjectives may be applied. Such sadly doesn't happen often, but it does happen occasionally.
However, one new comment which I would like to add is that most such art suffers from the fact that the central female character is rendered sufficiently well, or even very well, but the male characters included in the image are virtually always generic rather than being taken from the male characters of the universe in question. This is something which is considerably more rare in art created by a human.
If I see a cartoon in which Akane Tendo and some guy are getting it on, then I like it when the guy is Ranma, or Ryoga, or Kuno (father or son), or Happosai, or her own father Soun, etc. I don't mind the occasional cartoon where Akane is sucking the cock of some random student at Furinkan High School, or getting gang banged by some unknown group of men who have abducted her. But I like it when the bulk of cartoons I am looking over featuring Akane (when she is not solo) also feature boys/men from the Ranma 1/2 universe.
