Ah well, like I said I am a beginner myself and am still figuring things out! But I can tell you what little I have learned:
- If you want to generate torture scenes, you need to use a model that has been trained on such scenes! Most of the AI generators out there either barely understand what a vagina is, or have been trained only on mainstream porn and definitely have never seen anything like sexual torture.
- The best option right now (that I know of) is Pony Diffusion and its derivatives, a Stable Diffusion base model trained on basically the entirety of the boorus (sites like danbooru, etc.). These sites have a decade+ of carefully labelled hentai drawings of almost every possible kink, including many we like here. And since the tagging system on these sites is so good, it's easy to know what keywords to use in a prompt.
- Since the pony models were trained on drawings, to get more realistic results you need to use a derivative that has also been trained on real photos, and/or LORAs (mix-in mini models) that understand realistic nudity. This is the part I am still figuring out -- how to refine the raw pony-generated images into something closer to the style I want. Not quite there yet...
- Be prepared to spend an hour+ on each image in photoshop fixing glaring flaws...
