Conclusion
First, congratulations to all the creators of these amazing LoRAs!
These LoRAs excel at generating images of nude women, which appears to be the primary intent for most of them. However, the male body proves more challenging, often resulting in anatomical inaccuracies—such as men with female genitalia. Depicting sexual acts is even more difficult, typically requiring specialized LoRAs for different positions.
While no perfect NSFW LoRa exists yet, MysticXXX v3 demonstrates promising results, even with standard CLIP and T5 settings. I’m aware of custom-tuned versions of these models but haven’t had success with them yet.
Admittedly, this comparison has limitations—testing only one resolution and seed provides a small sample, and varying prompts would yield different outcomes.
Feel free to share your own results, and thank you again to all the LoRa creators! In the future, I may explore compatibility with other LoRAs and styles (e.g., anime, pencil drawings, comic books, etc.).
ps: I attached a new version of the workflow without groups, some people had problems with the first one.
