This model was trained on the following concepts:

• Crotch bulge

• Crotch bulge with exposed testicles

• Crotch bulge with shaft outline

59 training images @ 10,000 steps were used.

This is the first concept lora I've created and it is imperfect. The "crotch bulge" concept is by far the easiest to get usable results with. The "exposed testicles" and "shaft outline" concepts may require multiple generations to perfect. To speed up this process, once you have a bulge with the general shape you want, you can use variation seed + strength to hone in on a passable result.

No masculine/male characters were used in the training data, nor have I tested it on masculine/male characters, nor do I have any interest in doing so.

I found that SwarmUI's <segment> prompt syntax was helpful for cleaning up bulge image outputs and giving a more realistic/smoother result, but I suspect any Adetailer-like cleanup step would also help.

This model also works very well with inpainting/editing workflows

Additional keywords such as "big crotch bulge" or "round crotch bulge" can also be used to affect the image output. The model wasn't trained on these, but Klein seems to natively have some understanding of them.

If you want to help me perfect this concept by paying for runpod costs, feel free to leave a tip:
