[Josh Collection] - Gynecomastia & Puffier Male Nipples (Flux.1 Dev)

This model is great for people who like their men to have a little bit higher of an estrogen level affecting their chest. This gives the men you generate a more "average" looking chest that is more representative of the general population.

It has been tested primarily with the euler sampler with a simple or beta scheduler

Works well with flux.1 Dev ultra real fine tune and flux.1 dev regular

LoRA strength works best between 0.65 - 1.0. The "intensity" of the effect is proportionate to the strength of the LoRA. I didn't test with values over 1.0.

I used between 25 - 40 steps

This works with other LoRAs that work well with a similar sampler and scheduler, HOWEVER if the other LoRA alters the subject's chest, this can cause the LoRA to conflict poorly.

I've tested with many image sizes and haven't seen any issues.

Additional Notes:

Sometimes the man's face/hair might appear feminine. It usually has to do with the prompt you give it, as none of the training data contained females. If the face/hair appears too feminine, try adding "feminine face, feminine hair, ugly face" to your negative prompt or adjust your positive prompt to include more masculine face/hair features.

I didn't have much quality training data on subjects of non-European/Asian descent. In the next version I'll fix this. Nipple piercings also work unpredictably.

This works on all-sized men. The more husky the man, the more the nipples will just be large and appear like "moobs". For leaner men, they will appear more puffy and conical. The effect works well on bodybuilders/muscular men too.

"man-with-gyno" is the trigger phrase that should be added.

Unfortunately multiple subjects tend to "all get gynecomastia". I will try to improve on this if I create a Qwen Image version. You can try specifying weights in your prompt to discourage this from happening.
