Inspired by the excellent WAN LORA Uncutwang I trained a set of 40 naturism style images of caucasian men with flaccid uncut hairy penis. As the training images were from the neck down you do need to reinforce that you want the face to be visible or even better use a character LORA. I think it performs fairly well, given that the penis is always notoriously hard to generate.
I tend to mix it with Uncutwang keeping that one at 1.0 and mine at 0.6 to get the shape, pubic hair while maintaining the original model's better flexibility.
Versions:
