My second time trying to make this kind of LoRA, it's just a try, didn't use too many pictures when training. It mainly affects erect penis(not sure if working well with flaccid penis with foreskin). Like the previous one, this LoRA still has a noticeable side effect: sometimes it alters the skin texture in a strange way(even though the lora in a low weight). You can try to counteract this by running the output through img2img. (So far, I only found that oil painting style can decrease this side effect
