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.

I'm still a noob of making lora, feel frustrating when failed to make perfect training data, but lucky I got some buzz recently, at least I have plenty of time and chance to try.

There will be a improved version but won't be soon. (If someone can do that for me, I would be very grateful, but the reason why I make this lora is because no one do that).
