This is my first LoRA which was made because I felt there was a lack of representation for people who are into attractive men. You might not get a photorealistic look with this, but you are welcome to try.
I'm sure you could get some NSFW pics if you really tried to.
Applying around 0.6 - 0.3 seems to give the best images.
His scar was really hard to get working but, with a bit of persistence, you can get some good results. I think the scar was mistaken for hair during the training, so it renders as hair sometimes. The gunblade is pretty much a no-go. It's in this LoRA, but it never really renders properly.
I haven't had much time to play with this, but I'd love to see what you create with it!
