A LoRA trained on a dataset of profession photos of Arad Winwin, and adult film character. Trained on danbooru tags and each image. Doesn't do close-up facial details very well most of the time, but gets the body features above the hip and his arm tattoo incredibly well.
Other recommended tags that tend to help (mix and match): solo, arm tattoo, short hair, black hair, facial hair, beard, undercut, bara, mature male, 1boy, nipples, pectorals, upper body, male focus, nude, briefs, underwear, navel, navel hair, shirtless
I recommend a homoerotic based model. I use a custom merge of homoerotic_v2 & Protogen Nova with bits of other models for generating mostly.
