Yes. It is very possible for average dudes to look incredible naked, even to traditional beauty standards. Plenty of gay photographers take on this challenge and have portfolios filled with such shots (presumably in part for the challenge and in part for the subject matter).

Technically this is a tangent to the question you asked, save for the case where they do nude self-portraits. Nonetheless, I have been to a few homes where all the walls filled with their own photos of basically average gay bears in posing in very artistic ways that I’d assume were professional models, if not for the fact that I could identify subjects to their local ‘online dating’ profiles. (And to be clear, while some photos definitely have ‘I’m here to fuck’ energy, many more were going for tender vibes and artistic poses).

Guys with [good, interesting] tattoos appear to make great photography subjects - I suspect that it gives the artist something to compose the rest of the shot around. Unless you’re a modern prude, tattoos don’t carry the stigma they used to, they’re [often] artistic, and broadly well-fitted to the male beauty aesthetic.

Wish I could give you names and such, but in my defense I generally wasn’t visiting to see the wall art.
