Funny I read this thread today. I actually posed this morning.
The guy contacted me on a website where I posted some pics of my body and dick, and he proposed to try to take some shots, see if it could lead to something.
Very professional, though he did very briefly touch my dick and ass during the proceedings.
We had made clothed, partially clothed, artistic nude (no dick showing) and full nude. At the end he also took pics of my hard dick.
That was nice, wonder how this come out

If it looks good, he can do a book...
