Looking closely in the interests of research
I think he's on the way down from an erection and it's just going floppy without getting much smaller. The skin where his foreskin used to be is very stretched. His scrotum does look a bit odd, but when he's harder, it is probably nearer his body.
I am surprised any escort would make rude comments about his looks. I'd do him. He's a lot nicer looking than some.
I will have to take a photo the next time I
come down like this for comparison
