I understand that you are very frustrated but I do not think that public solicitation for photos of genitals is appropriate.

At the end, it does not matter how somebody else's changes look like , it is about changes that you have and due to them have real issues. Maybe the urologist is not a right person to talk about self- image issues since he is not trained to deal with that nor knows how to help you. I am saying this in completely well-meaning way. In what way looking at somebody's else changes can make you feel better or worse ? If somebody else's changes make you feel better you have a very real and different problem that needs to be addressed.
