Why is it?
If your muscles are wasting away - you should be able to prove it with pictures. Penis enlargements forums (exercises specifically) post pictures of there penises. It’s not a big deal and I think it’s very appropriate, because people can make whatever claims they like on this forum but if you can’t back it up then hardly anyone will believe you.
It should definitely be given a thought, maybe exclude pictures of genitals because I think a lot of the non believers may mock it over on the hair loss forums.
