Looks fine to me, I'm 70 soon and my penis is a fraction of what it was, floppy as well but it still gives me pleasure. These days I need to use my tongue to please other people and in some ways it's better, it's certainly more intimate
As you are you look fine, you have a great hairybarse and a lovely cock.
I'd sure enjoy trying to suck some of your huge thick cock.With some jacking and sucking I'll bet I'll be able to coax a load of cum from it and of course swallow it all.
