I wear clothes that definitely show what I have sometimes, both visually through the mesh or just the outline, but I literally never walk around in public with an erection - ever. When I am wearing shorts or pants that show what I have, I am flaccid. Sure, I'm older now, but I never did when I was younger either. Let my wife grab me in public (highly doubtful) and I'd probably get erect, but that would be different than me simply walking around with one. As for me ever seeing another dude walking around with one, he'd have to be hung like a horse for me to see it because I just don't look at guys crotches.
