Okay, you younger guys. Is this really true? It's been 20 years since I retired and no longer had access to my employer's gym, but at that time no one worried about showering naked in the presence of other men.
Of course, back then the queers were "in the closet." We didn't even know who they were, let alone worry about it.
I shower in the presence of open gays in my work. It’s not a problem. They’re not into me. I don’t spend any more time with my business exposed than necessary, but I don’t go so far as to dress under a towel. I have NEVER seen any of them do or say anything to make anybody else uncomfortable.
You know who the worst shy babies are? Muslims.
