I think that in undressing amongst men, social dysphoria is added to body dysphoria, making it a big goo of pain

. I never really felt that pain since I never did it and never showered with in a public shower except with a bathing suit on (at a pool or beach).
Most time, I had to wash as best I could with towelettes in the bathroom stall (again). I smelled nice at least ;-).
I never in my whole life undressed in the locker room, went to the locker room's restroom; I didn't quite understand why, I wondered if I was a prude? But, in general I was not, so I didn't get it.
I had one of the best body of any guys in all my high school, I was one of the two top athletes, yet never showed it off to anyone, It was for my track and fields performance and not for use in proving my so called manlyness...
