I was at my gym a couple weeks ago. I generally never use the locker room and I always forget which one is the men's and which is the women's.
I walked into the locker room and saw an asian guy sitting there with no shirt on. So I immediately go to the other locker room.
I use the bathroom and when I walk out, a naked guy is standing there. I run out of the locker room head down and leave and don't go back to the gym for 2 weeks. The next time I go back to the gym, I get on the treadmill and the guy next to me is the naked guy from the locker room. He looks at me, shakes his head and walks off in disgust.
I guess the topless asian man was a woman.
