I shower at my local YMCA almost daily after the gym and I’ve noticed a trend. My Y has stalls and curtains (which I don’t close). I have found that some straight married men will close the curtain and jerk off in the stall. You can easily tell because there is a light overhead each stall and the shadow clearly shows what they’re doing. They also seem to be doing this completely by them selves and not being creepy. I think this might be the only place they have since maybe they have kids and or a wife who doesn’t give them any attention at home. I’ve seen this fairly often that I wanted to see if others have observed this as well?
