I'm sure the answer to this is just like several other answers. At some point I'm sure a large percentage of guys have jerked off in a shower. Maybe at a gym, maybe at home, in a hotel, as an overnight guest with friends or relatives. Who cares? What's hot is if they are doing it for others to see or in hopes of getting caught! I sure enjoy watching as much as jacking for show. I have definitely jerked off in locker rooms and gym showers. Steam rooms and dry saunas too! I love it and have no intent to stop any time soon! If you see me doing it, I'm hoping to hook up for even more fun.
