When I was 14, I was really horny. I loved exposing my cock to the fresh air, daring people to see it. I went through a phase where I would let my dick hang out in restrooms. Whenever I walked into a public bathroom, I'd whip my dick out, way before I reached the urinal. Then I'd only stand as close as I needed to at the urinal so that others could see my dick. Once I was done, I'd spin around still with my dick out and only put it away right before I left the bathroom. If the bathroom was empty, I'd sometimes watch myself jack off in the mirror before leaving.
I think I ended up flashing dozens of people.
