I went to UMass, Amherst, and knew a few gay bars. I discovered if you sat in the toilet stall and looked to the right, there were small eye holes that were perfectly placed so one could see up close, inches away, guy’s cocks as they pissed into the urinal. It was erotic, and the smell of piss and the dirtiness of it turned me on, and I would jerk off as I stared at cock after cock being un-zipped and pulled out.
