When I was 18 or 19, and that was legal drinking age in Texas, one of my leisure activities was getting some beer and going over to the Lone Star Drive-In which was an X-rated theater.  I would usually get high in the car, and sit through all the movies usually jacking off in the car.

One night while I was there I had to go to the bathroom and I went in and there was a guy standing at he urinal and I went up and stood at the one next to him without giving it a thought.  My cock was already hard as a rock and I unzipped and pulled it out with it standing almost straight up.  I had a real hard time peeing with an erection and I was standing there waiting while I noticed movement to my right.  It was really then that I looked at the guy.  I would remember him if I saw him again today, 35 years later.  He had dark hair and moustache and wire rimmed glasses, and the movement down below drew my attention.   I had kind of forgotten about needing to pee.  The movement drew my eyes downward and there he was staring at my cock with his own cock rigid and being jacked off.  I held the look a little long because it was really an awkward feeling.  Never had I felt so attracted to something and yet repelled at the same time.  I looked away and then decided to look back.  I could see he was pumping more feverishly and getting ready to cum.  At that point I stared down with amazement as he shot load after load of hot cum onto the back of the urinal.  He didn’t touch me.  He cleaned up and left.  I eventually pissed and then went back to my car.  I could not concentrate thinking about what happened.  And then I suddenly began feeling myself getting aroused and turned on by what I had seen.  I decided I wanted him to see me jack off.  I went back to the bathroom and kept standing at the urinal waiting for him to come back.  I was turned on by the idea of somebody else seeing me cum.  Why do we feel that way?  Surely it’s not just me. 

Anyway, this was the beginning of a number of similar type encounters that I learned to find and seek out…but that’s another story.
