First (and only) experience at a highway restroom

I'm a bi-curious male, with no experience with men except for this story I'm about to tell. I was coming home late at night (2 a.m.) and I stopped at a highway restroom to take a piss. When I entered, there was only one guy in there and I took my place two urinals over and took out my cock wich, because I was dying for a piss, was semi hard and started to piss. When I finished, I felt observed and looked to my side to see that the guy was not only watching me but he was holding his rock hard cock in his hand and stroking it. At that moment I felt my body freeze up, not knowing what to do. I never been in a situation like that and felt a mix of fear and excitment as i watched him jerk that big cock. Without even taking notice i found myself shaking my cock way more than the necessary times and it started to get hard too. Before I knew it my cock was fully hard and I was jerking it hard, the fear replaced with pure adrenaline and excitment. The guy noticed the change in my attitude and signaled me to come to the urinal next to him and so I did. For a few moments we stood side by side watching each other jerk his meat. I felt so hot looking at that big cock beeing stroked that I made a move that, to this day, I can't believe i did it, and with my free hand grabed his cock and started jerking him and me at the same time. I felt his excitment, as his cock pulsed hard in my hand, and he let me jerking a bit before doing the same to me. Now we were jerking each others cock and it felt awsome. I was jerking a total strangers cock in a public restroom! What was I thinking?! Probably that same thought passed through my mind at that point because i let go of it, pulled my cock away into my pants and left. The guy still signaled me for something but I can't tell what it was since I didn't even look at him. When I was gettin ginto my car, someone was entering the restroom. What if I hadn't let go? Would I have been caught? I always wondered that... Nevertheless, the thought of it stayed with me until I got home and I had to jerk it off and cum like crazy to calm myself. It was a rush of an experience and hasn't happened to me since, despite now I'm more aware of cocks around me at public restrooms. Hope you enjoyed me sharing my experience. If anyone is into this please let me know. I would love to talk to someone who had experiences such as this.
