I came of age in the late 40's early 50's. The following are true memories of my fascination with the "restroom" from an early age.
The first indication that I was "different" occurred in the first grade. I went to a four room schoolhouse just one street over, After the first couple of days I was allowed to walk over by myself. The first time I raised my hand to go to the bathroom the teacher asked an older boy to accompany. We went down the old wide wooden creaking stairs to the boys room. There was this long, 4 or 5 feet high, black slate wall with a long water pipe leaking cold water to the slate trough below on the floor. That was our urinal. The other boy also had to pee. I couldn't help but look at his penis. I got excited. After that I always tried to go when I knew another boy would be there, I even looked out of the classroom door to see if a boy from one of the other classes had gone by to go to the restroom
My next memorable encounter occurred when I was in the next level of elementary when we now had gym and had to shower I was around 11. We shower in pairs and one time the boy that I showered with was almost through puberty and that was the first time I saw some hair around his "prick". That is what we now called it. Being very scared of what I was feeling and keeping it a secret, I went home and rubbed one out in my bed with my pillow under my hard on. heavenly!
After that It was in Junior High. At the urinal, just through the double doors to the gym lockers there was a friend, Richard. I also had to pee. There were no modesty panels. I looked down to watch my pee and looked to my left to see that Richard had a hard on. His was not as long as mine but still impressive. I looked up and he was staring into my eyes. Neither of us said anything. That night and many other I jerked off to Richards' boner.
When in high school, I would have to walk to the downtown area and on the way there were three underground public bathroom. There were more in the city that I later encountered. I would stop at one particular one and see that there were often times a few men and boys that would linger at the urinals. When a new person would come in they would all press against the urinal hiding their goods. I decide to "linger" also and discovered the wonderful site of several pricks sticking straight out. Many, many nights of pleasure at home. One day I was about to leave the bathroom and went to the sink to wash my hands. I the urinals were on a one foot high platform. The sinks were right at the end of the bank of 16 or so urinals. At the first urinal right next to the sink with his cock right about my eke level was this beautiful black boy. One of the first black boys that I had even seen. He too had a hard on. His cock was so exciting, uncut, with his foreskin wrapped around the head. I was so close and I desperately wanted to take it in my hand, but I was closeted and so scared, I was shaking. I left and he now became my dream at night.
Perhaps my most fantastic encounter occurred just after high school and after basic training. Basic training was torturous in itself, but that is another story. One day after completing my work for the Air Reserves, I went into Manchester NH and to a theater. I was so horny, I didn't pay any attention to the movie, I just searched the seats for any hot looking guy. I went to the rest room and there was the traditional long bank of urinals without the modesty panels. Out of the corner f my eye I saw a body at the far right so because I didn't want my erect cock to be seen I went to the far left. Then it happened... a rustle of a bag and I looked to the right and there was this young adonis looking at me. He was blond, with white shorts and a red polo shirt. He pulled back to show me his hard on. I again began to shake form the pure thrill of it. He was so beautiful and with a 7 to 8' man size cock. he motioned for me to come next to him and I did. When I got next to him I really saw just how handsome he was and how nice his cock was. he reached over grabbed my prick and told me how much he liked it. I am uncut he was cut, my cock was slightly bigger than his. It felt so thrilling to have his hand around me and he was jerking me off. Then it happened, eh asked me if he could suck me and I said yes but where can we go and he just dropped to his knee and took my throbbing cock in his mouth. He gave me my first blow job right there in the exposed room, me trembling but oh so excited. if anyone had come in would have died, but not before I shot my cum into his waiting mouth. I want to at least jerk him off but as soon as he finished me he turned to the urinal and shot his load. Walked out of the theater together and I learned that he was just 17, I was 19. He was an only child and lived with his parents. I never saw him again but he was the inspiration for many jerk off sessions for many years.
Later on when I got a job that was in the center of the city, I was again at the underground bathrooms. There was this young man that would travel from one underground bank of urinals to another. he caught me doing the same and one day invited my to a stall where he sucked me off. He was in his late teens and me in my mid twenties. He was so hot, slight build, black hair and a nice black bush around his cock whick I jerked off for his several times. I never sucked him off in fact I never sucked anyone off until much much later in my 50's.
My job took me to another town a couple of time a month and I discovered an Service Area with a bathroom with 7 or 8 urinals in a bank, still without the modesty panels. I discovered many men with their erect pricks standing there. it was so exciting and any man so inclined could not help to get excited by it all. one day a man a little older than me asked me to follow him across the highway. He got in his car and I got in mine and I followed him to a cleared area under an overpass. We found a secluded area with cars passing overhead on the highway and he sucked me off and I jerked him off. He had red hair and like me he was uncut. An uncut cock really turned me on.
Another time I had to take the train to New York for business. I stopped in the restroom and lo and behold the long bank of urinals without the dividing panels. Again I am at the end. Every urinal was occupied, there must have been 18 or so. As far as I could see down, everyman had his cock out and erect. The guy next to me on my left leaned over and told me to pull my foreskin back so that others could see just how big the head of my cock was . He was fascinated with it. He had a nice cock himself, but then the guy next to him left and another guy came up. He was so fucking handsome and when he pulled out his already hard cock I nearly blew my load. It was so Hot! I looked at him, forgetting the guy between us, and we both started to jerk off in rhythm and we signaled each other and came off together. I now fantasized over him for many years.
There were many more exciting experiences at the urinals over the years, but one of the most exciting happened again in a theater. As time went on and the urinals were divided by modesty panels, there were fewer and fewer places that a guy could go and get a quick relatively safe thrill. But a few years back there was this hetero adult movie theater. It may have been hetero movies but that didn't stop us bi and gay men from meeting up now and then. The bathroom in this old theater had only 4 urinals banked together and thankfully there was no room for modesty panels. This one night I was the one of the urinals and this handsome Italian guy about my size that came right next to me. H e had just come from the outside and he was nervous. He looked at my cock, complimented me and got hard as a rock. He was 29 and married and erect his cock was 9 1/2 inches long and thick like mine He was so fucking hot! As I said he was nervous but very excited. he asked me to join him in the stall. When we got there he asked me to stand on the toilet so that if anyone came in they would only see one pair of shoes. he began to suck me off telling me how much he liked it it and needed it. He was also very scared and closeted. he wouldn't let me cum in his mouth and I didn't mind but I asked him to let me jerk him off until he came, which he did. I Jerked him off into the palm of my other hand because I wanted to feel the heat of his cum. We hugged each other for a long time and then we kissed. It was one of the hottest kisses i have ever had. he told me how much le lusted for his brother-in-law, his wife's brother. He siad his brother-in-law had a cock even bigger than his. I never asked and he didn't tell me but I often wondered how he knew.
I am now in my early seventies and am still closeted, and I still long for a hot man in my arms, to jerk him off, suck him , and kiss him passionately.
