The first time I experienced seeing another boy’s cock was when I was really young, maybe 7 or 8. Me and my friend who was a year or two older than me used to play a game which basically involved us showing each other our cocks and bums. We would play this game when alone in his room or when we used to go into the woods to play and build camps and such. This is before anything sexually motivated, purely just kids being silly and inquisitive.
Later on, at maybe 11 years old a new girl called Sarah moved in near us. She was the same age as my friend I think, definitely at least a year older than I was. We used to show her our cocks and in return she used to lay on her bed and show us her fanny (in the UK fanny means vagina). She used to let us touch it and vice versa. Again, this is all before I hit puberty so there was never any sexual element to it.
Moving on, when I was about 15 I had another friend who was a year or so younger than me. I had a major secret crush on my friend, but this is way before I knew I was properly gay or had even admitted to myself that I was gay, I just knew that I liked him. One day we sneaked into the local park. It was a huge park and they used to have concerts there. This concert was Spandau Ballet, we were sat under a walkway on some benches, we were both drinking cider which we had somehow obtained and were both drunk. I cannot remember how it happened but somehow we ended up with our cocks out and wanking. I remember touching his cock and thinking it was small compared to mine, not that I was big, just that he wasn’t as developed as I expected him to be at 13 or 14.
Over the next couple of years we wanked a couple of times together but it was never pre- planned, each time we were drunk and it was always a little awkward. The last time was when I was 17 and had just bought my first car (but couldn’t drive it yet).
He's now married with kids but we haven’t seen each other for many years.
