I first started masturbating aged 11 in the 1st week of Secondary School.
As with most boys, I can't remember a time in my life when I've not had a fascination for anything sexual, so when there was some obvious degree of excitement around the boys' toilets at school, with talk that one of the boys was going to have a wank, although I had no idea what it meant, I was keen to find out.
Sure enough he demonstrated his magic in front of all the other boys, and at the end of the day I headed home with all the speed I could muster, went straight to my room, stripped & began to mimic what I had seen earlier.
Within seconds I latched onto the pace required & was amazed that I hadn't discovered how good this could feel earlier. I then reached the point where I was certain I was going to pee all over the place, but as it felt so uncontrollably good I thought "what the hell, I'll clear it up later", and then exploded into my first ever orgasm.
The very next thing I did was to get dressed & go call for my best friend, who lived across the road, where I taught him the new skill, after which we used to masturbate together many a time - often with other friends in the group as well.
Now, 40+ years later, I'm still as keen on masturbating as ever I was, although over the past week, due to having to undergo a circumcision for medical reasons, I'm currently having to relearn the best techniques of how to masturbate all over again. It's like reliving puberty.
