Learning how to do it for the first time.
It was shortly after my 14th birthday in the '50s that I experienced my first wet dream. I don't remember thinking there was anything odd about it, though no one had told me about such things. By the time I was 15 I was having these nocturnal emissions about three times a month, usually when dreaming about some girl at my school. I used to fantasise about holding girls' breasts, and it was often while dreaming of this that I felt my penis throbbing and awoke to find a sticky mess on my pyjamas. By then this was happening as often as once a week, but one day while walking home with my friend Peter, wheeling our bikes, he suddenly asked 'Do you toss off?' I'd overheard this expression before, and assumed it referred to wet dreams, but he told me how he could make it happen himself.
'You just start rubbing', he said, 'and your whole body starts becoming tense and it gets more and more exciting: you feel you just must go on, until suddenly it all comes'. I thought this sounded very exciting. I had previously experimented with urinating through a toilet-roll tube, though already my cock was so big that it wouldn't go in, and into a milk bottle, but I hadn't cottoned on at all to the idea that it was sperm I should be expelling instead. Looking back, I wonder how long it would have taken me to satisfy this need to put my cock inside something, if Peter had not told me.
I was still rather self-conscious at the idea of grasping my whole penis in my hand, so in bed that night I lay on my back and tentatively stroked the underside (now uppermost because of my erection) with two fingers on the softest and most spongy part. It did become more and more tense and exciting, producing a feeling never felt before.
Eventually there was a great searing feeling followed by several fierce throbs as the sperm jetted out of me.
How I wished, and still wish, that I had discovered this long before. When I reported back, Peter encouraged me to use my whole hand next time (demonstrating the technique on the handlebar of his bike), and since then I've never looked back.
For some months after that, we enjoyed mutual sessions, but I'll tell you about those later.
