I've never had a wet dream, I think because I've never gone without sex long enough to store an excess of the "stuff" a wet dream expels. It's a natural flushing function more than anything else.
I was having dry orgasms at a very young age, something I stumbled across while shimmying up trees in the woods, of all things. Sometimes it does pay to live an outdoors boyhood.
When I finally did have a discharge in my shorts one day while humping a tree, I suppose around 12 or 13, it shocked me. I thought I had broken something, or that I was ill!
But soon I learned all was well & normal, and quickly figured out that what I really needed to be doing was the jerking-off I had already heard something about (remember, that was about 1962, when lots of boys were seriously clueless regarding these things).
So I tried the manual method, and never went back to trees. Nor did I let up, rarely going more than a few days without draining my prostate for the rest of my life. I suppose a couple of weeks in US Army Basic Training was the longest at about 2 or 3 weeks, but even then not enough to prompt a wet dream.
And now I suppose that's a male thing I'll never get to have experienced in my life. Did I miss a lot?
