I vaguely recall experimenting with touching myself when I had a boner, without really knowing what I was doing or having a name for it like ‘masturbation’ as I understand it now. I believe I entered puberty within a year or so, because I had wet dreams and had pubic hair although my dick was a little boy’s tool, maybe 3″ in erection.

It’s like this:
You’re turned on.
You start stroking it.
You don’t really feel anything.
For a while, it’s just methodical stroking.
Finally, you “get into the groove”. It becomes natural, organic, you don’t want to stop.
And Cummm.
