An neighbor boy who was/still is 5 yrs older...he was probably 13 at the time...and somehow we found ourselves alone at his house and he asked me if I wanted to see something. So he took me in the bathroom and started beating himself off and after a minute or two he said watch this...w/out changing expression or breathing any harder or different...he aimed his cock at the toilet and shot 4-5 jets into the water. I thought it was pretty cool, but didn't really have a clue except that was something you were able to do when you got older.
So by the time I finally got my stuff, I knew what to expect. I was probably 12 when I stopped shooting blanks and came for real. I'm sure it was alone in my bedroom.
