When i was 10 or so maybe younger. I was in the shower bathing. I was on my knees in the tub and my penis was laying between my thighs. I moved or something and I felt a sensation that felt good. So I started intentionally placing my penis in that spot and I would flex my back up and down causinga maturation affect between my thighs. Lol I never told anyone about this. I dont remember ever seeing any cum come out.
