This reminds me of me when I was a teen. I learned how easy it was to piss in the shower when my 14 y.o. straight-up rock hard morning piss-hard erection was IMPOSSIBLE to bend down far enough to piss in the toilet. So I just pissed in the shower, creating quite a high "fountain" of piss. And, of course, like most teenage boys, I found the shower to be a great private time to jerk off.
