Wow, I want to try that. How did it feel? I've felt my urethra flutter when I'm swapping piss in and out of my bladder especially at high pressure and flows, sometimes if a hose end or fitting moves off center down my tube, it contacts my urethra wall suddenly stopping flow altogether then backing up. Once it builds enough pressure and starts gaining momentum from all the way inside the top back of my bladder, it flows again. Usually it's fluttering super fast maybe 3-5 cycles/second, almost making me cum. But just reading your words, "pissing under current..." that sounds erotic. It's next up for sure. thanks!
