The insertable electrode I like to use in my urethra is bipolar- you can see the two metal bands which send current through my sensitive flesh- but its cord has two connectors. This makes it possible to use just one of those contact points, and complete the circuit with a sticky electrode just above my clit. Electrically connecting my peehole with my clit feels amazing! I turn the power up until I almost can't take it anymore, and then begin using a pinpoint vibrator on my big clit so that I can turn the estim up even higher. A vibrator on my clit often does wonders to help me turn pain into pleasure! When I'm at the very edge of orgasm, I take the vibrator away, but that doesn't ruin my orgasm like it usually might... instead, the estim keeps me cumming for a long time, but it becomes an intensely painful climax. After my contractions fade, I turn off my electrostim power box, then pull the electrode out of my urethra. Pee spurts out around it as I do, and then I spread my pussy and have a nice long piss.
