Has anyone else used a TENS unit while masturbating?

I have a TENS unit that I got for my back and curiosity has gotten the better of me. My wife is out of town, I can't find anyone to play with, and I have the house to myself. So why not get naked, attach my TENS unit to my lower region and edge ALL night. I put a pad on each side of my balls where the pit of your leg is and I put another 2 pads on each side of my hole. The sensation is amazing. Depending on where I am in my edge and which TENS cycle I'm using, when there's a long electrical squeeze, it forces some cum out. Which I quickly lick up. I'll keep trying different pad placements and different cycles to find new sensations. This would be an amazing feeling with a cock in me.

Who else uses there TENS unit to treat their ailments?
