I too love to cum without hands using electrical stimulation. I insert one electrode into the anus directly on the prostate, together with an anal plug. The other one is attached to the head of my penis. I can come several times in a row. It feels amazing
Where were you able to get the metal screw extenders? I have a similar device but need to find different length extenders. The two pairs that came with it are too short and too long. I need something inbetween..
