Over the weekend I tried my PES electro stim again after a long time. With the balls, cock and rectal appliances on I was having intense feeling with half power on. Then I lay on my back which was even more intense and as I positioned the rectal probe against my prostate I had a very powerful hands free orgasm. It was great.
Hope others have had as much fun. Also it is not scary and you are always in control of the power and pulse rate.
