A TENS unit was one of the things that I tried unsuccessfully for my delayed or non-existent orgasm. There were electrodes on straps that I fastened high and low on the shaft of my penis, but shaft wasn't very long and never really got the pulsing low volt electrical charge. I think I tried under the testicles with one but never succeeded. I guess it was a case of user error. Glad to hear it works for you.
