The testicles are clamped between two acrylic plates. An electrode from the electrostimulation device is placed on the back of the testicles. The second electrode is fixed to the glans. Gradually the distance between the plates is reduced using the wing nuts and the current is increased. The current flows through the testicles via the vas deferens to the prostate and then through the corpora cavernosa to the tip of the glans. I can endure the procedure for a while. It ends in a wonderful orgasm, which I feel primarily in the prostate.
