My problem is that I no longer masturbate every day like I'm used to it. The reason is that the erection fails and not the sufficient stimulation to orgasm. Sperm production runs but still on high level, leading to tension and fullness in the prostate area. So I searched for a way to derive the semen as often as possible.
It looks like I have found with electrical stimulation, a method to achieve my goal.
I've bought a Vita Tronic TENS unit with the following technical data.
Output Voltage: idle: 0 to 80 V
With 500 Ohm terminating resistor
Pulse amplitude: measured at 500 Ohm terminating resistor, from 0 to 90 mA
(Max. output power)
Frequency: 1-250 Hz
With this device, I manage to trigger an orgasm.
I attach one electrode under the foreskin where my frenulum was (or I put up a metal rod into the urethra), and I shove the other electrode, insulated up to the front page in the anus. With this arrangement I can best stimulate the prostate.
