Electrodes
An electrode is used to deliver the actual electrostimulation to the body.
For erotic electrostimulation, these are typically items designed to be applied to the genitals such as vaginal plugs and shields, anal plugs, probes to directly stimulate the prostate, testicle rings, CBT boards, cock rings, urethral probes, and other items for penile application. The pads used with TENS units are also used in the sexual application of electrostimulation. There are also electrified nipple and breast electrodes available, but there is disagreement within the e-stim community about their safety.
The electrodes can be made of metals such as gold, silver, aluminum, and stainless steel. There are also electrodes made out of conductive silicone. Conductive rubber is a cheap, flexible and efficient option.
