Sexual practice

Erotic electrostimulation (abbreviated erotic e stim and also known as electrosex) is a sexual practice involving the application of electrical stimulation to the nerves of the body, with particular emphasis on the genitals, using a power source (such as a TENS, EMS, violet wands, or made for play units) for purposes of sexual stimulation. Electrostimulation has been associated with BDSM activities, and erotic electrostimulation is an evolution of that practice.

The use of electricity for entertainment purposes dates back at least as early as the 1740s. In the 1830s, insertable electrode attachments for small magnetos could be purchased. Later in the 1800s, various electric belts (some complete with "suspensory sack") were advertised as cures for impotence. In the 1920s, the American Medical Association investigated such devices, and concluded that they provided "more or less mechanical masturbation". Modern electrostimulation first became recognized during the 1950s with the introduction of a device called the Relax A Cizor, which was originally designed to stimulate the muscles of a relaxing subject using electric currents as a means of "passive exercise". Such power sources are still in medical use today and are known as EMS (electrical muscle stimulation) units. Some people soon found alternative uses for the Relax A Cizors by placing the contacts on sexual parts of the body. By the 1970s, medical TENS (transcutaneous electrical nerve stimulation) units were also being used for electrostimulation. In the 1980s the first devices manufactured specifically for erotic electrostimulation became available, in particular the Titillator and the Pleasure Box, later known as the PES Power Box. In the 1970s, experimenters noticed that bare speaker wires could deliver a jolt and began using recorded and live sound for electrostimulation. At that time, there were no professionally made attachments for such play, so people built their own out of copper plumbing parts and other metal pieces with attention to resistors placed in series with the human parts to control the current for safety. Although early e stim units used only a simple, pulsed, sinusoidal wave, newer units use more complex wave forms and also allow for the use of ambient sound or prerecorded wave forms like music or specially designed computer files for specific types of stimulation. There are now sites dedicated to the creation of MP3 files specifically for erotic journeys or symphonies, which can include such routines as rewards, punishments, very strong, and pleasantly soft portions.

There are repackaged TENS and EMS units marketed as erotic electrostimulation power sources. EMS units are designed to cause muscle contraction.

An increasing number of "body toner" or "electromassage" type power sources are being marketed directly to consumers. Though lacking in options compared to the more expensive specialized units, these have proven to be an inexpensive method for entry level practice.

Some people craft "homemade" electrostimulation power sources, or adapt or modify commercial products (such as a Hifi or DVD system) that were never intended for electrostimulation of the human body. These can be dangerous practices; such improvised devices not specifically designed for use on the human body can easily cause injury. There are also various apparatuses, with external or internal stimulation. U. S. patent 3,941,136: "Method for artificially inducing urination, defecation, or sexual excitation". U. S. patent 4,585,005: "Method and pacemaker for stimulating penile erection". Other kinds of apparatus use interferential currents with four surface electrodes to replace the internal electrodes.

An electrode is used to deliver the actual electrostimulation to the body. The image of the woman receiving electrostimulation shows a deprecated practice. Placing electrodes anywhere on the chest is risking current passing through the heart, which risks cardiac arrhythmia or arrest. The general rule for electrostimulation is 'only below the waist'. For erotic electrostimulation, these are typically items designed to be applied to the genitals such as vaginal plugs and shields, butt 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 while there is disagreement within the e stim community about their safety the most commonly held consensus is 'only below the waist'. 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.

Violet wands were originally electric and neon testers, but are now split into two types: mechanical (Tesla Coil), and solid state wands. They are used for the application of low current, high voltage (min 35 kV to max 65 kV typically), high frequency electricity to the body, as such they are most commonly used in BDSM for erotic sensation play. Violet wands can deliver a variety of sharp, cutting, or piercing type sensations. A violet wand typically consists of a hand held "wand" made of plastic case which encases the mechanical (Tesla coil) or solid state components; a power cable, a collet (7/16" in the United States, 11 mm in Europe), and a cone. The collet is inside the cone end of the violet wand and is where glass and metal probes are inserted to be used with the wand. The cone is there to prevent sparks jumping from the collet directly to subject. Violet wands can be used anywhere on the body but should not be used around the eyes.

Skin electrode gels play an important role in the success of erotic electrostimulation since without it, there is a greater risk of high current skin burning. Water based lubricants are generally recommended. Typically it is recommended to avoid any lubricant that contains silicone since it is an insulator and hence reduces conductivity. Practitioners of electrostimulation select lubricants for compatibility with the material of the electrodes, as well as for desirable conductive properties, which can maximize the strength and quality of the signal.
