Erotic electrostimulation (abbreviated erotic e-stim[1] 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.
[3] A few cases of accidental death as a result of autoerotic electrostimulation have been reported in the forensic science literature; the cases reported involved mains-powered, self-made devices, with current passing through the chest intentionally (usually via nipple stimulation) or unintentionally (for instance, touching an energized part with a hand).
[4] In one case reported in the press, a man from York, Pennsylvania was sentenced to 20–40 years in prison for third-degree murder and reckless endangerment after killing his wife with electrostimulation to her nipples directly from a power strip plugged into the mains.
Such power sources[dubious – discuss] are still in medical use today and are known as EMS (electrical muscle stimulation) units.
In the 1970s, experimenters noticed that bare speaker wires could deliver a jolt and began using recorded and live sound for electrostimulation.
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.
Though lacking in options compared to the more expensive specialized units, these have proven to be an inexpensive method for entry level practice.
For example, a transient over-voltage on the mains input can damage the isolation of the transformer, resulting in the output terminals becoming live.
There are other medical methods that have led to patent filings, such as the discovery that placing electrodes in the spinal cord can induce pleasurable feelings leading to orgasm.
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.
