Erotic Electrostimulation - History

History

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 Relaxacisor, 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 Relaxacisors 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 (such as the ErosTek 312) 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.

Research into general electrode massage units, using accupuncture points, has come up with the point SP6 (spleen 6) as a key point likely to stimulate a woman to orgasm, electronically.
