Erotic electrical stimulation, also known as electrophilia or electrosex, is the sexual practice of applying low frequency electrical stimulation to the nerves of the body and with particular emphasis on the genitals, anus and breasts. This is achieved by using a power source such as a TENS, EMS, Violet wand or a made-for-estim play unit such as the Rimba Electro Stim Power Box. Electro stimulation, or estim, has been associated with BDSM torture or kinky sex and erotic electro stimulation is an evolution of that practice. Erotic electro stim or e stim is the use of stimulation electrical devices in an erotic or sexual manner as apposed to the more sadistic or painful applications in BDSM, sadomasochism or electro torture.
