Electrostimulation involves using the power of electricity—aka getting an electric shock—for kinky, sexy fun. Obviously, getting shocked can be dangerous, so electrostimulation begins to get into another type of kink called "edge play," which refers to risky BDSM behavior that runs the potential of doing actual bodily harm. Electrostimulation is part of CBT ("cock and ball torture") sessions in which a domme shocks her sub's genitals by rigging them to electrical contraptions—typically either a wand (see "Z" on this list) or a system that stimulates nerve endings called a "transcutaneous electrical nerve endings stimulation" unit—that can be purchased from specialty kink shops. This is one of those preferences for which you need to be extremely careful to take the correct safety precautions, use an ironclad safe word, and obtain continuous, enthusiastic consent.
