E is for Electrostimulation
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 behaviour 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.
F Is for Foot Fetishism
Foot fetishes are one of the most common fetishes out there, especially for heterosexual men. Someone with a foot fetish is literally turned on by feet—thinking about them, touching them, seeing them—and could potentially get off on everything feet. They often want to engage in foot worship, in which they treat their partner’s foot like a holy object: kissing, caressing, and massaging it. So even if you don't have a foot fetish, having a partner with one can be extremely enjoyable as it means there are potentially foot massages galore in store for you. But like all kinks, foot fetishes exist on a spectrum. Humiliation can also play a strong role in a foot fetish: The fetishist may want feet shoved in their face and mouth, or to have their partner walk all over them, touting how filthy their feet are and how pathetic the fetishist is to enjoy such an activity. Other foot fetish activities include giving pedicures and smelling the feet or shoes that said feet reside in throughout the day.
