A vibrator is any toy that uses a motor to oscillate against the body. That umbrella covers bullets, wands, insertables, wearables, and machines that happen to buzz as well as thrust. The useful distinctions are where the motor sits, how strong it is, and whether the surface is pleasant for the skin it will touch.

Motors differ. Some rumble. Some whine on the surface and fade internally. People who like pressure often want a wand-style rumble. People who go numb on rumble sometimes prefer a higher, lighter buzz or air pulse instead.

Buttons should be operable with a slick thumb. A travel lock saves embarrassment in a bag. Charging and cleaning depend on seals. If you remember only one habit, make it this: wash the part that touched the body before the lube turns to glue.

Buying the first one

• Pick one job: external, internal, or wearable.
• Quiet enough for your walls.
• A shape you can hold for ten minutes.
• A maker who sells replacement chargers.
