For being called “rabbit” vibrators, only about half of this vibrator type has the small, soft, rabbit-style ears that give them their name. A more accurate name for this type of vibes would be dual stimulators – toys intended to provide both internal and external pleasure at the same time.
They have one smaller arm meant to stimulate the clitoris, and one larger arm that goes inside the vagina. Many rabbit-style toys also have internal portions that move in small circles, that have rotating beads on their shafts, both, or neither.
One of the best things about rabbit vibes is that they’re safe for anal use – the clit arm acts as a base or phalange, meaning that the toy cannot get pushed up too far or lost. However you choose to use it, rabbit vibrators tend to provide a lot of stimulation.
