They are the most versatile bullet vibrators because they can reach spots other vibrating bullets cannot reach. For example, one-touch bullet vibrators are wireless and small, they cannot be inserted into the body.
Bullet and egg vibrators that have wires cannot be used during anal sex because the rectal wall muscles may grip too tightly and remove the bullet from the wire. If you wish to stimulate the g spot, a bullet on a wire cannot easily be placed in the g spot area within the vagina.
