The bullet got its name because of its shape, which is generally like a bullet such as found in a gun or rifle.
They come in different sizes, colors, materials, and in some variety of shapes, and are typically used to stimulate the female G-spot, clitoris, or anus, during foreplay or masturbation.
A bullet typically causes vibrating sensations, which can lead to an orgasm. Bullets may also be used on other parts of the body, such as the nipples, inner thighs, or perineum.
The controls to activate and operate the device may be on the bullet, but others have remote control options, either wired or wireless. The controls are used to make for different speeds or different movement patterns.
