Oral stimulation of nipples is a human sexual practice. Typically, one person will orally stimulate the nipples of another person. The stimulator may lick, suck, or bite the other person's nipples. The practice may be performe upon—or by—people of any sex or gender. Some people are able to perform oral stimulation upon their own nipples. Oral stimulation of nipples can be a form of foreplay. Some females and even some males experience breast orgasm without other forms of sexual stimulation.
