A nipple clamp is a type of sex toy that is applied to a person's nipples to pinch them. Varieties of nipple clamp include clothes-pin-style, tweezer and clover. Nipple clamps are used to cause pain in the nipples as part of certain BDSM activities. They are also used to produce erotic stimulation as part of nipple play. In this context they are not primarily used to produce pain but rather to increase nipple sensation. Their use traps blood in the nipples, increasing the sensitivity of the nipple. The sexologist Carol Queen says that "clamps are also very useful for hands-free nipple play".

Breast torture is a BDSM activity in which sexual stimulation is provided through the intentional application of physical pain or constriction to the breasts, areolae or nipples of a submissive. It is a popular activity among the kink community. The recipient of such activities may wish to receive them as a result of masochism or they may have a desire to please a dominant who is sadistic. Those involved may also be motivated by breast fetishism. Mild breast torture such as light impact play on the breasts is also occasionally used outside of the BDSM context to provide stimulation and pleasure during conventional sex. While breast and nipple torture is usually performed on women, most techniques or methods may also be used on men.
