A
nipple clamp is a
clamp that can be applied to the
nipples of any type of body. It is a
sex toy which can be attached to the nipples to create pain by restricting blood flow from erect nipples by applying pressure to them. Some people derive erotic pleasure from seeing nipple clamps applied. They are used in some
BDSM activities, such as
tit torture. The use of nipple clamps is often portrayed in the media as
deviant or
kinky sexual behavior.
