Cock-and-ball torture (CBT) refers to the sexual practice of inflicting pain or discomfort on the penis and testicles. This practice usually occurs during BDSM play involving a dominant female and a submissive male. The scrotum and penis are packed with nerve endings, making them extremely sensitive to all types of handling. Although some people can hardly stand the thought of cock-and-ball torture, others find the practice highly erotic and very pleasurable.
Loss of blood flow to the penis or testicles is the greatest risk of CBT and can cause severe and irreversible damage. As such, CBT should be practiced with consent, care and education around potentially dangerous outcomes.
Cock and ball torture may also be referred to as cock bondage.
