Cock and ball torture

Cock and ball torture (CBT) is a sexual activity involving the application of pain or constriction to the male genitals. This may involve directly painful activities, such as genital piercing, wax play, genital spanking, squeezing, ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation, kneeing, or kicking.^[1] The recipient of such activities may receive direct physical pleasure via masochism, emotional pleasure through erotic humiliation, or knowledge that the play is pleasing to a sadistic dominant.

CBT can be performed using toys and devices.^[2]

Ball stretcher

A ball stretcher is a sex toy that is used to elongate the scrotum and provide a feeling of weight pulling the testicles away from the body. Intended to make one's testicles hang lower than normal, this sex toy can be potentially harmful to the genitals as the circulation of blood can be cut off if over-tightened.^{[citation needed]}

Most ball stretchers are leather, rubber, or stainless steel. Leather ones usually are fastened with snaps, wrapping around the scrotum with the testicles hanging below. Rubber ones stretch enough for the testicles to pass through, and can be either a tube or a ring, where multiple rings can be added to create the desired length of "stretch". The length of a stretcher can range from 2 to 10 cm (1 to 4 in).^[3]

Ball crusher

A ball crusher is a device that squeezes the testicles slowly by turning sets of nuts or screws.^{[citation needed]}

Parachute

A parachute is a small collar, usually made from leather, which fastens around the scrotum, and from which weights can be hung. It is conical in shape, with three or four short chains hanging beneath, to which weights can be attached.^{[citation needed]}

Humbler

A humbler is a BDSM physical restraint device, a cock-and-ball bondage toy used to restrict the movement of a submissive participant in a BDSM scene. It consists of a testicle cuff device, typically a ring, that clamps around the base of the scrotum while it is drawn back between the legs. This is mounted in the center of a bar or pair of rods that pass behind the thighs at the base of the buttocks. As a result, the wearer is forced to keep their legs folded forward, preventing the user from standing up straight, having to stay bent over or crawl on all fours.^[4]

Testicle cuffs

A testicle cuff is a ring-shaped device that can be placed around the scrotum between the body and the testicles. When it is closed it prevents the testicles from passing through. A common type of testicle cuff consists of two connected cuffs, one around the scrotum and the other around the base of the penis. A standard padlock may also be locked around the scrotum.^{[citation needed]}

Some passive participants enjoy the feeling of being "owned", while dominant individuals enjoy the sense of "owning" their partners. Requiring such an individual wear testicle cuffs symbolizes that their sexual organs belong to their partner. The cuffs may also form part of a sexual fetish of the wearer or their partner.^{[citation needed]}

Cock harness

Early cock harnesses were used to prevent erections in a variety of ways; many of them caused pain in the penis, typically using sharp projections from cock rings or sometimes via electric shocks. These devices were designed for medical use, to prevent ejaculation while sleeping which was believed to cause "seminal weakness" and other physical problems.^[5] An example was the jugum penis.^[6]

Ball busting

"Ball busting" is the practice of kicking or kneeing participants in the testicles.^{[citation needed]}

In Japan

Tamakeri (玉蹴り) (lit. ball kicking) is a sexual fetish and subgenre of BDSM within which a man's testicles are abused. The genre is also referred to as ballbusting ("bb" for short).^[7]

Denkianma (電気按摩) (lit. "electric massage") is a popular Japanese prank played between two people where one person puts their foot into the genital area of the other and shakes it in a vibrating motion.^[8] Often this is done by grabbing the other person's feet, raising them, and then placing one's own foot on their crotch and vibrating it. This is often done between school aged boys as a prank similar to kancho or as a type of bullying. In 2006, Frito Lay released a special, Taitsukun-themed edition of Doritos chips, that referenced denki anma.^[9]^[10]

Safety

Loss of blood flow is one of the greatest risks in cock and ball torture and may cause irreversible damage. Bleeding is an indicator of unsafe behavior. Because numbness may result from circulation problems in the affected member, the level of pain is not an indicator of a problem and signs of danger include numbness or loss of color and edemas.^[11] Bondage in which the testicles are tied to another object is especially dangerous, increasing the risk of damaging the testicles through excessive tension or pulling.

The most serious injuries are testicular rupture, testicular torsion and testicular avulsion, which are medical emergencies that require urgent medical attention.^[12]

Urethral fingering is an example of CBT needing special precautions, such as not having a sharp nail on the finger inserted inside the penis. Image shows a woman doing urethral fingering.
