(CBT) is a sexual activity involving torture of the male genitals. This may involve directly painful activities, like wax play and genital spanking, but it may equally consist of the use of cock harnesses, testicle cuffs, parachutes, prolonged stimulation (teasing), not necessarily leading to orgasm. Erotic electrostimulation is often used in CBT.The use of ball bags, various chastity devices, and the humbler can also be regarded as forms of CBT.
A cock harness is a more elaborate harness designed to be worn around the penis and scrotum. Its intention is similar to that of a cock ring.
A testicle cuff is a ring-shaped device around the scrotum between the body and the testicles such that when closed it does not allow the testicles to pass through it. A common type has two connected cuffs; one for the scrotum and one for the base of the penis. They are one of many different gadgets for restraining the male genitalia. They are not to be confused with handcuffs, which have a more widespread use in restraining the hands and wrists.
Historically, testicle cuffs may have been used by the slave traders of Western Africa, as a means to subdue newly-captured males. In processions to markets, the males were bound to each other in single-file formation, usually by the hands, with ankle manacles in place. The testicle cuffs extended between the legs, and each man was connected to the next by a rope between their genitals. These tight metal bindings on their scrotums were to ensure that a quick pace was kept, for if a man were to stop walking the rope would pull and cause quick, sharp pain in the genital region.
Erotic electrostimulation (also known as E-stim or electrosex), is a human sexual practice involving the application of low current electricity to the body using a special apparatus (such as a TENS unit or Violet wand) for purposes of sexual stimulation. Erotic electrostimulation has been particularly associated with BDSM activities, although its use is becoming more "mainstream." Different sorts of electrodes are used for erotic electrostimulation, such as specially designed vaginal plugs, vulval skin electrodes, anal plugs, cock rings, catheters, cock-and-ball torture (CBT) boards, etc. Electrodes usually require an electrically conductive gel to be applied before use. A large variety of devices are available.
A ball bag is a soft ball-shaped device that encloses the penis and testicles.Ball bags intended for bondage play are typically made of leather, PVC or rubber. The opening of the bag typically has a strap drawn tight around the base of the testicles and may feature means for locking. Most ball bags are large enough only to acommondate a flaccid penis and are designed to make erections uncomfortable. Some models incorporate weights for stretching the genitals.Some male sadhus (or ascetics) of the Vaishnava branch of Hinduism wear as a symbol of austerity an arbandh, or a metal ball bag slung on a girdle about the waist.
A chastity belt is a locking item of clothing designed to prevent sexual intercourse and possibly masturbation. The purpose may also be to protect the wearer from rape or temptation. Devices have been created for males and females.The use of such devices against another's will would now be considered abusive in most western societies.The term "Chastity belt" is also used metaphorically in modern English to mean an overly protective device or practice. The term carries a derisive connotation and may also imply that the subject is antiquated.Today, chastity belts are sometimes used in consensual BDSM play and as provocative items of fetish wear. They range from simple leather or plastic toys commonly sold by adult stores to expensive high-security steel devices made by a handful of specialist firms.Although no reliable statistics are available on the use of chastity belts, anecdotal reports from manufacturers suggest that most belts sold are for men.Modern, high-security chastity belts tend to be one of two types:
- A "cage"-type device which encloses the male genitals, intended to prevent stimulation and erection. "Metal-detector safe" models made entirely of plastic and may be fastened with tamper-evident plastic seals.
- A "Florentine"-style belt (named after the Bellifortis reference) has a band around the waist or hips, with a "shield" running between the legs to cover the genitals.
For Florentine belts, the design must accommodate a long-term wearer's needs to pass both urine and feces:
- For females, the shield is commonly a flat band with a slot through which the labia can protrude and through which urine can pass. (Some manufacturers fit a perforated cover—sometimes called the "secondary shield"—over this slot to prevent the wearer from being pinched when sitting.)
- For males, the shield usually covers a tube in which the penis is held facing downward with perforations at the bottom of the shield to allow urine to escape.
- Belts with a "thong" arrangement have a single strap running up between the buttocks to the waistband. On some, this is a plastic-coated cable or a thin curved metal rod; on others, it is a steel strap with an aperture over the anus to allow passage of feces.
- Belts with a "V"-arrangement have a pair of chains attached together the bottom of the shield and apart towards the back of waistband in a "V" to leave the rear open.
Most modern chastity belts are fastened with padlocks. Some high-security designs nest the lock within a shroud to make it more difficult to attack with bolt cutters. Some of the more expensive designs have locks that are integrated into the belt.Modern chastity devices of both cage and Florentine types may also be designed to be work with genital piercings for greater security.
A humbler is a BDSM "cock and ball torture" and physical restraint device used to restrict the movement of a male participant in a BDSM scene.The humbler consists of a testicle cuff device that clamps around the base of the scrotum, mounted in the centre of a bar that passes behind the thighs at the base of the buttocks. This forces the wearer to keep their legs folded forward, as any attempt to straighten the legs even slightly pulls directly on the scrotum, causing considerable discomfort.Note: because of the strong muscles and substantial mechanical advantage of the legs, this device can cause permanent physical damage if not used with caution. Damage can also occur if worn for an extended period of time -- all the other dangers of the use of testicle cuffs and other forms of physical restraint also apply here.
