away from the body. This can be particularly enjoyable for the wearer as it can make an orgasm more intense, as testicles are prevented from moving up. Intended to make one's testicles permanently hang much lower than before (if used regularly for extended periods of time), this sex toy can be potentially harmful to the genitals as the circulation of blood can be easily cut off if over-tightened. While leather stretchers are most common, other models consist of an assortment of steel rings that fastens with screws, causing additional but only mildly uncomfortable weight to the wearer's testicles. The length of the stretcher may vary from 2.5–10 centimeters (about 1–4 inches). A more dangerous type of ball stretcher can be home-made simply by wrapping rope or string around one's scrotum until it is eventually stretched to the desired length.

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, as any attempt to straighten them even slightly pulls hard on the scrotum, causing anything from considerable discomfort to extreme pain. In this way the wearer is prevented from standing up straight and has to stay bent over or crawl on all fours.

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. Testicle cuffs are one of the many devices that are used to restrain the male genitalia. A standard

of the wearer or their partner. However, these are extreme uses of testicle cuffs. More conventionally, the device pulls down the testicles and keeps them there during stimulation, which has a number of benefits: * Making the penis appear longer. Pulling the testicles down and away from the base of the penis stretches the skin over the base of the penis and pubic bone, exposing the additional few centimetres of penile shaft that is normally hidden from view. * Improving sexual arousal. While some participants may be aroused by the feeling of being "owned", the physical feeling of stretching the ligaments that suspend the testicles has an effect similar to the more common practice of stretching one's legs and pointing the toes. * Preventing the testicles from lifting up so far that they become lodged under the skin immediately adjacent to the base of the penis, a condition which can be very uncomfortable, especially if the testicle is then squashed by the slap of skin during thrusting in sexual intercourse. * Delaying or intensifying ejaculation by preventing the testicles from rising normally to the "point of no return". It is much harder to reach an orgasm.

—mainly women—are participating in it. The dynamics of tamakeri consist of a masochist having their testicles hurt by a sadist. The fetish is popular among heterosexual and homosexual men and women. 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. 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 and could be seen by a western audience as a type of bullying. In 2006,

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. 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,
