A ball lock, or nut lock, is the technique of fastening a padlock around the male scrotum between the penis and testicles. When sized correctly it will allow circulation and freedom of motion, but cannot be removed from the scrotum without being unfastened.
The opening of a typical padlock is approximately 1" x 1" (25mm x 25mm) or 1/2" x 2" (13mm x 50mm). A keyed padlock or combination lock may be used.
The ball lock may be applied to the subject in a standing, sitting or lying position. For some couple play, where the male subject has been restrained in a spreadeagle position, the padlock may be unexpectedly fastened around the scrotum. This situation creates a predicament for the subject, knowing that lock could remain in place indefinitely, securing his testicles entirely at the will of his partner.
In recreation, the choice of a key or combination release provides different options for negotiating release of the testicles. For a lock with two keys, one key is used while fitting the lock around the scrotum. The second key may have been hidden in advance. Once the lock has been fastened, the first key may be disposed of or damaged beyond use, leaving the hidden key as his only means of release. In the case of a combination lock, the combination may be withheld and delivered at a later time from a remote location, such as by telephone or mail. If negotiation or play continue over a prolonged period, the subject may never know when the ball lock will be released.
If the weight of the lock becomes tiring to the scrotum and testicles, it may be supported by undergarments such as briefs or a jockstrap. This relief may extend his predicament when the key holder knows there is no discomfort for the testicles.
A leash can also be added to the lock for additional control over the subject.
The popularity of a ball lock in some relationships may be attributed to the padlock being an ordinary household item. Once fastened around the scrotum it can be concealed under clothing for prolonged wear. It allows full freedom of movement and function of the male genitalia, is painless, yet is permanent until deliberate release by the key holder. Given these features, its use may go on for hours, days or even weeks.
Some women may enjoy the control it offers and use the technique as a way to modify behavior of a male partner. The key holder is his only means to release. Without the key or combination in his control, the male has no way to remove the padlock himself, and he may feel that his genitals are owned by his partner. An added pleasure for a female key holder is knowing this technique is unique to the male anatomy.
While a ball lock does not offer physical chastity, because the male genitalia remains functional, it may be seen as providing emotional chastity against promiscuity.
Due to the delicate physical nature of the scrotum and testicles, care must be taken to not cause injury. When fastening the lock, the scrotum should not be pinched. After fastening, circulation must be maintained and monitored. During wear, care must be taken that the padlock is not caught or moved in a way that will be hazardous to the subject. Damage can also occur if worn for an extended period of time. Other dangers of the use of physical restraint may also apply to this technique.
