Bondage Ball Stretchers, Cock Cages and Chastity Devices

A popular type of chastity device for men is commonly refereed to as a chastity cage, penis cage, cock cage or chastity tube. Cock Cages are almost exclusively used as a sex toy and in BDSM play, and may enclose a man's penis in order to make an erection impossible if the man becomes sexually aroused, and prevents sexual intercourse, masturbation and oral sex. A Cock Cage can also be combined with other sex toys like a shock collar or a ball spreader if you are game.

Most Cock Cages consist of a ring seated around the base of the penis behind the scrotum and a cage that holds the penis, with the two parts mating together with a hinge or pin. When the cage is locked, the testicles are trapped in the gap between the ring and the penis cage which is narrow enough to prevent the testicles and penis from being pulled out.

The testicles are usually held in a fixed position, exposed beneath the cage but some designed can also come with an additional cup that prevents easy access to the entire genital area. 

Most Cock Cages prevent the user from physically touching their genitals but they usually do prevent masturbation. Cock Cages may hold the penis firmly but they may also be loose and, although intercourse is rendered impossible, they may make manual stimulation even to orgasm, a possibility.
