Although not strictly a chastity device have a look for a cock harness called the “Gates of Hell”. These are harnesses with a leather strap connecting a series of metal rings which encase your cock in a bondage caress. They usually have 5 rings and the biggest goes behind your cock and balls to keep the harness in place. This type of cock harness is inexpensive and can help introduce you to the feeling of having your penis wrapped in an erotic embrace – they can be a nice introduction to chastity. If you’re a little concerned about placing a metal ring around your cock and balls you can usually find the Gates of Hell with rubber rings too.
