A chastity cage encloses the penis in a short barred or solid sheath, locked to a ring behind the scrotum. The idea is to block erection and direct stimulation while still allowing urination through a slit or gap at the front.

Resin, coated steel, and 3D-printed nylon dominate current designs. Sizing depends on flaccid length and the ring diameter that passes over the testicles without crushing them. A cage that is too long lets the penis slide and rub. One that is too short bites at the glans when any arousal hits.

Hygiene is daily work. Warm water through the bars, a soft brush, and dry skin afterward prevent odor and fungal trouble. Night erections will test the fit. Pain that wakes you is a sign to unlock, not to tough it out for a keyholder’s story.

Fit and care

• The ring should not leave a deep mark after an hour.
• Keep a spare key with a trusted person or in a breakable seal.
• Hair can catch in hinges; trim or use a guard.
• Stop for color change, numbness, or difficulty urinating.
