Chastity

In kink, chastity means locking the genitals in a device — typically a cage — so the wearer can't get hard or get off without the keyholder's say-so. The whole charge is in the denial: handing over control of your own orgasm to someone else. Common in D/s and femdom dynamics, where the keyholder decides if and when you're 'unlocked.' Tease and denial, dialled up and made literal.
