Chastity piercings are types of genital piercings that can be used to impose chastity in males and females.
Females
A ring or other device is used to hold the labia closed, preventing the wearer from having vaginal sexual intercourse. When denial of direct stimulation of the clitoris is the goal, a rigid shield can be fastened over the clitoral area with labial piercings.
Males
In males, chastity piercing can be performed several ways. Through infibulation (piercing the foreskin closed), a Prince Albert or frenulum piercing using a smaller gauge locking mechanism (preventing intercourse), or chaining a Prince Albert piercing to a guiche piercing (thus preventing an erection). More commonly, a piercing can be used in combination with a chastity device to anchor the penis within the device and prevent it from being pulled out the back. The Prince Albert is the most popular piercing for this purpose.
