Female chastity belt
Modern chastity belts for women generally follow the traditional "Florentine" pattern (named after the Bellifortis reference), with a band around the waist or hips and a "shield" that runs between the legs to cover the genitals.
Modern belts usually are made with features and accessories to accommodate erotic fantasy and BDSM play. For example, a slot in the shield may hold a dildo inside the wearer's vagina, which cannot be removed except by the keyholder. Some have a perforated cover (sometimes called the "secondary shield") over this slot to prevent the wearer from being pinched when sitting. The cover may also prevent direct masturbation by preventing access to the labia. Anal shields which forcibly retain butt plugs inside the wearer are a common accessory. The shield can be designed to work with genital piercings for greater security.
Female chastity devices are in demand, but sanitary constraints keep them from being practical for long term wear. On belts intended for long-term wear, the shield must accommodate the wearer's hygienic needs:
- The shield is commonly a flat band with a slot through which the labia can protrude to breathe and through which urine can pass.
- Belts with a "thong" arrangement have a single strap running up between the buttocks to the waistband. This may be a plastic-coated cable or a thin, curved metal rod, and there may be an opening in the thong to allow defecation.
- Belts with a "V"-arrangement have a pair of chains or cables attached together at the bottom of the shield and apart towards the back of waistband in a "V" to leave the rear open.
Male chastity belts
Chastity belts of the so-called Florentine type also exist for men. As in the standard Florentine design, a circular horizontal band encircles the waist and a shield is attached to the front of the waist belt. The shield extends downwards to cover the genital areas of the wearer and is attached to the back of the waist belt. For male belts, a penis tube is secured behind the front shield. In some designs, the testicles are covered by special cages. Most high-security chastity belts are made out of stainless steel, although fiberglass composite belts have also been made. Most belt designs are secured with padlocks. For travel a plastic device with a numbered plastic seal. The more secure designs have their padlocks' shackles hidden to make cutting the shackle difficult or impossible. Male devices are mostly external and the ability to make them secure makes them more popular.
