CB-X

CB-X is the world's leading male chastity device brand, producing the most widely used and trusted polycarbonate and silicone chastity cage systems available. Founded in the United States, CB-X manufactures the CB-6000 and CB-6000S series, the CB-X Curve, the Bon4 silicone cage, and a full range of spare parts and accessories that have made the brand the reference point for male chastity play for over two decades. The CB-X range at Lovva covers the brand's core cage systems, sizing kits, and accessories for solo chastity practice and partner-controlled power exchange dynamics.

About CB-X

CB-X built its reputation by solving the most fundamental problem in male chastity device design: how to make a cage that is simultaneously secure enough to prevent erection and orgasm, comfortable enough to be worn for extended periods without injury, and practical enough to be fitted correctly without specialist knowledge. The CB-6000 addressed all three requirements in a single polycarbonate cage system that included five sizing rings and four spacers, allowing the wearer to work through combinations to find a precise, secure, and comfortable fit.

Before CB-X, practical chastity options were limited to uncomfortable metal devices that required precise professional sizing and caused problems with extended wear, or improvised solutions that were neither secure nor safe. The CB-6000 changed this by putting a systematic sizing approach directly in the buyer's hands, and the result became the most recognisable chastity cage in the world. The CB-6000 remains the benchmark against which all other chastity designs are evaluated, and the CB-X product family has expanded around it to serve different anatomy types, wear preferences, and experience levels.

For Australian buyers, CB-X products at Lovva represent the most reliable and well-supported entry into male chastity play available, backed by decades of refinement and the most comprehensive spare parts and accessory ecosystem in the category.

CB-X Product Range

The CB-6000 is the original and most widely sold CB-X design. The cage is made from medical-grade polycarbonate in a straight tube profile with a rounded tip. Each CB-6000 includes five base rings in graduated diameters and four spacers in different lengths, allowing the wearer to find the ring-spacer combination that sits securely against the body without being too tight or too loose. The cage locks with a standard padlock or the included numbered plastic locks. The CB-6000 suits most first-time chastity device buyers and is the natural starting point in the range.

The CB-6000S is the short version of the CB-6000, with a shorter cage tube suited to anatomies that do not fill the standard-length cage comfortably. The same five-ring, four-spacer sizing system applies. The CB-6000S is recommended for buyers who find the standard cage allows too much movement of the penis inside the tube, which reduces the device's security and comfort during extended wear.

The CB-X Curve is a curved cage design that follows the natural downward hang angle of the flaccid penis more closely than the straight CB-6000 tube. This more anatomically aligned geometry makes the Curve noticeably more comfortable during extended wear, particularly during sitting and sleep, as the cage follows the body's natural resting position rather than holding the penis at a fixed angle that works against gravity. The Curve uses the same base ring sizing system as the CB-6000.

The Bon4 is a flexible medical-grade silicone chastity cage for buyers who want a softer, more skin-compatible alternative to the rigid polycarbonate cage formats. The silicone construction is more forgiving against the skin during long wear periods, less visible under clothing due to its flexibility and softer profile, and suited to buyers who have found hard plastic cage edges uncomfortable during movement. The Bon4 is available in standard and mini sizes.

CB-X spare parts and accessories cover individual replacement rings, spacers, locks, and pins for buyers who have lost or damaged components without needing to replace the full cage system. The spare parts ecosystem is one of the most complete in the chastity category and is a significant practical advantage of choosing CB-X over less established brands that do not support replacement parts.

CB-X sizing kits allow buyers to test ring sizes before purchasing a complete cage system, which is the most reliable way to find the correct base ring diameter for a secure and comfortable fit before committing to a device.

Who Buys CB-X Products

Buyers new to male chastity devices most commonly start with the CB-6000, which is the most widely recommended first chastity cage available due to its systematic sizing approach, comprehensive spare parts support, and decades of proven performance. The inclusion of multiple ring and spacer sizes in every CB-6000 purchase means the buyer has everything needed to find a correct fit without additional purchases.

Buyers who have found the straight CB-6000 profile uncomfortable during extended wear often move to the CB-X Curve, whose anatomically aligned geometry produces a meaningful improvement in comfort for wearers who sleep or sit for long periods while caged.

Buyers with a latex or hard material sensitivity, or who want a chastity device that sits less visibly under clothing, choose the Bon4 silicone cage for its softer construction and more forgiving wear profile.

Partners in dominant-submissive relationships who manage a caged partner's device often appreciate the CB-X spare parts range, which allows specific replacement components to be ordered individually when locks are changed, rings are resized, or parts are lost during longer-term chastity arrangements.

Choosing CB-X Products

Sizing is the most important factor in chastity device selection and should be treated as such. A base ring that is too large allows the cage to be removed entirely without the key, which defeats the purpose of the device. A ring that is too small restricts blood flow, causes swelling, and can be medically dangerous during an erection. CB-X provides multiple ring sizes with every device to allow systematic size testing. If you are buying your first chastity device, order a CB-X sizing kit before purchasing a full cage to test ring sizes without the additional investment of the complete device.

Choose the CB-6000 as your starting point unless you have a specific reason to start with another model. The CB-6000 is the most documented, most supported, and most widely tested chastity cage in the world, and the amount of user knowledge available about fitting and wearing it correctly is unmatched by any competing design.

Choose the CB-6000S if your flaccid penis length is shorter than average and you find the standard cage allows your penis to move significantly inside the tube. Movement inside the cage reduces security and increases chafing during extended wear.

Choose the Curve if you plan to wear the cage during sleep or for extended sitting periods. The curved profile follows the body's natural resting anatomy more closely and reduces the leverage and pressure that a straight cage can create against the base ring and perineum during prolonged wear in sedentary positions.

Choose the Bon4 if you want a softer cage for long-term wear comfort or reduced visibility under clothing. Be aware that silicone cages are generally considered slightly less secure than rigid polycarbonate cages in most wear scenarios.

Looking After CB-X Products

Clean CB-X polycarbonate cages with warm water and mild soap during daily hygiene routine. The cage should be cleaned thoroughly including inside the tube and around the base ring seating area. A soft brush or pipe cleaner assists with reaching inside the tube for thorough cleaning. Allow to dry completely before storage when the device is not being worn.

Inspect all locking pins, ring seating points, and cage body for any cracks or stress fractures before each use. Polycarbonate can crack if subjected to significant force or impact, and a cracked cage presents both a security and safety risk. Replace any cracked components immediately using CB-X spare parts.

Clean Bon4 silicone cages with warm water and mild soap and rinse thoroughly. Silicone can be sanitised more thoroughly than polycarbonate. Allow to dry completely before storage.

Keep spare numbered plastic locks on hand for hygienic lock rotation during extended chastity arrangements. Metal padlocks are more secure but require a key; numbered plastic locks allow visual confirmation of security without a physical key and are useful for training and supervised wear arrangements.

Goes Well With

CB-X spare parts and sizing accessories pair directly with all CB-X cage formats, allowing buyers to replace individual components rather than entire systems and to adjust sizing as the body changes during extended wear arrangements. A quality intimate cleanser is useful for daily cage hygiene during extended wear periods.
