Chastity Cage

A chastity cage is a device worn over the penis to prevent erections, masturbation, or sexual access. It is the cornerstone of male chastity play and comes in a range of materials and styles, from lightweight resin to solid steel. Cages are used for discipline, denial, and control, whether worn solo or as part of a power exchange dynamic with a keyholder.

Nub Chastity

Cobra Cage

The Cobra Cage is a lightweight chastity device made from durable resin with a contoured, mesh-like design. It is popular for travel, beginners, and long-term wear thanks to its comfort and discreet profile.

Flat Chastity Cage

A flat chastity cage is designed to keep the penis completely flush against the body, with little to no protrusion. These cages are typically used by advanced wearers or those with smaller anatomy. They are ideal for stealth wear and often used in sissy or feminization play to minimise the appearance of male genitalia.

Small Chastity Cage

A category of chastity devices characterised by their minimal length, designed to house the penis in a significantly shrunken, retracted state. Short cages are popular in long-term chastity dynamics for their discretion and comfort under clothing. They are also frequently used in sissification and small-cock humiliation play, where the small size visually emphasises the wearer’s surrender, sometimes tied to terms like "chastity clitty."

Cock and Ball Cage

A cock and ball cage is a device that restrains both the penis and the testicles. It is more restrictive than a standard cage and often used in bondage, discipline, or advanced denial play. It can create noticeable pressure during arousal, reinforcing control and submission.

Related: Cock Restraint, Cock Bondage.

Cock Restraint

An umbrella term for any method or device that limits the penis’s ability to move, gain a full erection, or be stimulated. Cock restraint devices include chastity cages, cock rings, straps, and certain urethral inserts. Used heavily in chastity play and BDSM, the purpose is to enforce orgasm denial and reinforce power exchange. As with any restraint device, correct sizing of the base ring and cage is essential for safety and comfort, so measure carefully before you buy.

Cock Ring

A cock ring is worn around the base of the penis to maintain erections or delay ejaculation. While not a chastity device on its own, it is often used alongside cages for aesthetic or functional enhancement, and the base ring of a cage performs a similar anchoring role.

Biometric Locking

Biometric locking refers to chastity devices that use fingerprint scanners or app-based authentication to unlock. These high-tech cages add a layer of digital control, letting remote keyholders manage access securely. It is popular in long-distance dynamics and tech-savvy kink setups.

Chastity Anal Plug

A chastity anal plug is a butt plug either built into or worn alongside a chastity cage. It adds physical stimulation, fullness, or control to the experience. Often used in femdom, sissy play, or full-body restraint scenes, it reinforces submission and heightens the sensation of being locked.

Electric Cock Chastity

This refers to chastity devices equipped with electrostimulation (e-stim) features. These cages can deliver controlled electric pulses to the penis for punishment, teasing, or sensory play. They are typically used in advanced BDSM scenes and require careful, informed use to stay safe.

Related: Vibrating Chastity Cage.

Vibrating Chastity Cage

A vibrating chastity cage includes built-in or attachable vibration, often controlled via Bluetooth or a remote app. These cages are used for teasing, punishment, or sensory overload while the wearer stays locked, letting keyholders stimulate or frustrate a submissive without granting release. They are popular in long-distance and tech-enhanced dynamics.

Urethral Chastity Cage

A urethral chastity cage includes a urethral insert, a tube that sits inside the penis while the cage is worn. This design adds an extra layer of control and restriction, often used in advanced chastity or medical kink play. Urethral cages demand strict hygiene and experience, as improper use can cause injury or infection, so they are best approached by seasoned wearers.

Travel Cage

A travel cage is a chastity device designed for discreet wear on the move. Typically made from non-metal materials like medical-grade resin, durable plastic, or silicone, these cages are lightweight and will not trigger airport metal detectors. Travel cages prioritise comfort, stealth, and hygiene, making them ideal for long-term wearers who want to stay locked while travelling.

Penis Lock

A penis lock refers to any device that restricts access to the penis, including chastity cages, belts, or plugs. It symbolises control, denial, and submission. Some penis locks are decorative, while others are highly secure and used in long-term chastity or BDSM play.

Related: Chastity Cage, Chastity Belt.

Hygiene and Sizing

Essential practical considerations for anyone wearing a chastity cage. Sizing means accurately measuring your base ring diameter and cage length to ensure comfort, prevent injury, and guarantee security. Hygiene covers the daily cleaning routine that prevents skin irritation, odour, and infection during long-term wear.

See our measuring guide, ring size guide, and cage cleaning guide.

Chastity Belt

A locking garment, often made of metal or rigid materials, designed to cover and restrict access to the genitals. Historically the chastity belt was said to enforce fidelity, though much of that history is mythologised. In modern kink, belts are used consensually as a form of sexual restriction and power exchange, symbolising the wearer’s surrender of sexual agency to a keyholder.

Cock Bondage

A broad term for the bondage techniques, restraints, and devices (including chastity cages and cock rings) used to restrict or manipulate the penis and testicles. It is used to create heightened sensation, enforce denial, or visually emphasise sexual power dynamics.

Psychological Play & Erotic Rituals

Chastity Play

A consensual kink practice centred on orgasm denial and the physical or psychological restraint of sexual access, typically enforced through a chastity cage or belt. Chastity play is a form of power exchange in which the wearer surrenders control over their sexual release to a keyholder, often for extended periods. It creates sexual tension, heightened anticipation, and reinforces the dominant/submissive roles within the dynamic.

Related: Orgasm Denial, Femdom, Long-term Chastity.

Orgasm Challenge

An orgasm challenge is a structured game or ritual where the submissive must earn the right to orgasm through tasks, obedience, or endurance. Challenges may be set by a keyholder or self-imposed, and often include teasing, edging, or denial. They are used to reinforce discipline and deepen the psychological impact of chastity.

Related: Orgasm Denial, Locktober.

Orgasm Denial

Orgasm denial, also known as tease and denial, is the practice of preventing climax through physical restraint (like a chastity cage) or psychological control. It is a core element of chastity play, used to heighten arousal, reinforce submission, or build erotic tension. Denial may be temporary, prolonged, or indefinite depending on the dynamic.

Related: Ruined Orgasm, Enforced Chastity.

Ruined Orgasm

A ruined orgasm occurs when climax is allowed but intentionally manipulated to be incomplete, frustrating, or unsatisfying, often while the wearer is locked in a chastity cage. It sits between full release and total denial, and is a common tool for keyholders who want to grant relief without true satisfaction.

Related: Orgasm Denial, Edging.

Edging

Edging is the practice of bringing the body close to orgasm and then stopping, repeatedly, to prolong arousal without release. In chastity it is often used during supervised unlocking or tease sessions to intensify frustration and reinforce a keyholder’s control before the cage goes back on.

Related: Orgasm Denial, Ruined Orgasm.

Enforced Chastity

Enforced chastity is a consensual dynamic where the submissive is kept locked longer than they might choose on their own. The keyholder may deny release, ignore pleas for unlocking, or impose strict rules around removal. It adds a psychological edge to chastity play, emphasising control and power exchange.

Related: Forced Chastity, Keyholder.

Forced Chastity

Forced chastity describes the state of being locked into a cage by a keyholder and surrendering control over one’s sexuality to the dominant. While "forced" implies a lack of choice, it is rooted in mutual agreement and trust. The dominant may impose strict rules, extend lockup beyond the submissive’s comfort zone, or deny release entirely, making the experience both physically restrictive and emotionally intense.

Related: Enforced Chastity, Forced Chastity.

Chastity Humiliation

Chastity humiliation involves teasing, mocking, or exposing the submissive’s locked status. It may include verbal taunts, playful degradation, or rituals that highlight their lack of control. This kink blends erotic denial with psychological play, and often appears in cuckold, sissy, or FLR dynamics.

Related: Cuckold Chastity, Chastity Sissy.

The Wall

The "wall" refers to the intense mental barrier or breaking point many submissives experience during extended orgasm denial or forced chastity. Pushing through it often leads to the chastity mindset: the psychological shift where the wearer accepts their restricted status and finds peace, focus, or pleasure in surrendering sexual control to the keyholder.

Related: Mindful Chastity, Long-term Chastity.

Mindful Chastity

Mindful chastity is a solo or partnered practice where chastity becomes a tool for focus, self-awareness, or emotional regulation. It may include journaling, meditation, or rituals that deepen the psychological experience of denial. Mindful chastity emphasises intentionality and personal growth over purely erotic goals.

Related: Self-Chastity, The Wall.

Self-Chastity

Self-chastity is the practice of wearing a chastity cage without a keyholder. It is often used for personal discipline, erotic frustration, or mindfulness. The wearer sets their own rules, such as timed lockups, journaling rituals, or abstinence goals. Some use app-controlled cages to simulate external control, while others rely on willpower alone.

Related: Mindful Chastity, Digital Keyholding.

Long-term Chastity

The practice of wearing a chastity cage for extended periods, from several months to years, sometimes indefinitely. Long-term chastity shifts the dynamic from temporary play to a lifestyle, emphasising mental control, dedication, and integrating the device into daily life. Comfort, fit, and hygiene matter more than ever at this level.

Related: Hygiene and Sizing, Travel Cage.

Read Lockd’s guide to the best cages for long-term wear.

Negative Chastity

Negative chastity refers to cage designs that push the penis inward toward the body rather than simply enclosing it. These cages eliminate any visible protrusion and are popular in feminization, sissy play, and humiliation dynamics. They intensify the psychological aspect of chastity by visually erasing the male anatomy.

Related: Flat Chastity Cage, Chastity Sissy.

Chastity Erection

An uncomfortable or frustrating erection that occurs while the wearer is secured inside a chastity cage. Because the device limits the space available, the penis cannot achieve full rigidity, heightening the psychological tension and the sensation of restraint. Frequent chastity erections in the early days are normal and usually settle as the body adapts.

Related: Cock Restraint, Chastity Play.

Abstinence vs Chastity

Abstinence is the voluntary choice to refrain from sexual activity, often for personal, religious, or health reasons, with no physical barrier or external control involved. Chastity, by contrast, typically involves a physical device or a dominant partner enforcing denial. Chastity is usually part of a kink or power-exchange dynamic where control and restraint are central.

Related: Male Chastity, Self-Chastity.

Kink / Kinky

A broad term for non-conventional, fantasy-driven sexual preferences and practices that extend beyond "vanilla" activity. Kink is an umbrella covering BDSM (bondage, discipline, sadism, masochism), fetishes, role-play, and structured power dynamics like chastity and orgasm denial. Kink communities emphasise consent, often under Safe, Sane and Consensual (SSC) or Risk-Aware Consensual Kink (RACK) frameworks, and clear communication between all partners.

Related: Chastity Play, Penis Fetish.

Prostate Milking Chastity

Prostate milking chastity involves stimulating the prostate while the wearer stays locked in a cage. This can produce fluid release without a full orgasm, and is used in medical kink, denial play, or as a form of controlled release that does not "break" chastity.

Related: Chastity Anal Plug, Orgasm Denial.

Panties Chastity

Panties chastity involves wearing feminine underwear while locked in a chastity cage. It is common in sissy play, feminization, and humiliation dynamics. The combination of soft, feminine fabric and physical restraint reinforces role reversal and psychological submission.

Related: Chastity Sissy, Sissification.

Pegged in Chastity

"Pegged in chastity" describes a dynamic where a submissive is locked in a cage while being anally penetrated by a partner using a strap-on. This kink blends physical restraint with role reversal, often used in femdom, FLR, or sissy play to reinforce dominance and submission.

Related: Chastity Anal Plug, Femdom.

Penis Fetish

A penis fetish is an erotic focus on the penis, which may include admiration, control, denial, or transformation. In chastity play the fetish often shifts toward not touching or stimulating the penis, creating a paradox of desire and restraint. It appears frequently in humiliation, sissy, and medical kink scenes.

Roles, Relationships & Power Exchange

Dominant

In BDSM and chastity dynamics, the dominant (Dom or Domme) is the person who takes control. They may set rules, enforce discipline, and manage the submissive’s access to pleasure. In chastity the dominant often acts as the keyholder, deciding when, or if, the submissive is allowed release.

Related: Submissive, Keyholder, Femdom.

Submissive

A submissive is a person who consensually gives up control to a dominant partner. In chastity play the submissive may wear a cage to reinforce obedience, devotion, and erotic restraint. Submission can be physical, emotional, or psychological, and often involves rituals, rules, and negotiated boundaries.

Related: Dominant, Slave Contract.

Keyholder

A keyholder is the person who controls access to the chastity cage. They may be a romantic partner, friend, or professional dominatrix. Keyholders enforce rules, grant or deny release, and often play a dominant role in the wearer’s sexual life. Remote keyholding via apps is increasingly common.

Dominatrix Keyholder

A dominatrix keyholder is a professional or lifestyle female dominant who controls a submissive’s chastity. She may offer structured denial, punishment, and reward systems, often incorporating humiliation, tasks, and rituals. Some dominatrixes provide paid keyholding services, including digital control and regular check-ins.

Femdom

Femdom (female domination) focuses on erotic control and power exchange led by a woman. The dynamic typically involves tease and denial, humiliation, and chastity play. It can exist within an FLR, but a couple can also practise femdom in the bedroom without the woman leading the entire household.

Related: Female-Led Relationship (FLR), Chastity Mistress.

Chastity Mistress

A chastity mistress is a dominant woman who oversees a submissive’s chastity. She may set rules, enforce denial, and use the cage as a tool of control. "Mistress" implies a more holistic relationship of ownership and training, often extending control of chastity play into the submissive’s wider lifestyle, wardrobe, or finances.

Related: Keyholder, Femdom.

Female-Led Relationship (FLR)

In a female-led relationship, the woman takes the lead in major decisions, whether financial, social, familial, or sexual. Chastity, when included, is one component that reinforces her overall authority in the partnership. FLRs range from bedroom-only dynamics to full lifestyle arrangements.

Related: Femdom, Chastity Mistress.

Slave Contract

A slave contract is a formal agreement between a dominant and submissive that outlines expectations, limits, and responsibilities. In chastity dynamics it may cover lockup duration, orgasm denial, punishment protocols, and behavioural standards. While not legally binding, it serves as a framework for trust, consent, and structure, and is often revisited and updated as the dynamic evolves.

Related: Dominant, Submissive.

Sissymaker / Sissification

A cross-dressing and feminization kink dynamic where a submissive is trained, encouraged, or playfully "forced" to adopt a feminine persona. It often involves behavioural changes, feminine clothing and makeup, and a submissive sexual role. The chastity cage is a symbolic tool in sissification, limiting access to masculinity and reinforcing the role of a chastity sissy, often using a flat cage or "clitty." The dominant guiding this process is sometimes called a sissymaker.

Explore flat cages and pink chastity cages often used in sissy play.

Chastity Clitty

"Clitty" is a feminised term for the penis, used in sissy or feminization play. When a submissive is locked, the penis may be called a clitty to reinforce gender transformation, humiliation, or role reversal. It is a psychological tool as much as a linguistic one.

Related: Chastity Sissy, Sissification.

Chastity Sissy

A chastity sissy is a submissive who embraces exaggerated femininity while locked in chastity. This may include wearing panties, makeup, or adopting a feminised persona. The cage reinforces the submissive role and prevents masculine sexual expression, deepening the sissification experience.

Related: Sissification, Panties Chastity, Chastity Clitty.

Digital Keyholding

Digital keyholding uses apps or online platforms to manage chastity devices remotely. Instead of physically handing over a key, the cage is controlled via Bluetooth or the cloud. It is especially popular in long-distance dynamics, where a partner can lock or unlock the device from anywhere, often with timed release, emergency unlocks, and activity logs.
