BDSM Glossary: Key Terms Explained

Aftercare — The period following an intense BDSM scene in which both dominant and submissive decompress, reconnect, and address any physical or emotional needs. Aftercare is considered essential for both parties, not optional.

BDSM — An umbrella acronym covering Bondage/Discipline, Dominance/Submission, and Sadism/Masochism. It encompasses a wide range of consensual adult activities centred on power exchange, sensation, and role dynamics.

Bondage — The practice of restraining a person using rope, cuffs, chains, tape, or other means. Bondage ranges from symbolic (wrist ties) to elaborate (full body shibari) and is one of the most common BDSM activities.

Bottom — The partner receiving sensation, instruction, or control in a scene. Bottoms are not necessarily submissive — some identify as bottoms without a power-exchange dynamic.

CBT (Cock and Ball Torture) — A category of male-specific sensation play involving the genitals. Techniques range from light bondage and teasing to more intense sensation. Performed by experienced providers only.

Chastity — A form of control in which the dominant controls the submissive's access to sexual release, often using a chastity device. Can be short-term (within a session) or long-term (ongoing with a provider).

Collar — In BDSM relationships, a collar may be worn by a submissive as a symbol of their relationship to a dominant. In professional sessions, some providers use collars as part of session protocols.

Consent — The cornerstone of all BDSM practice. All activity must be explicitly agreed to in advance by all parties, with the ability to withdraw consent at any time.

CNC (Consensual Non-Consent) — A type of roleplay in which parties have pre-negotiated a scenario that appears non-consensual but is fully agreed upon in advance. Requires very clear negotiation and established trust.

D/s — Abbreviation for Dominance/submission — the power-exchange dynamic at the core of many BDSM relationships and sessions.

Discipline — The use of rules, structure, and consequences (including punishment) to maintain control within a D/s dynamic. Discipline focuses on behaviour and correction.

Dom/Domme — Dom is typically used for a male dominant; Domme (or Dominatrix) for a female dominant. A dominant is the person who holds and exercises control in the dynamic.

Drop — See Sub Drop.

Dungeon — A dedicated space equipped for BDSM sessions, containing furniture (crosses, benches, suspension points), implements, and safety equipment. Professional dungeons are operated by experienced practitioners.

Edgeplay — BDSM activities that carry elevated risk and require significant experience and care. Examples include breath play, fire play, and extreme bondage positions. Not offered by all providers.

Femdom — Female Domination — sessions or dynamics in which a female dominant exercises control over a submissive, regardless of the submissive's gender. One of the most common professional BDSM session types.

Financial Domination (FinDom) — A power dynamic in which control is expressed through financial tribute, gifts, or monetary submission. Can be practiced in-person or online.

Flogger — A multi-tailed impact implement. Floggers vary enormously in weight and sensation — from lightweight suede that creates a thudding warmth, to heavy leather that delivers sharp, stinging impact.

Foot Worship — A form of submissive service in which the submissive pays devotional attention to the dominant's feet, including kissing, massaging, and worshipping them within an agreed protocol.

Hard Limit — An activity that a person will not do under any circumstances, regardless of negotiation. Hard limits must be fully respected by all parties.

Headspace — The mental or emotional state a person enters during an intense BDSM scene. For submissives, this is often called subspace; for dominants, domspace.

Humiliation — A psychological form of power exchange involving verbal degradation, embarrassment, or demeaning actions agreed upon in advance. A specific speciality of many professional dominatrices.

Impact Play — BDSM activity involving controlled striking of the body using hands, implements (floggers, canes, paddles, crops), or other tools. Ranges from light spanking to intense corporal sessions.

Kink — A general term for sexual or erotic interests that fall outside mainstream norms, including BDSM, fetish, and power exchange.

Masochism — Deriving pleasure from the experience of pain or intense sensation. In professional sessions, a masochist seeks out sensation as part of power exchange, stress relief, or for the endorphin/subspace experience.

Mistress — A common title used to address a professional dominatrix, particularly in the UK. Equivalent to "Mistress" or "Lady" in various cultural contexts.

Munch — A casual, non-play social gathering for people in the BDSM community. Munches are typically held in public venues and allow community members to meet in a non-sexual context.

Negotiation — The process of discussing and agreeing on all activities, limits, and safety protocols before a scene begins. Essential for every session, regardless of experience level.

NRE (New Relationship Energy) — The intense, sometimes irrational feelings that accompany a new dynamic or relationship. In professional contexts, new clients should be aware of NRE when assessing how they feel about a provider.

Pegging — Strap-on penetration of a submissive by a dominant. A common professional BDSM service offered by many dominatrices.

Play — In BDSM, "play" refers to consensual BDSM activity. A session or scene may be described as play; participants may be referred to as "play partners."

Power Exchange — The consensual transfer of control from one person (the submissive) to another (the dominant). Power exchange is the core dynamic of D/s and forms the basis of most professional BDSM sessions.

Protocol — Specific rules, rituals, or behaviours required within a D/s dynamic. Protocols may govern how a submissive addresses a dominant, positions required during a session, or other behavioural expectations.

Sadism — Deriving pleasure from the consensual administration of pain or intense sensation. A sadistic dominatrix enjoys the craft of sensation play and derives genuine satisfaction from well-executed scenes.

Safe, Sane, and Consensual (SSC) — A foundational BDSM safety philosophy. All activities should be safe (managed to minimise risk), sane (conducted by parties who understand what they are doing), and fully consensual.

Safe Word — A pre-agreed word or signal that immediately stops all activity. Most commonly, a colour system is used (red to stop completely, yellow to slow down or check in). Safe words are always respected.

Scene — A single BDSM session or encounter. "Playing a scene" means conducting a BDSM session.

Screening — The process by which professional providers verify a new client's identity and assess their suitability. Screening typically involves providing ID, social profiles, or work references.

Sissy Training — A form of feminisation play in which a male submissive is trained, dressed, and instructed in stereotypically feminine behaviours. May include crossdressing, makeup instruction, and behaviour modification.

Soft Limit — An activity a person is hesitant about or has limited experience with, but may be willing to explore under the right conditions with a trusted partner.

Subspace — The altered mental state experienced by some submissives during intense BDSM activity. Described as floaty, dissociative, or deeply calm — the result of endorphin release and psychological surrender.

Sub Drop — A crash in mood and energy experienced by some submissives after an intense scene, as endorphin levels return to normal. Proper aftercare helps manage sub drop.

Top — The partner giving sensation, instruction, or control in a scene. Tops are not necessarily dominant — some identify as tops without a power-exchange dynamic.

TPE (Total Power Exchange) — An arrangement in which the submissive surrenders a very high level of control to the dominant across multiple areas of life. More common in ongoing relationships than professional sessions.

Tribute — A payment or gift given to a dominant as a mark of respect or submission. In professional contexts, the tribute is the session fee. In FinDom, tributes are the central dynamic.

Vanilla — Non-kink. "Vanilla sex" or "vanilla relationship" refers to conventional, mainstream sexual or romantic activities without BDSM or power exchange.

Wax Play — A form of sensation play using hot candle wax dripped onto the skin. Produces brief heat, a spreading warmth, and the tightening sensation of cooling wax — a popular and visually striking form of BDSM sensation.
