Kink, like any world, has its own language, and understanding it is key to navigating it with confidence. This glossary provides definitions, context, and insights into terms commonly used in BDSM and alternative relationship dynamics.
Relationship Dynamics
- Consensual Non-Monogamy (CNM): An umbrella term for relationships in which all partners agree to engage in multiple sexual or romantic relationships. This includes various forms such as polyamory, open relationships, and swinging.
- Ethical Non-Monogamy (ENM): Similar to CNM, this term emphasises the importance of honesty, transparency, and consent in engaging in multiple relationships.
- Polyamory: The practice of engaging in multiple romantic or intimate relationships simultaneously, with the knowledge and consent of all parties involved. The term combines Greek and Latin roots: ‘poly’ meaning ‘many’ and ‘amory’ meaning ‘love.’
- Polycule: A network of interconnected individuals in polyamorous relationships. The structure can vary widely, encompassing various relationship dynamics among its members.
- Metamour: A term used to describe your partner’s partner, with whom you do not share a direct romantic or sexual relationship. For example, if your partner has another partner, that person is your metamour.
- Compersion: The feeling of joy one experiences when their partner finds pleasure and fulfillment in another relationship. It’s often described as the opposite of jealousy in the context of polyamory.
- Hierarchical Polyamory: A structure in which relationships are ranked in terms of importance or priority. Typically, there is a ‘primary’ relationship that may hold more significance, with ‘secondary’ or ‘tertiary’ relationships considered of lesser priority.
- Non-Hierarchical Polyamory: A relationship structure where no single relationship is deemed more important than another. All relationships are considered equal, and there is no ranking system among partners.
- Polyfidelity: A form of polyamory where all members are equally committed to each other and agree not to engage in sexual or romantic relationships outside of the established group.
- Solo Polyamory: An approach where an individual engages in multiple relationships but maintains an independent lifestyle without seeking to merge lives, finances, or housing with partners. Autonomy and personal freedom are emphasised.
- Kitchen Table Polyamory: A style of polyamorous relationships where all partners and metamours are comfortable spending time together, akin to sitting around the kitchen table. This approach fosters a sense of community and openness among all involved.
- Parallel Polyamory: A form of polyamory where one’s partners prefer not to interact or engage with each other. Relationships run concurrently but separately, with minimal or no contact between metamours.
- New Relationship Energy (NRE): The excitement and emotional high experienced at the beginning of a new romantic relationship. In polyamorous contexts, managing NRE is important to maintain balance among multiple relationships.
- Vee (V) Relationship: A polyamorous relationship involving three people where one person (the ‘hinge’) is romantically involved with two others (the ‘arms’), who are not romantically involved with each other.
- Triad: A relationship involving three individuals who are all romantically or sexually involved with each other. Also known as a ‘throuple.’
- Quad: A relationship involving four individuals, which can form through two couples coming together or other configurations. The relationships among members can vary in terms of romantic and sexual involvement.
- Swinging: A form of non-monogamy where committed couples engage in sexual activities with others, typically in a recreational or social context. Emotional or romantic connections are generally not pursued.
- Open Relationship: A relationship in which partners agree that each may engage in sexual or romantic relationships with other people. The specifics can vary widely and are typically negotiated between partners.
- Monogamish: A term popularised by author Dan Savage, describing a relationship that is primarily monogamous but allows for occasional sexual experiences outside the partnership, under agreed-upon conditions.
- Relationship Anarchy: A philosophy that rejects traditional relationship hierarchies and labels, advocating for relationships based on individual autonomy, consent, and mutual agreement rather than societal norms.

After an inspection, a sub may be rewarded for passing or punished for failing. Inspections may also be performed for eroticism or objectification, either in private or in view of others.
