Clear language, organized by category.

Negotiated adult relationship dynamics in which one partner's outside erotic or romantic experiences are discussed, encouraged, or enjoyed by the couple, often with an emphasis on compersion, jealousy management, and explicit consent.

A consensual fantasy or negotiated dynamic in which one partner eroticizes their other partner having sexual or romantic experiences with someone else, sometimes with jealousy, humiliation, reassurance, or compersion themes.

A negotiated kink or erotic connection between consenting adults that focuses on play, intimacy, or exploration without needing a romantic partnership or long-term relationship structure.

Dedicated, consent-based kink environments—such as a dungeon, club, studio, or private scene space—set up with equipment, rules, and oversight so adults can negotiate and enact BDSM or fetish activities more safely and predictably.

The pre-scene conversation where consenting adults agree on what they do and do not want, how far things may go, what safety and privacy rules apply, and how they’ll check in and care for each other afterward.

Agreed words, gestures, or objects used by consenting adults to pause, adjust, or immediately stop an activity.

Trained event volunteers or staff who help keep kink spaces safer by watching for rule violations, checking consent, and responding to concerns or emergencies.

A hinge relationship is a consensual non-monogamous structure where one person is the shared partner in a V-shaped network: they date two people who are not dating each other. The shared person is the "hinge," and the two partners are often called metamours.

A consensual non-monogamous arrangement where a defined group of adults agrees that partner-swapping or shared sexual play stays within that group, rather than including outsiders.

An agreed arrangement where consenting adults play in separate spaces—such as different rooms, behind a closed door, or with swapped partners—rather than all being physically together.

Simultaneous penetration of one consenting adult by two body parts, toys, or a combination, with the exact anatomy and configuration explicitly discussed.

A consensual group-sex encounter in which one consenting adult engages with multiple other consenting adults, either sequentially or with overlapping interaction, according to pre-negotiated boundaries.

Figging is a sensation-play practice where peeled ginger is placed against genital or anal tissue to create a sharp warming, burning, or stinging feeling. It is edge play because it can easily irritate or injure delicate mucosa.

A negotiated impact-play practice focused on the soles of the feet, used by consenting adults and treated as an advanced-risk activity because the feet are important for balance, standing, and walking.

A full-body, highly slippery massage style that uses a purpose-made gel to encourage extensive skin-to-skin contact between consenting adults.

Controlled friction or rough texture applied to the skin to heighten sensation in a negotiated, consent-based way between consenting adults.

Negotiated, control-themed play in which consenting adults play with requests, permission, timing, or rituals around restroom access, without delaying necessary bodily care.

Cock and ball play (CBT) is negotiated genital sensation play focused on the penis and/or testicles. It can include pressure, restraint, teasing, or impact, but it sits in an edge-risk category because the area is highly vulnerable to bruising, swelling, nerve injury, torsion, and other acute harm.

An agreed format in which consenting adults remain in the same room while separate pairings, swapped partners, or a group engage in sexual or kink activity.
