Relationship structures
Polyfidelity
A relationship agreement limiting additional romantic or sexual involvement within a defined group.
Other names and related terms: Closed polyamory
Understanding the topic
Closure does not mean every member dates every other member. Entry, exit, and changing agreements must remain individual choices.
Relationship vocabulary describes approaches, connections, or expectations rather than a complete agreement. Two people using the same word may have different practical commitments. Time, privacy, exclusivity, housing, and support deserve concrete discussion.
A closed agreement needs clarity about which connections and activities are included and what happens when someone wants a different arrangement. It cannot make a member remain in a relationship they no longer want. Discuss disclosure and exit without threatening exclusion from essential support.
Do not assume that a group agreement settles consent for every possible encounter between members. Each relationship and each activity still involves particular people with their own boundaries.
Consent and communication
Make commitments directly with the people affected and explain relevant existing obligations honestly. Nobody can promise another adult’s participation or distribute their private information. People can decline a structure without being judged immature.
A practical example
A group discusses its boundaries and accepts a member choosing to leave.
Common misunderstandings
A relationship label does not guarantee compatible values or identical priorities. It is not a moral ranking of relationship styles, and it cannot settle permission for specific sexual or kink activities.
Safety and risk awareness
Watch for promises that exceed actual availability or conditions disclosed only after involvement begins. Unequal resources and social pressure can affect a person’s ability to refuse. Discuss these effects rather than only intentions.
