A statement of one's own limit and the action one may take to protect it.

Boundary
A limit a person sets around their body, time, information, relationships or participation. It identifies what they will or will not accept rather than granting control over another person.
Consent & relationships
In brief
A personal limit—not an opening bid.
Boundaries make personal limits visible, but they are not self-enforcing and do not replace consent to each activity. They can be firm, conditional or change over time. Nobody owes negotiation, justification or gradual erosion of a stated limit.
Current agreement to a specific interaction; staying within a boundary does not automatically establish consent.
Something a person would like, but which may not function as a firm limit.
A requirement intended to govern conduct; rules and mutual agreements should not be disguised as another person's boundary.
Kinds of boundary
Limits may concern touch, activities, language, privacy, recording, disclosure, time, money, substances, relationships or after-contact. Some are permanent; others depend on context.
A person can discover a boundary only when something happens. Lack of earlier wording does not create permission to continue once discomfort or withdrawal becomes apparent.
Communication and accessibility
Clear language helps, but people differ in speech, processing and conflict responses. Written notes, advance discussion, communication aids or agreed non-verbal signals may improve access.
The listener still has responsibility to notice uncertainty and check. The burden should not fall entirely on the more vulnerable participant to deliver a perfect statement.
Respect without bargaining
Repeatedly testing, mocking or seeking loopholes in a limit can become pressure. A respectful response accepts the boundary and decides whether the remaining options are mutually workable.
A boundary is not punishment. If relationships are incompatible, adults may leave or renegotiate shared arrangements without threatening bodily access.
Change and repair
The person who owns a boundary may revise it freely; others should not treat earlier flexibility as a precedent. Changes need the same freedom and capacity as any other consent decision.
If a boundary is crossed, stop, address safety and listen to impact. Whether the event is also a consent violation or offence depends on what occurred and the applicable law.
