Consent

Within BDSM, consent is the explicit and informed agreement by a participant to engage in specific acts or types of relationships.[1]

Consent occurs when one person voluntarily agrees to the proposal or desires of another.[2] Within BDSM it bears much in common with informed consent.[1] It is also a personal, ethical and social issue at the same time.[1]

Where an act has been previously consented to, the consent can be terminated at any point, and by any participant, through using a safeword.[3] Consent can also be revoked at any moment.[4] Within the BDSM community, it is generally considered a high risk activity to engage in BDSM without a safeword.[5]

One study has shown that BDSM negotiations to establish consent consist of four parts covering style of play, body parts, limits and safewords.[6] The issue attracts much attention within BDSM, resulting in competing models of consent.[1] Safe, sane and consensual is the most recognisable and popular of these, though not without criticism.[7] Risk-aware consensual kink was created to overcome perceived shortcomings of SSC.[8]

To obtain affirmative consent, one gives and seeks an explicit yes, which can come as a smile, a nod or a verbal yes, as long as it is unambiguous, enthusiastic and ongoing.[9] Even so, affirmative consent may still be limited, since the underlying individual circumstances cannot always be acknowledged in a yes-means-yes or no-means-no model.[10]

Consent is not a single yes. It is revisited before, during and after every scene.
