Consent is probably the most important word in the BDSM world. Consent describe the agreement of all sides to everything that happens during a scene, which is a mandatory condition for any BDSM encounter. A scene must always be consensual and have clear boundaries. In order to provide a safe environment for BDSM participants, a safeword is often agreed upon prior to a scene. In some cases, partners may write down what activities they are willing to participate in, in what’s sometimes known as a BDSM contract.
