Dynamic consent is a model of consent practiced by some people within the BDSM community, in which consent is seen as fluid and changeable at any time.
Dynamic consent is the opposite to blanket consent or contract consent, which are two models of consent where consent does not change once it’s been granted. In fact, this model of consent has been embraced by members of the BDSM community who feel contract and blanket consent models can fall short in creating an atmosphere of truly consensual sexual activity.
