Consensual sexual activity requires an ongoing, affirmative Consent, for the act in which the participants are involved. More specifically, affirmative Consent means an expressed, affirmative, conscious, and voluntary agreement to engage in sexual activity. It is the responsibility of each person involved in the sexual activity to ensure that he or she has the affirmative Consent of the other, or others, to engage the sexual activity. Lack of protest, or resistance, or silence does not mean Consent. There is no Consent when there is force, expressed or implied, or when coercion, intimidation, threats, or duress is used to obtain Consent. Affirmative Consent must be ongoing throughout a sexual activity, and can be revoked at any time. The existence of a dating relationship between the persons involved, or the fact of past sexual relations between them, should never, by itself, be assumed to be an indicator of Consent. If a person is mentally or physically incapacitated or impaired so that such person cannot understand the fact, nature, or extent of the sexual situation, there is no Consent; this includes impairment or incapacitation due to alcohol or drug consumption, or being asleep or unconscious.
