Consent takes place when someone agrees, gives permission, or says “yes” to sexual activity with another person or persons. Consent is always freely given and all people in a sexual situation must feel that they are able to say “yes”, or “no”, or stop the sexual activity at any point. Consent can be withdrawn by either party at any point. Consent to engage in one sexual activity, or past agreement to engage in a particular sexual activity, cannot be presumed to constitute consent to engage in a different sexual activity or to engage again in a sexual activity. Consent cannot be validly given by a person who is incapacitated, which includes intoxication or any other hindrance to clear communication.
