In order to give consent, a person must have both the freedom and the capacity to make a choice. This means a person must not be pressured by external influences, or lacking the capacity to make a choice (for example, being drunk, drugged or unconscious).
Sexual activity without consent is a crime. In any sexual situation, it is important to know exactly what a person has said yes to and what a person has said no to. You must not take advantage of someone’s consent by pushing the boundaries beyond their comfort zone.
Consent must be freely given, and remember that consent can be withdrawn at any time.
