What is consent? Consent is a voluntary agreement that exists between sober, non-coercive, mentally capable adults when they engage in activities together. Consent is given or withdrawn at any time. Just because a person has had consent in the past does not mean they will have it in the future. This is a very important concept and requirement that must be established within any sexual relationship. It is absolutely crucial to understand that if your partner does not expressly give his consent and does not commit a sexual act on him, it means that you have been sexually assaulted
