Consent is agreement, permission, or willingness to have contact of a sexual nature.
Consenting is saying 'yes' without threats, coercion or emotional blackmail.
A person has the right to change their mind at any time during a sexual encounter. If someone says "no", "stop", "I'm not sure I want to do this" or through words or behaviour implies no, then you no longer have consent. You must stop. Pushing someone away, moving the other's hands, trying to get away, resisting or putting clothes back on are all signs of refusal.
