Consensual sex means that everyone taking part has agreed to it and knows what is involved. A person must understand what it is that they are agreeing to, so if someone is under the influence of alcohol or drugs they are not able to give consent. Young people aged 12 years and under are not able to consent to sex, or sexual activity. Therefore, sex at this age is considered to be sexual assault.
If someone feels pressured or forced to have sex this doesn't mean that they have given their consent. Even if someone agrees to have sex they can change their mind and decide to stop at any point. For more information on sexual assault and consent please see Your Sexual Health Matters.
