In the UK, a boy or girl cannot legally consent to sex until they are 16.
However, just because you are 16 doesn't mean you consent.
Sex without consent is rape.
The onus of proving the sex was consensual is on the man accused of rape. He has to prove that he took steps to ensure you wanted to have sex with him. This means it is not up to you to have said no or to have tried to fight. Consent has to be actively sought.
Some people may not be able to give consent such as people with learning disabilties, this is because they don't understand the issues.
You may also be unable to consent due to being under the influence of drugs or alcohol.
Sexual intercourse with a child 13 years old and under is automatically rape whether the child believes they consented or not (Sexual Offences Act 2003). Legally children 13 years old and under cannot give consent to sexual intercourse. This is true regardless of what the perpetrator has told you, no matter what you said, what you did, how your body responded, if you were 13 years old or under this is automatically classified as rape.
