Age Of Consent
In the UK, you can legally consent to sex from the age of 16. The law is there to protect you from abuse rather than to get you into trouble.
Sex under the age of 14 is always abuse in the eyes of the law, even if both participants are the same age. You won’t get in trouble for this if you are under 14 but you will get help. It’s also illegal for someone in a position of power like a teacher or doctor to have sex with someone under 18. It’s against the law for someone to sell or even show pornography to a person under 18 and the same goes for sex toys.
However, if you are 14 and over, you can access advice, sexual health screenings and contraception without telling your parents or guardian. The professional you see will just have to make sure you understand everything and that you aren’t being abused or exploited.
