Sexting is when you send a sexual message, photo or video to someone else.
It could be a picture of you, but sometimes people send pictures and videos of other people.
Messages could be to a friend, boyfriend, girlfriend or someone online.
Sexting includes: being partly or completely naked, or in your underwear posing in a sexual position, sending ‘nudes’ or ‘dick pics’, talking about sexual things you’re doing or want to do, doing sexual things on a live stream
