Child sexual exploitation (CSE) is a type of child abuse. It happens when a young person is encouraged, or forced, to take part in sexual activity in exchange for something. The reward might be presents, money, alcohol, or simply just the promise of love and affection.
It might seem like a normal friendship or relationship at the beginning, but the young person might be persuaded to do sexual things they don't want to do in return for something.
If you have any concerns that something just isn't right then you should report it to 101.
