Child sexual abuse is when an adult (or sometimes another older person or even another child) uses you for their own sexual pleasure. This can mean they touch you in private places like your chest or genitals, or it could mean they make you touch them in private places. It could also involve talking about sex with you in a way that is not appropriate, or looking at private parts of your body. No matter who it is, no one should be touching you in any private places and making you feel uncomfortable in any way.
