What could make a child this way ***TW***

Child age 7 had or*l sex with same age peer. Started acting out same behaviors on dolls. Then at 11 played humping game with same age cousin. Humped sister and pushed dogs face to privates clothed. Urges to sexually touch other people.

Was there any sort of s*xual abuse going on at the time? Or beforehand. In my experience children who are groomed and/or abused s*xually sometimes suffer with hypersexuality later on? If its not you, I'd recommend talking to them immediately, and if it is you, I feel you. I do. If you go to see a therapist please tell them your past experiences. I really hope you can get some help, love~ ❤
