So my niece is 14. Rewind to age 7. Her and a boy also 7 engaged in oral sex. She began do this behavior with dolls. Age 11 she and a female cousin humped each other. Acting sexually with animals ( pressed dogs mouth to privates and humped sister. At age 11. now 14 and having sexual thoughts toward younger children. What could have possibly happened to her to make her like this? Alot of kids are sexually abused or sexualized and not like this. She remembers no abuse by an adult.
