“Child sexual abuse is any interaction between a child and an adult (or another child) in which the child is used for the sexual stimulation of the perpetrator or an observer. Sexual abuse can include both touching and non-touching behaviors. Touching behaviors may involve touching of the vagina, penis, breasts or buttocks, oral-genital contact, or sexual intercourse. Non-touching behaviors can include voyeurism (trying to look at a child’s naked body), exhibitionism, or exposing the child to pornography.
Abusers often do not use physical force, but may use play, deception, threats, or other forms of coercion to engage children and maintain their silence. Abusers frequently employ persuasive and manipulative tactics to keep the child engaged. These tactics—referred to as “grooming”—may include buying gifts or arranging special activities, which can further confuse the victim.” – The National Child Traumatic Stress Network
