This is a common reaction to premature sexual exposure or a traumatic sexual experience. If a child is too young to be excessively masturbating or is engaging in pre-mature sexual play or behavior, this is typically a sign that the child has witnessed, been a participant in or has been exposed to adult sexuality. In adolescence and adulthood, this can take the form of promiscuity, illegal sexual activity such as prostitution or participation in pornography, escort services, etc.
