What is pedophillia?

Pedophilia is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive sexual attraction to prepubescent children. Although girls usually begin puberty at ages 10 to 14 and boys at ages 12 to 16, the age at which puberty starts varies significantly from person to person, and definitions of prepubescence vary somewhat but generally refer to children aged before 13. Pedophilia may involve sexual thoughts towards or sexual acts with a prepubescent child
