Pedophilia is a paraphilia that involves an abnormal interest in children. A paraphilia is a disorder that is characterized by recurrent intense sexual urges and sexually arousing fantasies generally involving: nonhuman objects; the suffering or humiliation of oneself or one's partner (not merely simulated); or animals, children, or other nonconsenting persons. Pedophilia is also a psychosexual disorder in which the fantasy or actual act of engaging in sexual activity with prepubertal children is the preferred or exclusive means of achieving sexual excitement and gratification. It may be directed toward children of the same sex or children of the other sex. Some pedophiles are attracted to both boys and girls. Some are attracted only to children, while others are attracted to adults as well as to children.
