What's the medical definition of child molestation?

Child molestation. It is against the law for an adult to touch any portion of a child's body with a "lewd and lascivious" intent. Child molestation is a crime involving a range of indecent or sexual activities between an adult and a child (usually under 14 yrs old). Consent is not a matter of consideration in this matter since children cannot legally consent to anything.
Medical definition. I don't think there is a medical definition, this is likely a legal term that defines it for purposes of the law, age of consent is an issue, but sexual activity between an adult and a child meets my definition and i would report it to authorities.
