Child porn and statutory rape are two separate things.

If this was filmed or broadcast and the age of majority is 18 with regard to pornographic depiction ? filming or broadcasting sex with an under age person is child pornography (a felony criminal offense).

If this was a person having sex, in private, with a person 17 years old ? the 17 year old is able to consent in most places voluntarily.

Being raped is a forced act (a felony criminal offense).
