Not technically, no. Pedophilia is a sexual attraction to prepubescents. Teens aren't prepubescent, outside of those with medical disorders.
Even if they were married, I would still call sex with them satutory rape though. And since they haven't reached the age of consent, I wouldn't think they could legally sign a marriage contract either. So I have no idea how any of this is even really possible as the law currently stands.
I get that. But being their parent, and having the impulse to protect or defend them, doesn't mean it's the right thing to do.
