I'll say it one more time:

A pubescent minor masturbating in their own privacy is not pedophilia. Them using sex toys in their own privacy would not be pedophilia either. It's just a little unusual. A pedophile is someone who is sexually drawn to children. Pedophilia is the sexual exploitation of a child by an adult. You keep asking how the above scenario isn't pedophilia and I'm explaining to you that nothing is pedophilia unless an adult is sexually abusing a child. A child exploring themselves in their own privacy with the aid of a tool is not pedophilia. Is it not a common thing? Yes. Is it pedophilia? No. You're not bright.
