I think you’re misunderstanding the definition of what that word means.
1) A 12/13 year old and a 16 year old experimenting is likely pedophilia depending on the biology of the 12/13 year old.
2) consent is a circular argument. The assumption that they can’t give consent arises from the assumption of harm and therefore cannot be used to justify harm.
Animals for example can’t give consent to each other, that doesn’t make two bald eagles reproducing harmful.
