Let's use some logic here, OP:
You cannot be the first pedo that has noticed her. She'll be taken away either by you, or by another pedo who may or may not be a bad guy.
I think you actually love girls and sex doesn't seem to be your primary objective, so you have to do it. You have to, for her sake and for your spiritual fulfilment.
And if things become sexual, fine (as long as she consents), but her well being comes first. You may save her from rape.
In any case post results.
