There's some good information in that article. TY for posting it.
I take issue with portions of the etiology section that makes the claim about the cause of pedophilia (blaming childhood sexual abuse), but doesn't cite a peer-reviewed publication to support the claim.
To my knowledge, there is no conclusive scientific evidence that explains a clear etiology of pedophilia. While there may be some hypotheses which suggest a correlation involving some victims of childhood sexual abuse and pedophilia, there is, IMO, no proof of causation.
Many children are molested but do not (when they reach adulthood) become pedophiles.
