Saying that paedophiles often only speak to other offenders suggests that paedophilia is a crime. It could be better to make a distinction between people of certain sexual orientation and people who commit certain crimes, unless you believe that these two groups of people intersect completely.

I have not encountered any evidence that a certain treatment or social surrounds can change a person's sexual orientation, so avoiding unacceptable thoughts may be impossible for these people. Avoiding unacceptable behaviors is certainly achievable, though.
