if you masturbate to pedophillic stimuli for long enough then you will turn into a pedophile, a psychologist of 20 years told me this himself and he says that it is "conditioning".

And also, I'm not sure how you can 'masturbate to pedophillic stimuli' without already having a degree a sexual interest in the stimuli. I can't masturbate to pictures of donkeys since, with those photos, I can neither acheive nor sustain.

So I guess in in no imminent danger of 'turning into' a zoophile?
