Pornography could be creating sexual interest in children, according to experts. “Clinical experience and now research evidence are accumulating to suggest that the Internet is not simply drawing attention to those with existing paedophilic interests, but is contributing to the crystallisation of those interests in people with no explicit prior sexual interest in children” (Wood, 2013). In Internet Pornography and Paedophilia, Wood writes that there is growing evidence that the Internet and social media "act as a catalyst, facilitating an interest in sexual images of children.” “From a clinical perspective, it has been evident for some time that there are people seeking psychotherapy who have been accessing child images, who appear to have no explicit or crystallised sexual interest in children, prior to access sexual materials online.”
