Psychologists suggest America's fascination with incest stems from sexual excitement spurred by the thought of breaking taboos. They also say it could be because of an interest in 'novelty'. Dr Peter Kanaris, a psychologist and sex therapist in Long Island, told DailyMail.com: 'The initial interest in incest porn is taboo so, therefore, that increases the excitation around it. 'America also has a less open society [when it comes to discussing sex] than other countries. 'When I go to conventions, there is research from Canada and overseas [on sex education] - but not so much the US. 'That's because we are dealing with religion and a series of inhibitions there that only heighten the interest in the taboo.
