Should children be taught that porn is not real?

Many teenagers regularly view porn. But does this give them a distorted view of sex and relationships, and is there anything that can be done?For many parents, the idea of their child seeking out, or stumbling across, online porn is the stuff of nightmares.But with many children’s bedrooms equipped with computers and the proliferation of the smartphone there are plenty of parents who would accept the inevitability.There is no clear statistical picture as to how many children access porn online, or how often they do it.In 2011, an EU-wide survey found that a quarter of 9-16 year-olds had seen sexual images and only 11% on websites.
