In the fantasy world of “barely legal” pornography, the teen girl is an ingénue longing for sexual initiation at the hands and body of an experienced older man. For an older man (the average male porn user is over 30) perhaps intimidated by the erotic and emotional demands of his own female peers, the imagined naïveté of a much-younger woman is a source of comfort. The less experience she has, the less likely she’ll mock his clumsiness and the more likely she’ll appreciate whatever savoir-faire he does possess. (from Why Do Men Love ‘Barely Legal’ Porn?)
