By age 12 or 13, the average American boy has seen thousands of vaginas and thousands of sex scenes through pornography.
"a boy by the time he's 12 or 13 has seen thousands of vaginas, has seen thousands of sex scenes. That's average for America right now." (said at 2:07:53)
No scholarly publications matching or verifying the claim that the average 12- or 13-year-old American boy has viewed 'thousands of vaginas' and 'thousands of sex scenes' could be retrieved. While surveys of adolescent pornography exposure report varying rates and ages of first exposure (typically around ages 11 to 14), specific quantifiable claims asserting that an 'average' boy has seen thousands of individual scenes/images by age 12 or 13 are unverified in empirical literature.
