A representative study in 2014 by the Barna Group found that “eight out of ten (79%) men [in the general U.S. population] between the ages of 18 and 30 view pornography at least monthly,” as do “two-thirds (67%) of men between the ages of 31 and 49” and half of men between fifty and sixty-eight [!!!]. “Three out of ten men (29%) view pornography daily,” even though many realize it’s a problem. Asked if they’re addicted to porn, “one-third (33%) of men between the ages of 18 and 30 either think that they are addicted or are unsure if they are addicted,” and “18% of all men either think that they are addicted or are unsure if they are addicted to pornography", which equates to 21 million men.
