According to Barna Research, more than half of teens seek out pornography, and the numbers are much higher for young adults (ages 18 to 24). Even when they aren't actively seeking it out, nearly 80 percent of teens and young adults say they regularly come across porn. And yet, astonishingly, the vast majority of teens (79 percent) say they have no one in their life helping them to avoid pornography. And those who do are most likely to say it's a girlfriend or boyfriend rather than a parent or spiritual advisor.
