I suspect 90% of teenagers currently go to fairly safe porn sites like pornhub, rather than diving into murky underworlds of bestility c, child porn, and sites requiring things like 'nudes for porn' or something. You're not going to stop teenagers getting porn, or adults for that matter (in the 80s kids were sharing dad's playboys)
