Do parents realize nearly every teenage boy watches porn daily?

I would say at my school, 90% of guys from 13 watch porn. Having an age limit is just pointless. Parents say "It gives them the wrong idea about sex and love" yeah no teenager is actually going to try and seduce there friends mom, and if they did they would learn there lesson very fast. And at least we have a decent idea how to have sex the first time we do it. I bet so many [arents reading this will go "No not my son" I LOL at you. Unless they are religous or extremely straight edge and nerdy.
