My SO has a son from a previous relationship, and his mother recently caught him looking at girls butts online. He's almost 11. And like it or not, with technology today, our children have very easy access to porn no matter how high you set parental restrictions. I am very proud of my SO for not only discussing sex with his son, but for also explaining to him that porn is created by models and actors who are paid to do things most girls wouldn't, and they don't look like most girls you'll actually meet.
