It has happened, but not until my son was about 16. I calmly told him that it was natural to be curious, but to be aware that a lot of what you see on the internet and in magazines is NOT what real women look like and is CERTAINLY NOT what regular people do. (There is some seriously sick stuff out there.) I cautioned him about viruses and malware on some of the websites, too. He was mortified (and so was I), but he at least became more circumspect (and quit using MY computer for this stuff!). While he was home from college over Christmas I offered to help him clean out his closet, but suggested in advance that he pack up and relocate anything he didn't want me to see. LOL!
