Seeing as how I've seen my parents' internet history...
I don't think it would matter.
I did get in a bit of trouble with my parents when I was younger, because I discovered pornography when I was about 12 or 13 or so and housesitting for a family friend, and spent oh, I'd say 8-10 hours just seeing what was out there on their computer. The family friend called my parents up once they got home and logged onto their computer, and I had to go over and apologize. Said family friend was the person who then showed me how to hide my browsing history. Nice lady.
