I do wonder how much of an effect the internet is going to have on our current generation of kids. I mean, even in my youth (1997-2003 middle school through high school) I didn't have this kind of access to videos of any content.
Last year on the last day of school, I had a period with just 6 boys. They were talking and I noticed the conversation was going South, but instead of hushing it up real quick, I asked a question.
"How many of you have seen a video on the internet that would be considered worse than R-rated?"
The response?
"By the time I was in the 7th grade, I could tell you the top ten best sites to watch full length porn videos."
Also, one boy told me about how in the 6th grade, his older brother showed him a video of a guy defecating and urinating on a girl before having sex with her. His brother thought it was funny.
