This is pretty unlikely. There were studies done but they should be taken very lightly. The respondents may have said what they don't mean just because they thought it was cool. I mean come on, high school guys shooting their mouth off about sex? And even if they meant it, there's no way to gauge if they would actually follow through given the chance. Surveys have to be treated very carefully, and with such a loaded topic I would be wary of taking it at face value.
As for that site, it looks like a lot of hysteria. Oh, it was so bad then and so much worse now because of naked pictures. I see causal connections wherever it suits me!
