Sex and Condom stats

I am suprised to read these stats, because they do not coinsed with the stats of other web pages, infact they are almost opposite. "College students between 18-22 who live on campus are more likely to use condoms then people who have more partners" ... They say that the more partners you have, the Less likely you will use protection. The stats dont line up with all the information given by CNN and Newsweek... who do we trust? This artical gives some supporting evidence to make it credible, but when one asys against major sources, who do we believe?
In short, BE SAFE!!
