Well, not males ones apparently.
University of Montreal researchers wanted to compare the attitudes of non-porn watchers to regular viewers.
But researcher Professor Simon Louis Lajeunesse told the Daily Telegraph they simply couldn't find any.
"We started our research seeking men in their twenties who had never consumed pornography. We couldn't find any," he said.

After reading that I got a bit curious. Did they just not look hard enough, or does access to the internet guarantee porn usage? At least for men. So, query: Are there any men on the Escapist in their twenties or older who've never watched porn?
