Startling finding regarding young men and porn

From the November 2009 issue of Psychotherapy Finances:

The problem with trying to study the effects of pornography on young men, researchers find, is that you can’t assemble a control group. Professor Simon Louis Lajeunesse from the University of Montreal explains: “We started our research seeking men in their 20s who had never consumed pornography...We couldn’t find any.” The average age at which his subjects first watched porn was 10, Lajeunesse told The Telegraph (Britain, December 2). Roughly 90% of their “porn consumption” was via the Internet...Meanwhile, according to a Nielsen survey quoted in the November/December Psychotherapy Networker, 25% of U.S. employees admit to accessing Internet porn at work. A long article about the effects of pornography titled “Out of the Shadows” is available online at www.psychotherapynetworker.com.
