"An addiction to pornography can happen in as short a time as six weeks if watched for 10 hours or more each week and if the person has a predisposition to addiction," said psychologist Brenda Schaeffer. This article also brought up a good point saying how easy it is to come across porn. I know when I’m doing homework research or on Myspace I get pop ups all the time that are inappropriate. You don’t even have to go searching to find such sites, they come to you.
