Confess it to your imam. (I apologize if that's not the right term for it. I mean to say your spiritual teacher.) There are groups for sex addicts that go through a 12 step process much like Alcoholics Anonymous. Go to one of those groups with the support and prayers of your imam.
In the meantime, there is a book called "Po*nified", available on Amazon. It is a good book about the industry and the effect it is having on our society. Think about the individuals involved. Sure they are fulfilling a contract that they chose to enter into, but how voluntary is it? Maybe they have an expensive drug habit to support, or their parents did not provide for an education and they do not know how else to support themselves. I'm not saying everyone in the films is like that, but many are.
Depending on the source of your, um, entertainment, you might try installing a filter on your computer. There are several available on the market that help make smut inaccessible. Have your imam or a good friend set the password.
My final bit of advice is to think about your life. Think about your short term, five-year, ten-year, and lifetime goals. Think about the kind of person you want to be, and what you want to be remembered by. Write down anything you discover about yourself and keep it somewhere you can refer to it from time to time. It takes 28 days to build a habit, and the first three are the hardest. So take it a day at a time, and in 28 days you will be that much closer towards being the kind of person you want to be.
