Before you go jumping into another religion, please take some time to get to know yourself. First of all, consider your age, marital status, and type of pornography that you think you're addicted to. You may want to work this out with a therapist. Then consider what type of profession you would like to pursue. If it's not a trade, then get yourself enrolled in college. The reccommended reading list of books by Ray Franz and Steve Hassan is a good one to start. Most of all, just take your time to make good decisions. Now is NOT the time to panic.
The kind of porn you view and whether or not you're addicted to it is ot my business. But if you're like many other young men who have posted here, just watching human beings having vanilla sex drove them mad with guilt. The same goes for masturbation. The Watchtower turns young people against their own bodies. It is normal for people to express their sexuality. If one doesn't do so, then a substitute will always be found. Do some research on masturbation and the type of porn you prefer. Find out if science say it is perverted or unnatural, (ie with animals,children, rape, etc).
