Yeah too much porn can screw with you. In some cases guys that get addicted to it find themselves unable to get of to normal sex because of it. It basically messes with your preferences I guess. That can be fixed by giving it up. Usually a month without it undoes everything.

You might try setting up an internet blocker and using it to block all porn sites. Give it an annoyingly long password that you can't just remember so that it's more difficult to get access to it.
