This is a topic I can speak to as I am a recovering sexual addict. Yes the "easiest" to handle a porn problem is to avoid it. Un plug your tv, disconnect cable and internet, don't buy porn mags and so on. You can believe me when i tell you those things don't work. You see sexual addiction is just that an addiction. Internet filters are great and can prevent a porn addiction from forming in children during their formative years by not allowing it to enter the house. But then they have friends and their friends have computors and boys especially are very curious about a womans body.
If you are trying to avoid porn from coming in via the internet I recommend the {no override filter from besafe. com} this filter is supported by the AFA - American Family Association. If porn has already impacted you life I recommend finding a christian sexual addiction and recovery group where you can be equipped with the tools to control and overcome sexual addiction. I also recommend a program called covenent eyes. Covenent eyes as a reporting software with tells the person you are accountable what sites you visited and flag any that are questionable making you give account for your actions.
Then you have what I have. When I fell I hurt my wife terribly. Trust was gone as you can imagine. I did join a sexual addiction and recovery group and even started a biblically stronger version of the group later. My wife put a program call Spectersoft on our computor and I am glad she did. Spectorsoft is a screen capture software with shows everything your computor screen sees. So no using your computor as a dvd player for porn. The program has a stealth mode which you will not be able to find once it is activated without knowing the right sequence of keystrokes. 2 years and 9 months later I still don't know how to access it but in truth I have never tried to find out either. So in addition to being accountable to my recovery group I also have complete accountablity with my wife in regards to my online activities which is where my weakness was.
Self control is a kind of insulting thing to say so someone seeking recovery. Its not that simple. Like any addiction it didn't happen overnight and the cure will not happen overnight either. Often there are deep emotional issues attached to the addiction which a person may not even be aware of. Now some will tell you something like, Just pray for God to take it away. I will not say God can't or won't take an addiction like this away but He usually doesn't. The addict has become so dependant on the object(s) of their addiction and the ritual of the addiction that God most often will take a person back the long way. In doing this we can return to dependence on God for guiding our lives instead of insisting on doingit ourselves. As you can imagine its not a fast process but it is worth it.
