I was without porno in December. Not long, just three weeks. It was okay. I even deleted all the porno from my laptop. But now I am downloading again. The only reason why I would consider a detox is the impotence caused by porno. I don't know if it is true but it sounds scary.
But I have said it before, if you guys want to get rid of porno and find it hard to do, try listening instead of watching. Put on the clip on your laptop, put on your headphones but close the screen. Listening a woman moan is quite powerful thing for me at least. Then slowly you can get rid of that too and before you know it, you jerk off without porno.
Just a thought.
