Go for 90 days minimum. The results are mind blowing. You may never want to jerk yourself off again, and definitely will never want to look at porn again.
Think about it. Your fathers looked at some playboys. They got to see a few pictures of naked woman otherwise they needed a real chick. Your grandfathers only source of porn was a chick they had to meet in real life and try to get her to do nasty shit.
Now you beta fags get on your computer and look at 1,000's of enhanced images and unreal videos for hours and hours, night after night, week after week, year after year. You think you haven't done any damage?
I think porn is the cause of the pussification of men.
