The first thing I had to admit to myself is that I'm an addict, I don't have the luxury (if there is one) to casually watch porn. I dunno if there are people like that, who watch porn like once a month and don't even care much for it. I was never like that, as soon as I discovered porn very young I became obsessed from it, always trying to find it whenever I could and keep it hidden like Gollum keeps his ring. It's so true half measures are not possible with us addicts, we have to go all the way, and we can't ever go back to it.
Delete it, or it will delete you like person. Be free and shift + delete. "...and just keeping the really good stuff just in case" What case? Case of weakness and misery for sure.
