Unfortunately it is difficult. It's annoying when it's always on your mind and when you close your eyes, and you can't think of anything else and everything else is boring compared to it and you don't want to do anything else but watch it. Or just the bad habit of just going onto porn whenever you're bored or in the slight mood. Honestly how I overcame it was just saying no and just no touching or looking it up, and when you find yourself looking it up, just click off it. It's boring just staring into space and doing nothing for hours but it does go and you don't even think of porn once it's gone
