Quoting Wanna Touch My Flower?:" If you're married (or with, have been with, etc...) to someone who has a porn addiction, how do you handle ... [snip!] ... the crap, whatever, but in the meantime, how do I not take it as a personal attack? Because that's what's going on here...."
if its an actual addition i recommend counselling....just like for any addition. have you set down and talked to him about it? My SO use to watch porn a lot..not addicted though. i didnt like it. i felt intimidated by the perfect bodies all those girl had. but most of all i didnt like the fact that he was getting off to someone besides me. im the only person who he need to get off to. i gave him sex all th time so the only time he used it was to masturbate...i still didnt like it. i set down and explained the way i felt and why. he disagreed but understood. he said he wasnt going to watch it anymore unless i decided that i wanted to watch it together ( im not a fan of porn so no). we made our own videos and pictures that he could masturbate to. he hasnt watched it in a year. no problems. good luck
