Hundreds of pics

So if you have an iPhone there is a feature that allows you to put pictures in a folder called “hidden”. Last night I was looking for a picture that my husband took on his phone so I could send it to myself. Apparently this man has over 700 pictures of naked women and people having sex in this “hidden” folder. We don’t have sex hardly at all and he’s been known to masturbate very frequently. Now, none of this would bother me if he could just be honest about it. He lies and acts like I’m crazy when I find his cum rags in places like the garage and the car. He gets so upset and won’t even talk about it without going off the deep end. He knows I don’t like him looking at other women and it hurts my feelings that he would rather be with his hand than with his wife. My question is: Should I confront him and tell him what I saw and how I feel? Or am I overreacting and wrong for going on his phone?
