Idk. Sometimes that's just something guys do. I agree I would rather them watch than cheat on me. But take notes and do what they do as long as its not too extreme for you. Trust me it works :-).
I explained to my hubby how it truly made me feel and when he actually listened to me he understood how I really felt. So he decided to stop and if he wanted a little extra to help him out sometimes he's ask me for a special pic or to help him in general lol
honestly, him watching porn doesn't bother me. and you cant actually force anyone to stop doing something. I'd rather my fiance watch porn than go out and cheat on me..
