I understand how your wife feels,I hate porn and my hudband knows that I do.I've tried to meet him half way and watch it with him but thats still not enough.I dont know if you still watch it or not.But if you do and your wife finds out you have she will feel more upset.It's not enough that she feels like she is lacking something you desire.It will make her feel like her feelings dont matter.It's all about you in other words.Another thing you may not have thought about is that she may not be withholding sex to punish you but to save her own feelings.What I mean is that if she is hurting and upset over this then all it would take to make her feel worse is for you to say something while having sex that she thinks sounds like something from a porn.It can make her feel like your thinking about someone in the flick.Then she is no longer in the mood or just completly turned off.Thats my thoughts on it anyways.I will say one thing though.If men took half the time on there partners as they do looking at porn I dont think there would be as many women that hate porn.See alot of guys can take hours looking and searching for porn but then they dont take any time to talk to there partners.Women need to have a connection with there partners.Where most of the time a man just wants the sex as long as he is happy he thinks the woman is happy.So heads up guys thats not always the case.
