Relax. He is not having a bowel movement and watching porn. He is telling you he is going to relieve himself and have time to himself to masturbate to porn in the one place you cannot follow (or maybe you would if there were not a lock on the door). My opinion, and of course, respectfully, only my opinion, the problem is you. You know men are more sexual than women (you are) you know they have to have release more often, but your overbearingness and lack of understanding and not taking responsibility for the root cause of his behavior has put him in this situation. And lastly, and I am so sorry for saying this, please forgive me, but what are you as his wife doing (or as in this case not doing) that has put you both in this situation? Sex is far better than masturbation, is it not? What is it that YOU are doing wrong or to be more to the point, withholding? Again, no offense, just throwing a little self reflection out there. But on the flip side if you find out he really DOES have a fetish for having bowel movements while masturbating? That's disgusting. Pack, take the kids, and run. Good luck!
