wow! thats definitely a difficult situation. i agree that you should talk to your wife and explain to her how this is affecting you and your relationship. i am a strict disciplinarian and i wouldn't stand for that nonsense one bit, so i understand where you are coming from. she really needs to get on the ball and do whatever is necessary to stop that disgusting behavior, because i must say that is very disgusting, especially since you guys have already confirmed that he does not have any medical ailments that is causing him to do this. wish you the best of luck.
