He use to watch porn.. i would see it on the cable bill or active rentals but now nothing. I don't think theres anything wrong watching but it seems odd that he stopped.
Not all guy watch porn man. Some says it is degrading for women AND men to do adult films. Would you say woman is secretly gay for not watching porn either?
He is either madly in love with his wife, and she is his fantasy...or could just have a low sex drive. There is also the thought that he is alot craftier than her and knows how to hide it very well.
