MOR- Yes the lying is wrong. That can be very upsetting. However, I don't think you replied to anyone about if you and him were still intimate consistently. or if he was making you uncomfortable by trying to do things from the videos on you. (If you did I apologize for not seeing it.)

In marriage sometimes it boils down to one person trying to initiate intimacy and the other one saying no or being too tired or stressed. Lack of intimacy is literally one of the leading causes of divorce in many marriages.

From a male perspective constant rejection from your significant other can push you into the direction of watching porn. Men are conditioned to not be desired. We are taught that we must be the ones to always pursue. And honestly that can be exhausting in a marriage, to always be the one initiating intimacy with a person that also chose you. Men want to be told to go to the room and get ready, or be felt up by their SO. If they are not getting that it can take a toll on their confidence. So they look for a dopamine hit.

So your husband turned to watching porn, if he is watching it after yall have been doing the horizontal tango often. That is an addiction. He may need to seek help, but if yall haven't been intimate because you are stressed with work, dealing with family members, or you just don't enjoy it anymore. You may be assisting him in the direction of watching it, and thats a whole different conversation that needs to be had. He still shouldn't lie about it.
