Look, it might sound crazy, and every situation is different, but there may be some insight in this. I am going through a divorce after being with a woman who, for a time, didn't want sex, and if I was caught with porn, she made the relationship even worse. She cheated on me eventually after putting me through months of hell. She allowed me to spend hundreds of dollars on marital counseling meanwhile, cheating on me. And all of it, for me, stemmed from feeling rejected in bed. Nothing I did could fix it. Nothing. Sorry if that sounds depressing, but I went a long time in denial. Looking back, a lot of people, specifically on reddit, we're right. Nip your marital issues right away. Don't wait. You have no reason to feel rejected by your wife. Figure it out right away. Before some other douchebag takes advantage.
