The problem is with modern men who believe a wife has a right to starve her husband of sex. As a truly enlightened individual, I would never let my marriage get to that point. I will get downvoted and possibly banned for this, but marital "rape" rarely ends in conviction. A woman won't leave her husband for desiring her TOO much.
Or they just have a belief that makes it wrong to have sex outside of marriage. My wife was a virgin who wanted to wait until we were married and I was okay with that. Now we're married and she wants to do it every day.
Lol I'm guessing that was a conversation about stepfatherhood, not the same situation as OP. But I'm pretty sure most people don't want to be step parents either, and will accept it if you say you don't want to be a stepdad.
