Starting a post with an accusation of rape isn't really a great starting position, and frankly I find it disturbing that the default assumption is that it is likely I have pressured someone for sex at some point in my life. I have accepted a "not right now" as a no for as long as I can recall, and the idea that someone might actually suggest that "asking for consent ruins the mood" is, frankly, insane to me.
I did take a moment to reflect, and came up with nothing. I can think of one instance where I tried to initiate, but I felt my partner tense up before anything really happened. What happened next was I immediately stopped. She didn't even say no, but I knew she didn't want to continue.
I'm sorry your husband committed rape, and that you have apparently internalized the idea that all men are probably rapists to perhaps help accept that fact. I am not.
