Re: Struggling man looking for advice
OP, I have been the woman who had zero interest in a sexless marriage. The worse thing you can do is nag about. There is absolutely zero chance of things improving if you do and a very strong possibility it will actually get worse. When a man nags about sex, it reinforces in the woman's head that he doesn't care about her feelings and is just interested in getting his rocks off. Most importantly however, it makes a man look weak. Nothing more unattractive to a woman than a weak man. Once a woman begins to perceive you as weak, it is very damaging, it is difficult for her to change even her own perspective. Furthermore, to shut you up, she will start giving you pity sex (I see this has already happened once). Do not accept pity sex. You do not want to know the things that run through a woman's head during pity sex. Again, it is difficult as a woman to begin to enjoy sex later on down the road after an extended period of pity sex. So if you want to not make things even more complicated than they already are, stop nagging her for sex.
Like your wife, I told my partner exactly what was wrong and suggested things that he could do to make things improve. She has told you: "She wants me to not discuss things that are bothering me like our sex life. She does not want me to bring up things about the pregnancy." Have you tried that at all? It's only been 2 weeks, give the woman some time. Seriously, put yourself in her shoes. She's pregnant, that is a pretty big deal, especially considering she did not want to get pregnant. She wants to be consoled, comforted, reassured that everything will be ok and you're in her arse about sex. Understand that you making the focus on you and your need for sex will be read as you being selfish and only caring about your feelings.
Clearly sex is one of your top love languages. Do you know what her love languages are? For many women, while sex is a love language, affection and intimacy are even more critical and lay the foundation for satisfaction from sex. If you do not know what her love languages are, it would behoove you to read the 5 Love Languages and His Needs Her Needs. I would reckon the conversation starters in there would be an excellent way to get the focus away from the pregnancy/your need for sex (the two issues she specifically asked you to not talk about) while addressing what each of you can do to better communicate your adoration in each others language.
Listen to your wife OP. She may not be spelling things out how you would like but if you learn to listen, you will see that she's telling you exactly what she really needs right now.
