What am I supposed to do?

I don't even know where to start... My husband and I never have sex anymore. We have only been married a year, and the sex stopped before we even got married. We have had sex three times in the past year. I want kids so badly, I'm 36, and not getting younger, and he says he wants kids too, but you kinda have to have sex. I know he's not cheating on me, or watching porn, or anything that most people think of as to why a guy doesn't want to have sex... He says that it just makes him nervous. Yay! I make him nervous. 😥 he says it just feels awkward because it's been so long. I get that, I'm nervous too. But every time I ask to have sex, he has an excuse. I finally pretty much made him have sex with me two nights ago (after not having sex for 10 months). We were supposed to again today, because today is the first day of my fertility period. We both got naked, under the covers, he says "my back is hurting so you're gonna have to do most of the work." I said ok. And then we proceeded to lay there forever... And then I became emotional because how do we even do this? Where's the romance and the foreplay? I told him it felt like "eh let's have sex," kinda like "eh I gotta mow the lawn." So his idea was to fix dinner, wait a bit, then we will try again later. In other words, it's not happening. In every other part of our relationship, it's perfect, no problems, we love each other, don't really fight, etc. we have just lost all the passion. (And trust me there used to be plenty!)
