Different expectations than your partner while ttc

Did anyone have a massive difference in expectations when you and your partner started ttc?

Me: Starts taking prenatal vitamins, testing ovulation and bbt, starts eating healthier, trying to figure out the best times to bd. Doing everything I can to increase our chances.

Partner: thinks because people accidentally get pregnant all the time that it's going to be easy and it will just happen when it's supposed to. Doesn't think we have to have sex when the strip says I'll be ovulating. Doesn't understand why I'm bothering tracking everything.

For some reason, when I let him know we're getting close to the fertile window, he just never wants to have sex. He thinks it's a massive turn off to be forced to have sex but that's not what's happening. Nobody is forcing him to, but if we wanna have a baby, now is the time to have sex.

I started thinking, maybe he doesn't wanna have a baby but he keeps reassuring me that he does but we don't have to plan everything.

I'm only planning on having 1 baby, so I want to experience all of it, from the planning to the actual birth. I don't know how to help him understand this. A baby is a really big thing to me, I've literally wanted to be a mum since I was a kid. So now we're at the point of actually trying, I'm just so excited but I feel like my partner doesn't share that excitement you know?

I don't know how to express my feelings about the situation
