How does lifetime baby fever affect a woman's sex drive/life?

I have never been a huge kid or baby person and have generally had a high libido for most of my life, and my husband and I have wanted to take a few years to just enjoy romance and time alone before considering kids, so as a person who repeatedly gets asked when I'm having kids, I genuinely have a lot of questions that I don't feel are appropriate to ask my conservative baptist cousins about how it affects their sex life. Did you mainly get married with the intent on kids, or sex? Do you only have sex with the intent and excitement of making a baby, or do you actually do it for fun? When you are done having kids, will you no longer be interested in sex? I hope I am wrong, I just cannot imagine getting married with the sole purpose of reproducing. That has to make the husband feel oh so special and loved, especially if sex is only for the purpose of conception and not for connection.
