I can't figure out this crazy idea of having babies

The farther I get into my marriage, the more I fear the idea of pregnancy. I am supposed to start taking pre-natal vitamins. I have bought them. They are on my kitchen counter top, staring at me. I haven't touched them yet. I am freaked out.
I need to be completely honest and say that every time I hear people talk about all the misery of pregnancy and child-birth and child-rearing, and then put an idiotic smile on their faces and say it is all worth it, I can not help but think they sound pathetic.
Seriously, do people turn stupid after they had children? So you go through nine months of misery, plus the pain of labor, plus the endless sleepless nights with a crying baby that can't say what it wants, plus the fact that your body will NEVER be the same again, so that what? Your child can grow up and treat you like you treated your parents? Really? Is that what you want for your life? If human beings had any sort of self love they would not procreate.
On top of it, this child will blame you for everything wrong that happened in his life, while everyone else will talk about how their children would never get away with that. 
Oh, let's not mention sex. How often to post-baby couples have sex?
People say you should take advantage of it now, because you won't have much of it after the baby. Hold it, buddy! Are you trying to talk me into it or out of it? I love sex. I actually don't think I love anything more than sex. Maybe potato chips. And I already don't have enough of it. I don't need an aggravating factor to my already pitiful sex life.
I am quite honestly hoping for God's mercy to not allow me to bear children. This way I don't have to give up my body - which has never been a top model body to start with -, my trips, my life, but I don't have to be the one making that decision.
