My mans to quiet

During sex I love when my partner talks dirty and moans. 
My current boyfriend of 2 years is amazing in every way except that he never makes a sound during sex. 
I've tried talking to him about how much it turns me on when he talks dirty and moans and he still doesn't do it. 
We use the pull out method and he says that if he talks dirty it makes him to close to cumming. I've suggested that we use condoms so he doesn't have to worry so much but he doesn't like them. Also, I am unable to take the pill because of certain medications I'm taking. 
Any suggestions as to how to get him to be more vocal during sex?
