Dirty Talk?!

My boyfriend has resently started dirty talking during sex. I'm not into it at all I find it to be degrating when he swears and says crazy stuff. I told him I'm not into it but he says that it turns him on and he loves it and he just wants me to enjoy it? I'm no prude but  i don't like to hear fuck and bitch while having sex with the man I love. Anyone have advice?
