Does dirty talk make you uncomfortable?

For me dirty talk makes me uncomfortable and feel extremely awkward. My SO only does it when were having rough sex but anytime we do and he says something in my head I'm like "oh god, why'd you say That? ewwww nooo please stop" but I of course play along with it. I don't know if it's my fear of not being able to talk dirty and saying the wrong thing and looking stupid. Sometimes I literally don't even respond and moan instead hoping it's satisfactory enough but he repeats himself or says "huh? what was that? say it louder" and I just cringe every single freaking time. anyone else struggle?
