Talking while having sex

So I feel incredibly uncomfortable talking in my first language while having sex, but I also want to be able to tell my man when I like or don’t like something. We have kind of a language barrier because even tho we talk the same language we have different dialects and sometimes we can’t understand each other and that’s what makes me so uncomfortable. I have an irrational fear of not being understood so him asking me to repeat stuff makes me super anxious and that’s not exactly good when you’re having sex. I do want to ask if we can talk in English while having sex, but is it weird to talk English during sex and then your first language outside of sex? Hoping someone that has experience will give me some answers.
