Nothing turns off sexual pleasure faster than nervous chatter. Go ahead and make noise, but don't use coherent sentences. You want to shut down the rational brain and let the body take over. Personally, I like having sex with guys who speak other languages. No matter how much they talk, all I hear is the emotional content, and don't get distracted by the literal meaning.
Dirty talk can turn some people on, but turn others totally off.
I suggest you avoid it on your first time. They temporarily turn pain into pleasure. You could easily damage yourself. You can pretend to sniff them if your partner seems to think them necessary. Getting into a spiral of wanting ever bigger cocks is not such a hot idea.
