It depends. "You make me so hard, I'm going to fuck you silly" is awesome. "Choke on my cock you dirty whore" is not. But that varies from woman to woman.
I tend to be pretty vocal regardless of the company because it turns me on. And you mentioned tedious? Well, 20 mins of the same thing over and over again is just.........an example from my real life, this guy kept saying "you like my dick don't you" which sprinkled in here or there is fine but not every two minutes. After about the 5th time he asked I really wanted to say "Not anymore!"
