I actually agree with this all the way.
It actually doesn't matter what a woman says to me as long as she's honest. If you say "fuck me daddy" but in a way that sounds fake like a porn actress, it actually HURTS your goal of getting me to nut. Saying "are you about to cum" is the worst possible thing. It tells me that you aren't having fun with me and you just want me to finish.
I do like things like "I want you to cum inside me", but not when we're 15 minutes into an hour session where I get one pop.
Hell, you know what would be awesome? Just some generic-ass compliments that you mean. "You have a nice smile" or "you smell nice" would probably send me into overdrive.
