Well, WB, no one ever told you that your wife would begin communicating with you about sex VERBALLY.
It looks like she is communicating, all right, and it's not in a way that you find particularly comfortable. Too bad, I say!
I think you should leave it alone for a while and when new positions become the norm, instead of a freakish thing she had to really work herself up towards, then perhaps you can broach the subject and tell her how enjoyable you find her. Build on the positive.
As long as she is communicating somehow with you, I'd leave it alone. The only thing I'd find intolerable would be silence and no discernable change in behavior.
IOW, don't look a gift horse in the mouth.
Come on, you're a mountain man, I shouldn't have to tell you this.
