I hope you're joking...that would be a childish thing to do and it would only piss her off.
She was at the very least being honest with him, that her "no" is a knee-jerk reaction response...and giving him the info that he stands a better chance of her not saying "no" if he continues to try to arouse her and not ask if she wants to fool around etc was very forthcoming of her. She was communicating to him in her own way that she's a arousal=desire person; that's valuable info for him.
How would you respond if your W dropped that little kernel of insight for you?
