My girlfriend is the sort of person to set up all of these hoops for me to jump through before we can have sex where I'll ask what the hell she wants and she can't even tell me. Then she wonders why I'm "never in the mood." after I get tired of trying to solve the puzzle that is her sex drive.

Like imagine playing cherades with someone who wont tell you when you've gotten something right, won't even tell you what opening clues there are, but still gets pissed when you can't guess anything.
