I am a man, and when I read this, my first response was that it meant "not messy" as in: tidy house, tidy car, etc. It would have taken a huge stretch of the imagination for me to decide that it meant "bathed enough for oral sex."
For example, my wife doesn't keep her car clean (It's full of wrappers, empty water bottles, etc.) and it drives me nuts. Much more so than if she hasn't just popped out of the bath.
Maybe, just maybe, men think they are being asked a different question here? If I was completing the questions, I probably would have included it in my "can't stands" as well.
