Yeah, but you wouldn't say to your girl friend "That dress turns me on", right?

There's quite a difference between "that's sexy" and "it turns me on". I'm a man and I could say "Wow, George Clooney is really sexy"... but I would never say "He turns me on" :-)

Thus, a woman saying "You cleaning up turns me on" sounds a bit like baiting. A more honest sentence could be something like "You cleaning up makes me feel better"... but it wouldn't have the same effect on the man, wouldn't it?
