Harvey is frequently smooth personified. "Sweating is sexy?" he asks. Yes, he is toying with her. How will she learn otherwise?

The wicked grin that bends the corners of his mouth probably don't help her speechlessness at all. And yes, he is rather proud of this particular accomplishment. This might be the one time he wishes that ridiculous, headache-inducing power he had for a short time was still active. He might not be able to hear what she's thinking, but from the emotions he'd be getting, he'd have a pretty good idea.

"Is something wrong?" he asks her, as though there hadn't been a semi-sexual encounter just seconds ago.
