"I, uh.. wouldn't mind trying more stuff like that," he adds, which makes him blush a little bit again. He leaves the request vague, partly because he's not sure what he would even ask for, and partly to let Joan make her own suggestions. She's clearly a lot more comfortable and familiar with this sort of thing than he is, which makes it a lot less daunting. Not only will she not be embarrassed, but she'll also take the lead so he doesn't have to. That in itself is somewhat unfamiliar to him.
