"Do you want to call me something specific?" She might not do the casual thing, but she wasn't hard up on definitions either. "What about... partner?" She wasn't sure she was sold on that either.
"You know what I do know though? Sex is a good way of reducing headaches." She waggled her eyebrows at him playfully, but clearly not pressuring him either.
