Ted blinks and smiles at the way she describes it, at once both academic and incredibly romantic. And also reassuring, that she really does find it incredibly special, just like he does. It wouldn't have been the end of the world if she didn't, as long as she considered their relationship itself to be special and important, but it makes him happy that she does.

He's never figured he was blowing her mind with his skills in bed alone. Sometimes he's a little insecure about it, but hearing her talk like this helps. He hopes and thinks that what it really comes down to his attentiveness and his dedication to making sure she feels good. Which is something he has up on those guys she's had casual sex with. The trust and the communication and the familiarity.

"Do you miss it?" he asks curiously. He tries not to let any insecurity creepy into the question.
