Are there any fics that feature Dean discovering that Castiel has brought him back just a little too perfect?

Like maybe he has regrown his tonsils and they become a problem later on, or he suddenly discovers he possesses a foreskin, or I dunno, John never told him he was born with six toes. Whatever. Something natural about his body that he's learned to do without, suddenly back again because Cas made him completely whole.

Bring it. Please and thank you.
