Synonym for postcoital

Unusual request, I know, but does anyone out there know the synonym for postcoital, the period after orgasm--a term other than sexual resolution? It drives me crazy when I can't recall a word. (I believe its first letter is "c".)

If the sexual activity was good for her, then "Afterglow" works.

If the sex was good for him, then "zzzzzz" is probably appropriate.

If the sex was great for both, then:

"Oh! My! God!!!"

Should work.
