Chuangshen

Chuángshén (床神 "Bed God") is the Chinese deity of the bedchamber. It articulates in a couple of male and female deities: Chuángmǔ (床母 "Bed Mother") and her husband, Chuánggōng (床公 "Bed Lord").

They look after the bedroom in all aspects, including sleep, sex, childbirth, recovery from illness, and rest.
