It was the accepted practice in Babylon 4000 years ago that for a month after the wedding, the bride's father would supply his son-in-law with all the mead he could drink. Mead is a honey beer, and because their calendar was lunar based, this period was called the "honeymoon."
In ancient England a person could not have sex unless you had the consent of the King(unless you were in the Royal Family).

(Fornication Under Consent of King) on it. Now you know where that came from .
