It's not on the list, but that one is definitely common, too. Whenever someone says they have a direct line of communication with a deity, you just know there is a good chance they are going to follow up with: "And I just got off the horn with the big guy and he says I'm allowed to bang anyone I want."

add to that - its not "sleeping" .. it is sex.. sometimes very energetic sex. Sex activity is deeply tied to social constructs, and at the same time powerful forces of the mind and body in a very personal way .. sex activity in a group like that has been the raison d'etre of many orthodox religious orders.. anti- that is, to ban and demolish that, basically.. because it does work.

Approximate line from the Waco miniseries on Netflix: "Why is it, that whenever God speaks to a prophet, it's always to tell him to have sex with a bunch of women?"
