For the Exodus people, I set up a simple set of rules for the "wilderness" marriage relationships. Here was the agreement: The woman agrees to not have the kind of sex that creates offspring; what my webmaster calls "PIV" sex, or "penis-into-vagina" sex; with any other man than her husband. In exchange, the husband must provide every need that woman has; including but not limited to food, shelter, and complete sexual fulfillment.
