I figure “one man and one woman” is in the Bible for a very good reason. The good Lord knew that the stress of a multiple partner household would be too difficult to maintain.
Of course, I have fantasized about having “Brother Husbands”, lol. A plumber that landscapes as a hobby, an electrician that mechanics as a hobby and a doctor that loves to cook with a brother who is a veterinarian. They would all maintain highly successful businesses.
It won’t be the same polygamy, as what we see with the Mormons or Muslims. It will be group marriage, like a hippy commune with everyone having sex with each other.
