In some cultures, polygamy is allowed, and sometimes even encouraged. If we assume that this is morally fine, what are the moral implications for two of these women (both currently married to the same man) to have a sexual relationship with each other? How often does this occur?

I had been reading a book, a modern retelling of the story of Rama in his youth. He had 3 mothers. It was common in those days for a king to have multiple wives and even more concubines. Snap to the present day.

It seems unfair for polygamy to be allowed, but not polyandry. In a society that practices polygamy, what can the women do? Marry their co-wives? How does society look on that?
