I mean harem. If a man can have one (technically) a woman should also be allowed to have multiple husbands.
Society has assigned gender specific roles.
It is better to follow them, otherwise it will collapse.
I have a question, what about other husbands when she gets pregnant? IYKYK.
Plus, can female provide shelter, food, and other needs to her husbands and children while being pregnant?
As you know, she has to work 8-12 hours a day.
