I understand how sharing is caring, but I don’t think that applies with sharing a wife. It’s called fraternal polyandry and fortunately it’s not very common worldwide. Amar and Kundan Singh Pundir are both in their 40’s. Having 2 husbands isn’t that bad compared to her friends, some married 3 and others married upto 4. It depends on how many brothers are in the family.
The three couples have three children, they don’t care which father is the biological father. The children just treat both fathers as their own. This tradition has been going on for ages and it doesn’t look like it will discontinue any time soon. It might look odd to us, but in their village it’s very normal. As for the curious question of how do they go about mating,
We make shifts, change shifts and sleep on alternate days. We have to make shifts otherwise it won’t work.
Be grateful you don’t have to share your wife with a younger brother.[Source]
