Brother husbands?

Finding it, and explaining it are the hardest. Brother husband's, male unicorns etc...I wish...seems not gonna happen in this life...maybe we looking in the wrong places ..but looking for single male/single female to make a quad ..

If I could start my life all over this is exactly what I would wish for.

I would assume that polyandry would be more common, due to the amount of single males wanting to be in the lifestyle. But, we have dealt with plenty of no-shows, flakes, and the non-performers; so, I assume most of these men wouldn't be able to handle a poly relationship when it comes to our experiences in the lifestyle. Plus we know of some male-unicorns out there that just don't want to be bridled. Currently, my wife has a girlfriend that they are committed to each other, and we are happy with all our relationships.

I would have to say that "Brother Husbands" is not that rare. I currently am in a poly relationship -triad. Yes, I am the new addition, meaning there is a legal marriage with my wife and her first husband. However, my wife considers me her second husband. Yes, I am straight, and not interested in anything sexual with another man. My brother husband is a friend, and we respect each other.

This is my second poly relationship. The first -where I was the second husband- was more of a hinge relationship. In that I knew there was a husband but we didn't meet... until my wife was tragically killed. At that point, my brother husband and I were able to meet and build a relationship remembering her. This type of relationship can easily have jealousy and scheduling issues. But, those times when my brother husband and I join together to pleasure and play with our wife together? WOW!

I hope that there are a lot of people into polyandry. Mostly because that is what I'm looking for.

Assumed by whom? Because I've seen nearly as many MFM triads as FMF, although the former are more often hinges instead of triangles in my experience. Or maybe they aren't. Hard to tell, since bi-phobia is a thing when it comes to men.

Why is poly assumed to be sister wives or multi-couple. Is brother husband really that rare?
