It is ironic. I have no data on this, but I would guess that having sex with the same gender is far less common than having multiple sexual partners, so why have we worked so hard to normalize and legalize same gender relationships while giving no thought to polygamous relationships?

The legal frameworks have to do with property transfer and responsibility for raising children, both of which are much more complicated in relationships with more than two partners.
