That actually sounds like heaven
Well, if you don't mind novels, the Anita Blake, Vampire Hunter has lots of poly-amorous relationships
It's all about the preferences of the fan base. In the real world, I don't care what people do in the privacy of their own homes, provided it's safe, sane, and consensual for all parties, but I personally do not like polyamory, and don't care for it in my fiction. For those of you who do like it, make it known in legitimate forums, so maybe the authors might take note.
That the thing. In general i dont enjoy polymourous relationships since they seem unequal and i rlly dont like they thought of 'sharing' the person you love with others, which is usually the situations depicted in fiction. But if everyone loves each other, im good. I just like mutual love and affection. I dont typically enjoy poly but the ideal would be for everyone being happy and being equal.
Sigh one of these days imma find a polymorous(threesome) couple in manga where everybody loves everybody. Not 1 seme to two ukes. Not 2 semes to one uke. Just everybody is in love with and intimate with all parties involved. Even in hetero romance i would love to see this. The usual love triangles and harem members who all hate each other cause they are rivals in love is tiring. Only examples i have is Canis second season( yaoi manga with 3 orphans who all mutually love each other and have threesomes) and Iron blooded Orphans(only a little romanxe but two girls get involved with mc and instead of rivalry they bond and love each other plus him) its great.
