What polygamist societies incorporated homosexual acts and orgies into their marriages?
OP basically answered his own question in the first paragraph. He had a threesome and automatically equated it with polygamy. That ideology is the very reason it could never work. Most modern Western men would only see it as "I get to have wild sex with multiple women", and most modern Western women would (rightfully) see no benefits in the practice.
How would polygamy work in the West today when some men can barely find it within themselves (or their bank accounts) to financially support their kid(s), let alone multiple wives AND children? And that's pretending for a moment that polygamy would be practiced equally across all socioeconomic lines which we all know would never happen.
Because don't think for a second women would be convinced to agree to this only to continue having to work and split the rent with a man and her sister wives. What woman is going to agree to be a second or third wife to a man and still have to work, when she can remain single and support herself? Only the top tier men - who many of y'all already complain about - would be able to engage in this. So where does that leave the remaining 95% of men?
