In the Netherlands,Polyamorous relationships are common. That means that both partners can have other lovers,usually forming close relationships like an extended family. Polygamy probably wouldn't be too popular there as Dutch girls are far too liberated for that nonsense.<quoted text>
The ideas are in place. Consider this:
"A former Dutch MP has admitted that polygamous marriage is the "next logical step" following the introduction of same-sex marriages in the Netherlands.
Speaking to the French online magazine, Yagg, Boris Dittrich said there was now a movement in the Netherlands to introduce multi-partner marriages." http://www.christianconcern.com/our-concerns/...
But if it were,so what? As long as everyone involved is a consenting adult, let them do whatever it is that works for them.
