Polygamy isn't *bad* necessarily. Its when the rights of women and children are not accounted for that it is frowned upon and illegal. Or I guess should be as far as I'm concerned. Usually eeluphion is involved when peoples rights are denied.
Perhaps you are looking for a harem? Where you would be the only male? A one penis policy (OPP) situation?
It depends on what you think would be okay with you in regards to your women seeking out other lovers really. Would you be okay that or not. Would you insist on them not finding and creating other relationship? Or would you work on how that would affect you? What does your wife want and need out of all this? What's in it for her?
Lots of questions to ask for the two of you. Keep asking and talking honestly and respectfully. You've made a good first step it seems.
