5. Polygamy
Are you bored of jealous Sims smacking each of your other love interests? Wish that your sister-wives could just get along? Want more kids than Bob Marley and make sure everyone's okay with it? This mod is just for you. With the polygamy mod, your Sims are now able to have a relationship with -and marry - more than one person at a time. You can go the Hugh Hefner route and date multiple hot blondes or, if you prefer, you can even enter a group marriage - let your freak flag fly! All without that pesky jealousy getting in the way. You can download polygamy mods at All Sims Mods and Mod The Sims.

Polygamy In The Sims 4
I am searching for a mod that lets you marry more than one spouse for sims 4. I seem to be having trouble finding it and you know how it goes with the damn google search it sees sims and then ignores the number put after it and so I get nothing but everything related to sims but not sims 4. Sims 4 The one big mod that always shows up is Inteen, but I only want the Polygamy part of the mod, not teen pregnancy or incest. Are there any stand alone poly mods?
