I wish we had of been open to this lifestyle years ago. I more than my wife was the stubborn hold out.
We had a close friend who know was open to it, but we we're too closed minded to do anything with the opportunity.
My children would have been better off with another trust worthy adult around. It would have made hospital stays, bills, and life in general easier.
It could save a lot of relationships as well. Better to add to the family than cheat. Say two childhood best friends love the same guy. He marries them both. Problem solved. No fighting or parting of ways.
I know this lifestyleisn't for everyone, but I believe it could solve a lot of relationship problems, and bring more stability to some families.
