Would you be in a Polygamous Relationship?

So I just recently saw a post of a man from Connecticut showing off his polygamy relationship with two...pretty girls of course on Facebook. It's a basically a slideshow of pics with them kissing, hugging, cooking together, all together in bed cuddling and then turns out  they both get pregnant the same time. I guess you can say they all in love?? I'm married and I can't imagine sharing my husband with another woman AND having his child. Relationships are hard as it is just with two people, imagine 3. I just want to know how many of you would actually be in a polygamy relationship and Why?! Just my curiousity....
