In a broader sense this seems to afflict a lot of these "alternative" sexuality communities. "I don't feel completely masculine? Better chop my frank and beans off!", etc. People are so afraid of facing harsher realities and working through problems that they're thinking up increasingly exceptional ways to get around those problems.
I had to watch my parents go through marriage counseling at one point. And communication was one of the biggest issues between them. But they worked to improve it, and everyone's lives in our family improved. But polyamory I guess provides instant gratification and comfort for impulsive dipshits.
