The wives talk about being very offended when people assume polygamy is about sex. The Sister Wives family chose their lifestyle because of their religion, but I think there is an element of personal orientation at play here too—these are people who prefer to live in a poly-fidelity circumstance. That doesn’t mean it’s about having more sex, but that they have these commitments to multiple people (the wives also have commitments to each other, even though they are all only sexual with Kody). Kody talks in this episode about being attracted to polygamy early in life, even while he was in a religion that did not advocate it. I think it’s just part of his personal orientation, and that the wives also are attracted to the lifestyle itself.
I disagree, in this episode, when the women refer to Kody’s relationship with each of his wives as monogamous. Obviously, he is polygamous. I think they are just saying that he has individual relationships with each of them, and that he’s invested in and committed to each one. They have a commitment and they are loyal to it, so it’s not about promiscuity or casualness, or a lack of ability to be in an intimate relationship.
The Brown sister wives say that women are always asking them how they do it, and what they really seem to want to know is why anyone would want to do it! It’s true that people want to know this; that’s why I've created my site, to provide some of those answers.
