Pray for Monogamy

"He must not take many wives, or his heart will be led astray" (Deuteronomy 17:17) Monogamy or natural polyamorous identity? Nature or upbringing? Is monogamy purer, more moral or loving? What it would be like to wake up in an idealistic world of monogamous people? Will I feel safe knowing that my partner can only be with me and I will never have to face his emotional or physical attraction to someone else?
