Thanks Crystal for a well-written article. We humans can thank nature for sticking us in the worst of all situations, sexually speaking. Our physiognomy and our behaviors both signal we're a semi-monogamous species doomed to struggle with monogamy yet unequipped for the sexual freedom Bonobos use to form and sustain social bonds. While few people will have the emotional maturity for a successful relationship of any kind, those lucky few who are kind, generous, patient, and open-minded can discover that some forms of non-monogamy provide a satisfactory solution to our biological conundrum.
