Time and time again the subject of sex and jealousy is raised in discussions about our lifestyle, in this article from his Blog, Polyamory Paradigm gives us his view on the subject:

Recently I was talking with a partner of mine about her potential new lover who is a contradiction to her normal tastes and desires. Being a bit confused, I asked some questions to which I got a response that surprised me. Referring to her potential new partner she said, "We are poly. You know I'm going to sleep with other people so I didn't think you would care."That got me to thinking about conversations I've had with potential new partners of my own. One of my relationship rules is that I know about any new sexual partners they acquire before we have sex together again. Let me be clear with that one. It isn't that I must know before they have sex with a new partner (though that is my preference), I want to know they have had sex with a new partner before I have sex with them again so I can gauge my feelings about safety. Often the response I get to that rule is much like the one my current partner gave; "You're poly. Why would you care if I sleep with someone else?"

My own personal views on monogamy are that it is a moral-social construct originally created and sanctioned by the church and later by capitalism.

I have studied the human arousal response and come to the conclusion humans are designed by nature to not only have multiple partners, but have them at the same time.

The male arousal response is quick thus enabling him to release his sperm and move onto the next woman quickly, ensuring him the opportunity to spread his genes around to the widest number of women.

The female arousal response is slow in comparison, ensuring she is not quickly satisfied, thus she will be able to have many partners in the one session to ensure she has the best possible opportunity to get the strongest genes for her offspring.

This is natures way of guaranteeing diversity of the species and trying to remove any "weaknesses" such as inheritable diseases( Dementia, Parkinson's, Huntington's, etc).   Physiological markers of race could be said to be inherited weaknesses that become more pronounced over generations.
