I think you and others would find this article interesting. I have posted it before but I think it is worth posting again.
But basically it boils down to what the individual couple needs.
Savage believes monogamy is right for many couples. But he believes that our discourse about it, and about sexuality more generally, is dishonest. Some people need more than one partner, he writes, just as some people need flirting, others need to be whipped, others need lovers of both sexes. We can’t help our urges, and we should not lie to our partners about them.
Married with Infidelities
I think this is a very important statement:
Treating monogamy, rather than honesty or joy or humor, as the main indicator of a successful marriage gives people unrealistic expectations of themselves and their partners. And that, Savage says, destroys more families than it saves.
