Can I have an affair?

How do you feel about this assertion from a recent NY Times Magazine article?

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.

I learned about the piece from a recent Jezebel post, where a writer notes:

It seems obvious — partners should talk about their expectations for sexual exclusivity or lack thereof, and work out an arrangement that works for both (or all) of them. And yet this ridiculously simple message frequently gets lost in useless debates about what women want, what men need, what's right, what's wrong, and what's normal.

Why can't we just accept that every relationship is different and everybody should negotiate fidelity on their own terms?

I assume you have an opinion. Ready, set, share!
