This extended look at the current state of monogamy in committed relationships has some very interesting talking points; I suspect the content would be especially valuable for folks raised in a conservative / religious household.
In my own experience I feel that my church failed me passively, in so many ways, in terms of preparation for healthy adult relationships, and actively in terms of a church-approved sexual relationship.
Further, I think you can read the article and replace "sex" with any number of other subjects and find it relevant...part of my core NTTATS philosophizing is concerned with the fundamental disconnect between two people's conceptualization of any idea, and the challenge to any long term relationship is finding a way to manage that disconnect. Some people (on some issues) prefer to pretend that there is no disconnect; in other cases it seems that any relevant conversation requires a reiteration of the manifold ways the two parties disagree.
I'm a believer in committed, long term relationships (romantic, friendly, family, etc) and so I constantly strive to keep the NTTATS cynicism in check, and I find discussions like those in today's article provide a helpful framework for that anti-cynical work.
