AU CONTRAIRE: THE OCCASIONAL NOTE FROM PETER LOFFREDO-Having an affair good for a marriage?

Is having an affair good or bad for a marriage? Our pal Pete shares his thoughts on his blog, Full Permission Living. The piece by Jenny Block is also quite interesting.
A few weeks ago, I offered my comments (read them at: http://fullpermissionliving.blogspot.com/) on whether or not having an affair was potentially "good" for a marriage.
I was responding to an article that was in the NY Times on the subject called, "An Odd Turn of Affairs." (http://women.timesonline.co.uk/tol/life_and_style/women/body_and_soul/article2882883.ece)
On the Huffington Post blog this week there was another article on the same subject, taken from Tango Magazine, entitled: "Portrait of an Open Marriage," by Jenny Block. (http://www.tangomag.com/2006130/portrait-of-an-open-marriage-2.html/1).
The piece has this caption under the title: "Jenny Block reveals an unconventional marriage arrangement that worked."
So, I took a look, because I believe that openness is the key to a good marriage, along with the two partners being fully in love with each other, of course.
On my blog (http://fullpermissionliving.blogspot.com) are some samples of what I found in Jenny's piece, interspersed with my interjections and conclusions. Check it out and offer your own comments.
