This is not a new subject nor is it one that is in any way surprising given the number of 'discreet' relationships I have been witness to that are, in reality, anything but, While I am the last one in the world to preach on this subject, the story in the attached link is just one more thing that you need to account for in keeping that hidden little secret just that.
With the proliferation of security inspired cameras all over the place in both public and private spaces, the chance of exposure for those trying to maintain a clandestine relationship becomes increasingly more likely. Before venturing out of the deep woods keep that in mind and enjoy the attached article.
As a firm believer in the tenet that the human animal, such as we are, is not - nor was ever - geneteically predisposed to be monogamous, I am nevertheless a proponent of responsible non-monogamy as opposed to gratuitous, anonymous sexual encounters. While each may have its place, the former allows for the development of stronger and more vibrant relationship between partners who are on the same or similar pages when they embark on this journey.
As the host of a group that currently has 3000 sexually explorative member couples, I have been witness to most everything, bad and good, that might present itself in situations of this sort. I have seen couples blossom by coming out and opening themselves up to sexual exploration with others. Generally, these are couples with already strong bonds that are looking to expand their horizons by including others in their sex play - be they one time encounters or ongoing intimate relationships.
I see some comments suggesting polyamory as an "ideal" that should be taught instead of monogamy. One of the dangers of "millenarian" thinking is the notion that some new "ism" will be "the answer" for all our problems. Whether Communism, Free Love, Scientology or now polyamory, the same promises of a universal answer to our problems deludes us into thinking we can tell the world how they should live.
People, let's be grown up about this and stop thinking for our fellow men and women. Monogamy works fine for millions of people around the world. It's like saying "I have a peanut allergy so let's ban peanuts." If monogamy doesn't work for you (and it doesn't for me), fine, but don't try to raise up polyamory (with its many problems and issues) as a false answer.
I was reading Doonesbury yesterday and the cartoon pointed out the hypocrisy of certain Republican candidates for the presidential nomination. Between three of the leading Republican candidates, there are five divorces, "four really messy and all involving adultery."
