in [link|http://z.iwethey.org/forums/render/content/show?contentid=135775|http://z.iwethey.org...?contentid=135775] where you say, Marriage should not be primarily about humping, and indeed in a better society, people could allow themselves to maintain a stable family while obtaining their humpage elsewhere, should it be necessary.
If a married couple is "obtaining their humpage elsewhere", then that is marital infidelity in most people's books.
