I honestly can't imagine what would give you that impression. Aside from the triad-seeking couples posting ads, the vast majority of us married members are not like that at all. Most of us having partners outside our marriage with whom our spouses have little to no relationship.
I actually thought it was really weird the first time my husband asked if I would mind if he invited my gf over for beers one night while I was working an evening shift. I had no objection, of course. I just thought it was very odd, don't know why...
