Marriage and Monogamy

That is about as retarded as asking "Are liquids fundamental to the act of drinking?"

Nor would I ever attempt to do so. I've never met you or your wife. I'm glad you fit well.

I like your answer, especially the last paragraph,
if the sex is good sex will always be the factor, but drift away from good sex and even friendship can and sometimes will disappear,
I'm lucky, I have a great marriage and great sex, but I am allowed to have others if I want, for me it can't get any better,

I totally agree on what is written here, trust has to be total, even down to say being asked out, I should tell my husband, he tells me if or when another women hits on him, and believe it or not, many has hit on him,

Yes of course its great for marriage but wheres the fun in having only one partner? You only have 1 life, why limit yourself to 1 person?
