You seem to have difficulty understanding the word, "lifestyle." Would you agree that a single lifestyle is different than a married lifestyle? Would you agree that a homosexual lifestyle is different from a heterosexual lifestyle?
One's behaviors arise from what one thinks and believes. My children have had the example of a faithful, monogamous, married lifestyle. They know that intimacy between a man and woman in the context of is a joy. My kids may giggle or make faces when they see my husband kiss me, but actually...it makes them feel very secure.
I am curious as to why you feel compelled to defend and promote a non-monogamous marriage lifestyle. I am curious as to what motivates you into attacking monogamy.
Reading this thread this morning, I had the same question. "Methinks ErickOKC protesteth too much." Maybe there's more jealousy here than is at first apparent.
