Cheating in relationship is a sign of self-regulation failure. When it happens ones, it is a mistake. When it happens twice, it is unfortunate. But when it happens thrice or more, it is a pattern indicating primitive, uncivilized inhuman behavior.

Monogamy is not a choice, it is a responsibility of a genuine human.

Either one is promiscuous or in a relationship - it cannot be both at the same time.

Polygamy is a luxury of the cave-people, and monogamy is an existential responsibility of the civilized society.

Polygamy is about sex, whereas monogamy is about love.

Promoting promiscuity in this evolved and civilized society is actually like signing the Declaration, that says:“I hereby renounce my membership of humankind, since I am neither human nor kind. I declare that I no longer belong to the modern human species, i.e. the Homo sapiens. From now on I shall be counted among the swingers of the animal kingdom, such as the bonobo or montane vole. I am simply an arrogant philandering savage.

Philanderers and swingers can see nothing beyond the needs of their genitals. Sexual craving is a part of our biology, but it is not who we are.
