The individual least likely to cheat is the one most committed to their children or to the ideal of monogamy.
Which is why one should first be committed to the ideal (which always remains lovely) before committing to a person (who will have unlovely moments).
My point is that while men have a part in this crap-bucket, it is not all the men's fault. Women and Gays are the ones who demand sexual freedoms, not Heterosexual men. If you look to the past you will find the many "flamboyant" Women of the Thirties, Forties and Fifties that ushered in the Sexual revolution of the Sixties. Women who took the Women's Lib movement to the extreme in it's earliest stages and negated or removed the role of men. Women who "needed" no man and preferred Females. Some of the most astounding (and crack pot) sexual research and theories of these times were "found" and/or promoted by Women (including Women\Girl, Boy\Man). Remember, most of this happened in the Universities of the day first and much while the "real" men were at war (WWII, Korea and Vietnam).
