Sneaky use of the modifier "some."
You are, in fact, talking about the top 10% of men. The "top performers." The smooth-talking alphas.
No one here is defending them or their profligate behavior.
"Ordinary joes" would have to undertake herculean efforts to "cheat," undetected by their spouses, on a regular basis (or they have incredibly low standards and will resort to bedding the lowest forms of life lurking around on a tavern floor).

The wife would probably notice the withdrawals from the checking for a paid escort, which is about the only way an average guy could cheat.
