The 35 Truths About Marriage--From a Guy's Point of View

The dude whose wife won't fck him, doesn't want him fcking others, and refuses to discuss it.

The foot fetishist whose wife refuses to indulge his harmless low-stakes kinks. (In that case, I'd advise him to see a professional—so long as those visits to the professional were safe, discreet, and rare.)

Long-married couples whose otherwise affectionate marriages have been sexless for more years than they care to remember. Here the rule should be: Don't do anything to threaten those marriages' socially monogamous standings.

This isn't technically about when it's okay to cheat. But I believe that the one-off, not-okay infidelity is something that an otherwise strong, healthy couple can survive. People tell me they love their spouses so much that they would do anything for them—walk through fire, give up a kidney—except take them back after an infidelity. Ridiculous.
