"Men cheat for the same reason that dogs lick their balls... because they can"

This quote by Kim Cattrall is a funny way of explaining that guys frequently cheat because they can get away with it. It suggests that males are not always driven by a need to cheat, however rather that they are making the most of a situation in which they can do so without consequence. The comparison to pet dogs licking their balls is implied to be amusing, but it also serves to highlight the concept that males are not always driven by a requirement to cheat, however rather that they are making the most of a circumstance in which they can do so without consequence. This quote is a pointer that guys must be held responsible for their actions which unfaithful should not be endured. It likewise works as a suggestion that guys should be aware of the effects of their actions which they ought to hesitate before engaging in any behavior that might be considered unfaithful.
