Why would someone who has a perfect marriage want to fool around?

Because some people are stupid, some don't really love the one they're with, or they don't know what love really is, and also don't respect the other person.

[Tony T]

Because their marriage really isn't as perfect as it seems. And even in perfect marriages, people sometimes get bored and look around for excitement.

Sometimes the situation just presents itself. A person has the temptation presented right before them with no effort on their part. The TV and printed tabloids are filled with examples. Sportscaster Frank Gifford was seduced by an airline stewardess who put the whole thing on video.

What is a perfect marriage, anyway? Describe it for us.
