why man mostly has an affair with ugly woman?

Why man mostly has an affair with ugly woman? And my another question is why mostly man who has beautiful or sexy or famous wife, always has an affair? This are my questions which I do not get any answer until now :D The second question, the answer may be because the woman is busy with herself, so she forget to take care about her man. You know, sometimes man like a child, he needs attention more than any body else. LOL

So let us check a few cases about famous married guys who have an affair :

1. Prince Charles

In my opinion (and I thought in many people in this world), Prince Charles ex wife : Lady Diana is very beautiful woman. Beside beautiful Princes Diana is very kind woman and humble too. But he had an affair with Camila who is more ugly and older than Lady Diana. For me it is so awful, why he did not get others beautiful and young woman which was easy to get because he is a Prince :D Why must be with Camila ???

2. Hugh Grant

Hugh Grant had an affair with one hooker name Divine Brown when he was together with Elizabeth Hurley. Can you imagine? Elizabeth Hurley is so beautiful and famous, could not compare with just no body name Divine Brown. And why Hugh Grant should have an affair with her if he could get any beautiful actress or famous woman? Uh!!!!

3. Eric Benet

Eric Benet is Halle Berry ex husband. When they were together, Eric Benet had many affairs with many women. Can you imagine? Why he did not feel sacrifice to have very beautiful woman in this world like Halle Berry? Why did he still need others women in his life?

4.Bill Clinton

This was ever be a scandalize story when Bill Clinton had an affair with Monica Lewinsky who is fat and more ugly if compare with Hillary Clinton. They both can not be compared. Exclude the ages, Hillary Clinton is more in everything than Monica Lewinsky. So, why Bill Clinton did have an affair with her? Too lonely? :D

5.Arnold Schwarzegger

This is the new scandalize story lately. How could he has an affair with his maid who can not compare with his wife Maria Shiver? I do not understand why he did this stupid things. Where was her brain when he did it? Uhm....

And there is many others stories about kind of affair. And all are same stories :D

Of course it is not my problem, I just want to know the reason, why they choose women who are not comparable with their partner? Why not with woman who are more beautiful, more famous, richer ?

Uhm .... really hope one day, there is a man who can explain why this phenomenon happen, so I can more understand it with my logical thinking :D
