The reason for adultery being so common in the West and so much porn is because men have become accustomed to seeing the female body on the streets 24/7.
When these men get married their mind has already been numbed by the sight of the female body. So, seeing their wife’s body does not create the lust it is supposed to. They need something stronger. Another woman, perhaps porn.
For men in Pakistan, accidentally seeing a woman in a sleeveless kameez is like having seen heaven. So when these people get married they end up having 15 children.
These are two extremes. A society which strips women of their clothes will never succeed. And a society that thinks of its women as baby producing machines will also never succeed.
