Men in Pakistan, why do you?.........

They itch to fix themselves too.

There is a religious twist too. All Muslim males and females who enter puberty are told to shave their groin area as a religious duty . They are also told that if they do not do so their prayers/namaz are invalid. They are also told that it is one of the basic requirements of being Muslim. So those who do not even pray one namaz on daily basis will practice shaving down there. That shaving results in an uncontrollable itch when those hair start to grow again.
