Coz just as I said before they do so as they have a stomach too.. They are not to be blamed at.. I find people pointing at them.. They are literally shunned from the society saying they are the reason behind the immorality in the society.... Wrong!!! It's not actually they but the hunger of few "MEN" which has turned this into a business.. They just serve the demand made by the men by what they have got to give.. They are not completely faulty at this.. The men of this society should change their thoughts and be satisfied by their wives and not running here and there in search of someone who could quench their thirst..
