Most of the well fed, well brought up, good looking Indian women will never do porn. They'll die before that, chiefly because of their concerns of what will happen when their parents find out. The ultimatge aim of most Indian women nowadays is to get a top job in some huge firm, or find a husband who's got such a job. A pornographic past in a huge no-no in both cases. Plus, most Indian women are kind of prudish and shy, be it US settled or in India. I've heard they'll do a lot behind closed doors in the bedroom where no one else will see them, but they'll never do those things in public.
Hence why you mostly find the shitty looking hookers off the streets in Indian porn. Some US settled Indian women, who are halfway decent, will do porn but they are few and far in between.
