It is only human to stare at some thing you don't see that often. May not be pleasant but to assume that her photo was being taken to be used in a pornographic sense is just, utter rubbish.
FYI: I have been stared at in the Midwest, in small town america and at times in the great epicenter of knowledge - that northeastern city called Boston. Look out for me in that next porno. Oh my.
Her imagination runs wild thereafter. I am sorry, I lived in India for 18 years and practically grew up there. I have never ever seen anyone disrespect or "jerk off" at a white person in public. Yes, they hassle you to make a quick buck or two but saying everyone chased her around the place is a wild goose chase around reality.
Sure, the media has done an amazing job of portraying India to be this sexually out of control state, and I agree it has its issues. It is only as bad as any other country in the world, really. Even the so called developed ones.
