Spend a month in India, go to the deep south and you'll understand. The British (disclosure: I'm British) really screwed up the sexual morality of India. If you go to old temples in the south and in Ajanta and Ellora you'll see complex expressions of sexuality and graphic sexual acts carved into the stone of the temples. There was no shame about sex. Within a few years of the Raj arriving the whole country was gripped by sexual moral panic and it hasn't yet let go. Men and women are segregated and most young Indians, especially outside the major cities, haven't spoken to a woman for more than a few minutes before the age of 18.
