Many Indian men grow up having very little contact with women outside their family, cross-cultural and management consultant Rajeshwar Balasundaram wrote in an email.
When they meet foreign women, they rely on the stereotypes they have acquired through Hollywood and Bollywood movies of foreign women as free and loose.
These men think they can communicate freely with these foreign women, but sometimes they get carried away.
“They think the Western woman is fair game,” says Times of India columnist Bachi Karkaria.
A foreigner might be trying to make friends, but if she gives a man her phone number, he assumes she wants to take the relationship further, Karkaria says.
In places like Mumbai, she says, there is often no understanding where the line is drawn and people freely mock those with less power.
At workplaces, for example, some employees send around mass emails blatantly making fun of women and lower caste people, she says.
As Mumbai changes and modernizes, there is confusion over what type of behavior is acceptable in personal as well as work environments, says Jerry Pinto, author of "Surviving Women," a manual of gender politics in India.
“We are going through a period in which no one is quite sure what the rules are,” he says.
Some foreign women here consider the behavior, which can be characterized as an extreme amount of one-sided communication, as innocent flirting.
Others find the barrage of messages and phone calls to be nothing short of harassment or even virtual stalking.
Rough sex is surely an acquired taste, and most ladies even pretend they are not particularly into it.
