La Zona is such a closed area, a dangerous, outlaw area. My time in the Zona was a time outside of society, almost out of the real world. And the girls there had such a sense of irony and sarcasm. They were also really interested in my film. They'd be like, "Thank God we live in Mexico, because our kind of prostitution has a heart. We wouldn't want to sit behind a glass cage or be sold by our own mothers. We have free will."

A young man in Bangladesh can't even hold hands with a young woman. Without marriage there is no kissing, no holding hands, no going anywhere. So young boys can only go to the brothels for sex before marriage.

Mostly I take photographs in times of research. Whores' Glory was shot in 30 days, 10 days for each segment, but the research for each part lasted a couple of months.

Sometimes the presence of a camera is like opening a door, because many people want what Andy Warhol called "15 minutes of fame." But prostitutes don't want that.

In Bangladesh a prostitute normally wouldn't even undress for a man. He pays, she pulls up her sari, and he's done in 20 seconds.

Whenever a man enters the realm of prostitutes he's always regarded as a possible customer. If you enter as a woman, you're regarded as somebody who could be in the same place. Being a man brings the perspective of flirtation.

On one hand, they [prostitutes] don't struggle because it's simply their life. In Mexico and elsewhere, once they get out of these places [brothels] they have a pretty square life.
