On one hand, 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. In Bangladesh it's different because they live in the brothel, it's sort of a prison, but still there are two sides. When they think of their religion and their upbringing, they can be very moralistic. They're moralistic about giving blow jobs. On the other hand, they have an everyday life where there's no room for shame.

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.

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.

I had to first convince them [prostitutes] that I wasn't a journalist who would yet again put out a notion about them they wouldn't necessarily care for or who would victimize them. You know, journalists come and go. If they come twice, it's a lot. But I come 10 times and hang out with them and share stuff. If you connect with someone just once, that's something. But if you can connect twice, that's something else.

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."

It's interesting because the Thai king says there's no prostitution in Thailand, it doesn't exist, so the prostitutes don't pay taxes. They can work other jobs if they want and put away money, maybe leave when they're 40.
