In a first of its kind move, Amsterdam's red-light district opened its first "prostitution museum" this Thursday.
The museum hopes to lure tourists who always wondered what life was like for those on the other side of the infamous glass windows -- but were too afraid to ask.
"How do they live? What happens in their world?" said Melcher de Wind, a founder of the "Red Light Secrets Museum of Prostitution" which showcases one of the Dutch capital's most famous attractions.
"I have always wondered what really happens behind those neighbourhood windows."
Nestled between two famous brothels overlooking a canal, the new attraction seeks to offer something different to nearby museums on the subject such as the Sex Museum or the Museum of Eroticism.
"The other museums focus on sex and sexual performance. The new museum gives you a glimpse into the world of sex workers -- what it feels like to stand behind a window and the looks you get," explained Yolanda van Doeveren, who deals with prostitution for the Amsterdam municipality.
"Maybe tourists will get a chance to change their behaviour and show a little more respect," she added.
Inside the small museum, a large television screen shows a woman performing a strip-tease. Visitors are then shown a film about the other side of prostitution -- women with families living everyday lives.
There are exhibits showing how both fashions and attitudes towards the world's oldest profession have changed over the centuries.
Visitors are shown a display of the tools of the trade -- condoms, lubricants and sex toys -- based on the experiences of former prostitute Ilonka Stakelborough who advised the museum.
Prostitution in the Netherlands was legalised in 2000 and there are now around 7,000 people working in the industry in Amsterdam.
Around three-quarters of the women come from low-income countries, mainly from Eastern Europe, according to Amsterdam municipality figures.
They pay 150 euros ($202) to hire one of Amsterdam's 409 "frames", which comes with a chair in front and a bed at the back.
Many women work 11 hours a day, six days a week with a visit to a prostitute lasting around 10 minutes.
The museum depicts BDSM (bondage, domination, sado-masochism) practices, and also features a "luxury" room with mirrored ceilings, a bed lit from below, and a bathtub next to an open bottle of champagne.
By way of contrast, there is a small room with barely space for a single bed that was used by a Polish prostitute when she was not with clients.
"We want to show all aspects of prostitution," Stakelborough told AFP.
"Yes, there are women who are victims of human trafficking, but prostitution is mostly a career many women volunteer for."
