Just got back from a vacation to Amsterdam, and I know you all want to know the scoop. So....
On average, I'd say that the breast sizes on display in the Red Light District were very close to the actual average for women. My eyes wanted to see them as bigger than they really were, naturally. But I can only claim to have seen a pair (obviously fake) of F's, and one or two women with E's. The rest were normal B through D.
Now, if you're going there.....
As my tour guide informed us, 50 Euros is the basic "entry fee" - it gets you 15 minutes which works out to a quick blowjob. 100 Euros gets you half an hour, and can lead to something more than just that. All special requests are negotiable (if you can afford it), but the woman has the right to refuse service to any client. And the rooms are all equipped with panic buttons if things get nasty. Oh, condoms are MANDATORY, all the ladies speak English (Note: I NEVER had language difficulties while I was there), and it's pretty much a CASH ONLY business as you'd expect.
No, I don't have photographs. There are little signs all over the place reminding you that it's forbidden. And if you're lucky when you try it, you just
might be able to fish your camera/phone out of the canal....
The "storefronts" are usually all windowed doors with red florescent lights over them. Dark red curtains close over the windows when the spot is closed (or the woman is busy). The actual space is a bit bigger than a walk-in closet. There's a chair or stool for the woman to relax and check her phone when she's not showing off for passers-by. The bedroom is in the back. Windows tend to come in clusters, suggesting that they all share a common suite of "bedrooms". Many of them are located in alleys, so don't hesitate to at least peek down them. Please note - these alleys can be VERY narrow. We're talking barely enough room for two people to pass by each other.
There are also a LOT of bars and "coffee shops" in the area, which means that there's going to be quite a few louts (drunks, mostly) wandering around. Try to avoid them as best you can.
While some "windows" are active during the day, those are very few. It's only around 8 pm when the "night shift" begins that things really pick up.
By the way, there's a smaller collection of red lit windows on the other side of the Damrak, just south of the Lutheran church.....
More fun info:
There's a union for sex workers there: PROUD
http://wijzijnproud.nl/en_GB/All of the women are required to be licensed by the government. About half of their income goes to taxes, but even after rent is subtracted (they have to rent the "window", almost always from an agent who rents the houses), it's still possible to make a acceptable living doing it.
Despite all the business that goes on there, the Red Light District is primarily a residential area. It's actually a nice place to stroll around when the crowds aren't too oppressive - if your feet can handle the fact that virtually all the sidewalks (and many of the streets) in the area are paved with brick or stones.....
