Here is my attempt to add some info for those planning a trip to Amsterdam. First let me say it is a very fun city and you really need to experience it for yourself to appreciate it. I've been three times now, and I must say I enjoy their liberal attitude on many subjects. Here we will focus on sex though, no time to discuss the other pleasure of Amsterdam.
The Amsterdam scene has something for everyone, not just the window girls in the RLD (red light district). Keep this in mind. There are window girls of all shapes, sizes, colors, and ages I assure you. The variety is mind boggling. But, there are also incall, outcall, independents, agencies, street walkers. brothels, swing clubs, massage parlours, live sex shows, you name it and they got it. Well with the exception of what we Americans and Canadians think of as a strip club, I haven't found something comparable to that yet.
RLD:
Most importantly there are 3 different RLD's in Amsterdam proper.
Most tourist only know about/go to the largest main one. It is called the "Wallen" and it is nearest to the Central train station.
The 2 others are "Singel" and "Pijp" and they are a bit farther out, but certainly "Singel" is walkable from the main "Wallen".
There are plenty of gems to be found in the Wallen, but remember tourists get screwed everywhere, even though there are more girls your overall odds of good service are lower there.
In the Wallen it starts at 50euro for 15min, elsewhere most will qoute 35-40euro for the same. If you want more time which I usaully do, you can bargain for much better prices if you start with those numbers.
Most window girls are very safety concious, I think because the Dutch government drills it into their heads. Even if you have money to pay many will refuse, BBBJ DATY digits etc.
The girls rent their own window and like any realestate the price varies based on location/size etc. Girls on the main streets with the biggest windows are not neccesarily the best performers, they are actually probably the most likely to upsell in my opinion. Try the girls on the side streets less traveled.
Some girls tend to move around alot, meaning even if you have somewhat recent info the girl may no longer be in the same spot. Also, some girls sublet their windows a few days a week or for "shifts" of the day. Make sure you have a decent description of the girl you are looking for not just her last know location.
*** One very important thing I have learned though from my trips, look for girls that have something unique hanging in their window. Like a little toy you would stick to a window in your car or a sticker or a stuffed animal. Girls use these so their repeat clients or those who have recieved "recomendations" can easily identify them. It works well and if a girl is expecting this type of interest she probably really does provide top notch service. Also, just like a strip club booths, windows that are busy a lot could mean very good service, especially in the less traveled RLDs.
**** Never show a window girl a big stack of money. You will immediately be upsold, always show less than 50euros more than you plan to spend, if it all.
*****If a girl immediatley tries to upsell you once you get in the booth and hand over 50euro, a common tactic, ask for your money back as some will. Under no circumstances give her more money, loosing 50euros sucks but service will definetly not improve much, cut your loses go elsewhere.
******Just like anything else repeat business can improve service. If you find a girl you like, give her a second shot.
******* Everything in the RLD is on closed circuit video, I mean absolutley everything. If you get out of line, security will appear out of no where in literally seconds. Keep this in mind I've seen it happen several times.
******** Lastly I have been told by many different girls that, approximately 50% of all men who visit the windows are too drunk to even get it up. They pay the money and pretty much leave frustrated. I did not have such problems, quite the opposite, but I'm sure it is very frustrating for both parties. Keep this in mind also.
Personally, I love the eye candy in the RLD, window shopping in the truest sense. But, for my dollar I prefer the brothels or "prives" as they are called in Amsterdam. My favorite is Park 118, google it it if you want more info, but usually they 8 to 10 girls to choose from and for 120euro you can have a full hour with everything on the menu, in a real room with a real bed. Also, it soo much more discreet than the RLD. Prives can be very hard to find, they just look like regular houses. They usually have no sign, maybe a tiny credit card logo somewhere near the door (they all take plastic, cause it's totally legal.) You just have to go up and ring the doorbell (make sure you have the correct address or else it could be pretty embarassing.)
