Sex in the RLD is the most joyless, passion-free experience I have ever had.

Try the Prive clubs or sex clubs. You have to be careful here too as some are scams or seriously expensive. Read the reviews and choose carefully. The last time I visited, my favorite was Societé Anonyme. I went thee three times over the course of a week, and I had a great time with each visit.

Just google "amsterdam club prive" and try the first few links.

The RLD is a great place to find providers providing you do your research. One advantage to the window girls , pre booking is not necessary.

 If you interview and decide not to see her, she won't cuss you out.

 Find a seat at the Red Light Bar.

Look outside and notice the  individual large  windows and doors with hookers inside.
Take note at the customers arriving and the amount of minutes until they leave.  

  That's entertainment in itself.

If you paid attention you noticed some window Ho's took much longer with their customers.

 Those are the Ho's you want to interview.
 
Three steps to Red Light Success

1. Knock on window of your choice.
 Some of the window girls are particular who they will see. If she doesn't answer, or looks the other way, move on .
 

2. Ask her how much and the amount of time.  
 
 If she tells you 100 Euros and 15 minutes ,she will rush you out the door.
  If she tells you 40 Euros and time limit is whatever it takes, she likes you and  there is no time limit.

3. Look into her eyes for the passion sign.YMMV

Decide.


Remember not to knock on any  blue windows unless you are looking for women who are women only from the waist up.

Spend some time walking around the RLD before you make your choice.  The girls range from aging trolls to stunning "10's." Also, most of the girls will charge 60 Euros for sex, and charge for each additional service - 60 Euros for a BJ (usually covered, but some will do it uncovered), 60 Euros for extra positions, etc.  Some may even charge 60 Euros to take all their clothes off.  Still a good deal if the girl is hot enough.  You need to shop around.  I've seen 3 girls in the windows and their performances ranged from mediocre to GFE.  Seems if you go during the day or morning you have a chance at a newbie who has not yet been jaded and has not yet realized that girls tend to charge ala carte for each service.  Indeed my best session was with a Bulgarian newbie in the morning before I left for the airport to get my flight back to JFK.  Good luck.
