So, as a record of what I'm potentially intending to explore while I'm in Amsterdam.. I may try one of the follow:
Dam Square Babes -
http://www.damsquarebabes.com/ - The name sounds so typical touristy .. I feel pretty skeptical, can't find any general reviews anywhere, but they have a twitter account and a single review on TER (
https://www.theeroticreview.com) so seems somewhat legit?
Roksolana -
http://roksolana.nl/ - Haven't heard this agency mentioned anywhere but saw some reviews on Hookers.nl & Kinky.nl and they seem pretty legitimate and impressive. Ads hosted in the forums as well and they seem active in responding to reviews. Curious.
