So you want to sleep with lots of Russian girls?
Here is some basic guidance.
1. Go to Petersburg. Moscow is too big, rich and unpleasant; other cities are too small.
2. If you can afford it, stay in a hotel in the center, ideally near the Ploshchad Vosstaniya end of Nevsky Prospekt. Then you will have hundreds of working girls within a 3 km radius.
3. Get a Russian SIM card with a big allowance for data (they cost little, but you have to have your passport along when buying it).
3. Install the Yandex app on your phone. That is how you will get around most of the time.
4. Go to salons. Chasing after individual girls you find online is extremely ineffective and potentially risky for several reasons.
5. If you don't speak Russian, establish a relationship with a driver who speaks English to take you around (take a few taxi rides using your Yandex app and until you find a driver who speaks some English and is willing to help). He should be willing to follow you all the way to the door of the salon. Agree with him in advance to pay him 10-20 dollars per salon he gets you into + regular taxi fees for all driving.
Everything else is red herrings.
