well.. in moscow if you want to spend time with real good girl you will pay aproximately 1000-12,000$ for hour. of course you can find girl on street for something like 90$ or almost in any pub
but when it comes to escort girls,that wouldn't be regarded as prostitutes or anything... then 4600per year is very...very small price to pay some spend more per month
