I get a lot of people coming to this site by searching the terms “prostitutes in Hanoi” or “prostitutes in Bangkok”. I have no problems with this, though I do feel bad that I don’t provide that kind of information. In order to reach out to those on a search, and to feel useful, here’s what I got for ya:
As for where to get pros in Bangkok, I’m sure there are far better sites than this. Better yet, just walk down the street or tell your cabbie you wanna go to Soi Cowboy or PhatPong.
Hanoi is another issue. Prostitution is alive and well, though much better hidden than in Thailand. Good bets are karaoke bars (behind the train station is a gold mine I’ve heard), dark corners of busy streets (usually women or their pimps on motorcycles) and bars like New Century. I don’t know what they cost or what they’re like, but there you go.
