Definitely concur on Europe: it's very expensive by SE Asia mongering standards. I also think there are more rip-offs lurking in the European theatre of operations. The only time I was truly scammed was in London. Forget about France unless you want a tranny in the Bois de Bologne kind of experience!
O.K, o.k., they do have services in France, but you should mostly forget about those too! Scandinavia? No service needed! Just be tall . . .
Germany has things well codified with the FKKs, after hours dating is still highly variable. Eastern Europe is productive but lots of gold diggers (if that means anything in a P4P context) if you go for the equivalent of extended LT/dating.
U.S. imports lots of Asia talent (particularly San Francisco and the West Coast) so the whole 'off-the-clock (never truly)' is common there with the AMP and TAMP girls. No barfine to pay but the common etiquette is the proverbial shopping trip(s), in some ways it feels more like going with a karaoke girl, but with sex (if that makes any sense). I've had TAMP girlfriends that lasted years with no shopping trips at all and then working girlfriends who would get right to the point (and so didn't last long with me).
Singapore and the semi-pro scene there is kind of a hybrid: fairly well-defined, extended time boundaries (she'll stay all night) with a fairly well-defined cost. She'll proposition you in the bar if you make eye contact. It's a pretty easy game, although I mostly find my errors to be ones relating to not being able to see in a dark bar!
Man they sure look different in the light of day!
I haven't played much in the P4P arena there, even though it is excellent and extensive, simply because the semi and non-pro opportunities are so huge.
Vietnam is a somewhat confused scene, everything from 'me love you long-time' schtick in one of the numbered bars of District 1 (where you can even get a BBBJ under the pool table), to ST/LT back at your hotel to semi-pros picking you up on the street or from their scooter (nothing cuter than a girl on an antique Vespa giving you the twice over
) to 'semi-pros' (using the term loosly here) at AP picking you up for the night (price frequently not negotiated at all, just left to your discretion). Have to know which hotels are 'GF' and which aren't. P4P is illegal here but tolerated if it's not out in the open. You can get excellent BBBJ services from some hotel massage staffs (but not all so be careful who you ask!) and from even the hair salons (but again some, not all). Tread carefully!
Hong Kong is new to me, so very little to write about outside of 141-land. Seems like a lot of fun here and I'm looking forward to learning more.
