I've never punted many Thai girls, mostly I like somebody who I can visit again if they are good.
This being the case then i would suggest interrogating the massage shop section to see if you can find a regular shop girl whom will deliver what you may be seeking
Whilst even the shop girls may move around somewhat, you may find once you have become a regular of one that she may pass on her number, maybe swap numbers that way she can let you know where she may be next
This is something that works for me both with the Thais and the Chinese, though the Chinese are often less forthcoming than the Thais, just as an indication, i see Coco/Helen ex Rainbow quite often, we exchanged numbers quite sometime ago and she lets me know whenever she is in Yorkshire, so much so that in the past i have seen her in Selby, Wakefield and Barnsley weeks on the bounce and more recently, last week in Barnsley and this week in Wakefield
Same/similar with Jojo/Mintra, whom often works out of Ubon on york road, Chayada in the CC and more recently the new place on Ivegate Bradford
