I’m a big fan of South Asian (Indian, Pakistani, Bengali) women, though I’ve never actually been to the region. For the best selection of South Asian women, I’d say without a doubt your best bet is London, UK. There are a ton of Indian escorts, both through agencies and as indys. Quality is all over the map but there are plenty of good ones. In a UK escort description, “Asian” tends to mean Indian or South Asian, and “Oriental” means East Asian (Thai or Chinese). Pricing is pretty reasonable, around £200-300 for an hour incall.
Toronto also has quite a few South Asian escorts, mostly through agencies. They’re usually described as “East Indian” to be differentiated from Caribbean women. Quality is also quite variable. The Indian women there have the reputation of delivering a lower service level than non-Indians, but I’ve had some decent experiences over the years. Do your research on terb.cc to increase the odds of a good outcome.
