Not sure, mate. But over in Lincoln we always seem to have a steady turnover of Thais. I've got a bit addicted to them and have probably seen close to thirty now, young, older, slim, busty, vanilla, kinky etc. Love it.
When I was in Manchester I felt spoiled for choice and could barely decide on an SP. I notice that there seems to be loads of Latinas there, though? So I went through a few of them tbh.
