As someone who is from the South Wales area and who is now working in London, I'll say this; You're in the best location in the UK by far. I'll also say that there are far more convincing independents here to choose from than in smaller towns and cities and you're far less likely to come across coerced or pimped girls (although they do very much exist-it's all in the numbers). Cardiff by comparison is pathetic as it centers around one or two 'shops', and the locations of these places changes every few months with the regulars being notified by group txt. There are on occasion a few EE flats but they're few and far between and a little dodgy. I've spoken out about these places being full of pimped and trafficked women but nobody seems to care. It's a true reflection of the local economy.
Here in London the standards appearance-wise are much higher, the service is significantly higher providing you use common sense/research and the prices are reasonable if not competitive. Doughy bodied British women find it difficult to compete in this market because their service is 'usually' sub-par and they're simply not lookers, especially for the money. That's why the really hot Brits can charge more as they're few and far between and visiting business clientele seek these girls out for the 'British' experience.
On a personal level, since I've been here I've received far more attention from women than I ever did in Wales. Your average bloke can 'pull' an exceptional looking lady here whereas elsewhere it's well turned out guys dating ropey looking, laddish girls!
God I love London. Roll on summer!
