There was a better than evens chance this would tun into a price thread.

I agree £150/h is "steep" - but there are lots of threads here on miserable punts at £60 for less than 30 minutes (and I have had a few of these myself).
I was curious if the whole "Tantric" thing is more intimate and worth 3 trips to Orchid Thai.
The sudden volume of Tantra providers seems strange - and £150 on a miserable punt is a lot worse than £60
If I get lucky in the bookies I'll write a review
