I have been to both the London Enema clnic and raibow health spa, London Enema clinic is by far the best and one of the best anywhere.
Rainbow is not bad, there is a lady provider, her name is Joeb she is also in London and is very good. She runs an add in the UK Forum magazine.
I know of others outside of london who are also very good
In California there is a nurse called Ava who advertises that she is a very experienced enema provider. Also in orange county there is a provider who goes by the name of Victoria, all these can be found on the Max Fish dominant guide.
I have tried the London enema clinic as well as the Rainbow health clinic and Joeb.
London enema clinic and Joeb are very good there is one other place that is very good, that is the colonic clinic in Cornwall she is also very good but very expensive.
