Reviewing my rates

I'm so frustrated by the many changes of heart I've had regarding what fees I should charge now that my situation/circumstances have changed. I recently posted an entry about increasing my rates as I was mainly touring in London (and in order to be able to provide incalls in Chester when not touring, as my expenses have risen sharply.) Now, until I decided to mess around with my rates I felt I had them pretty much at the right level
- £150 an hour incall felt neither too high nor too low, and quite reasonable when you consider I provide most services without charging extras. My outcall rates were not so lenient at £200 for the first hour - this was deliberately to discourage outcalls as I don't, myself, drive. In fact my expenses to attend outcalls normally exceeded the extra £50 I requested. Basically the way things stood I was happy with my rates and spent no time thinking whether they needed adjusting.

Now I seem to be thinking of little else. For a start: until I've reached a level I'm happy with there seems little point altering my rates on all the directories with which I've a listing. Consequently I have different prices on different websites (even my own 2 personal sites disagree on how much I expect to receive and, if I don't know myself, how on earth are my undoubtedly confused clients?!)

Basically I decided £200 an hour for an incall would be suitable for London, and cover my extra expenses so I could still offer Chester incalls, even though I didn't honestly expect to get many. (When touring outside London I was intending to charge my old rates.) However since reading through various forums I feel this is too high and I'll be missing out on meeting some lovely gentlemen should I hold them at this level. But what should I charge, bearing in mind I really don't want to start charging extras? Perhaps I should have 2 sets of rates, 1 for London and 1 for elsewhere, and simply accept only incalls of 90 minutes or more - when I'm not touring - until I have an apartment to work out of again. But then... should I charge extras, keep rates high or simply stop doing certain services? The last thing I want is to be constantly thinking about squeezing more money out of a client or how I can extend the booking, I've worked in that way in the past and it did not go well with having orgasms!
