who would you choose?
In all honesty, if all three were £100 per hour. I still wouldn't book any. At £200 an hour its insane. Their photos they have on each profile are very poor and unappealing.
There must be better girls where you are based?
The best advise is to start a blank "who should I see" topic in the section of the forum for the region you are based and get advise. As opposed to which one of these three as you have done now.
