Understood.. So what you are saying is that there may or may not be something other than what may or may not be available but it depends on the phase of the moon, the mass of your wallet, whether you look left or right first as you enter the facility and if you take your pants off left or right leg first!
MM here is a suggestion. Perhaps you can start a thread called "Discretion" and under this thread list any company or girl that has specifically asked for discretionary reviews of their services.
This does not necessarily mean that every person will respect their request but I believe many would either by being more vague or by asking for more information via direct message.
Also just a question but are you sure you aren't connected to some of these places? The girls sure seem to open up to you regarding the reviews on this board..
