It could be she means be direct about how long you want to spend with her, it's hard to say, that's a vague question.  Generally it's a big no-no to be direct about discussing specific things.  

You definitely don't want to be discussing those activities for which no compensation or other thing of value is exchanged for; at least not until you know each other.

I don't recall seeing an ad like that. Directness about the transaction she is advertising is the last thing a provider should want. Unless she has been plagued by hagglers and time wasters, and it's a poorly worded request for "serious inquiries only". Or unless she's a cop.

I bet she means:

Read over her website and make sure she is the one you want to see based on her rules, rates, pics, and screening requirements et cetera.


Submit your screening info and/or make contact and politely introduce yourself.
Once you've passed screening, schedule an appointment and follow her lead from there.

I am thinking she is trying to weed out time wasters who just want to talk on the phone while they jack off or go on for months with endless emails and texts but never booking.  I think she means don't waste her time and schedule an appointment!

Maybe?
