So, when I show up, the first question I'm asked is, "Well, what do you want to do?"  Early on, this was kind of a stumper, because I assumed the lady knew what I wanted to do.  It was all vanilla.  But I realize now that I want the woman to be very aggressive.  Not BDSM aggressive, but horny, I-haven't-seen-you-in-three-months aggressive.  Do you know what I mean & how do you ask for this?

You ask for the Double Double, that's GFE. Now if you want to spruce it up, then you ask for the Double Double, Animal Style., now you're really talking...same correlation. Easy peasy.

But some gals just aren't that way, so don't be disappointed if she demurs.

 
I kind of like that approach myself.
There was a gal that greeted me by knocking me to the floor and tearing my clothes off - and the hotel door was still open!  I had to kick it closed and then we resumed.

I too am asked that question all the time and here is how I answer.

I pull her very close to me, give her a deep passionate kiss and say "THIS" is what I want to do. and then 99% of the time it's off to the races.

I think you are probably like me in one regard. I do NOT need "time to warm up" I usually have an erection before the door even opens and I don't need a lot of chit chat to "get in the mood" I am ready the minute I lay eyes on her if she's hot. So rather than beat around the bush about what I want to do, I simply start doing it. lol

...it's best to live in the west.

...so when I contact a provider I will sometimes ask her if she's more sexually a sub or a dom while we are still setting up the date, and I let her know what I prefer. That way she knows going in what I like and she can pounce on me when the door opens

It should be very obvious if she's sexually aggressive. Tell them you like a balls to walls type session.
