I get told all the time "I am open to whatever you want to do" or "I want to do whatever pleases you to do to me" and frankly that is a complete load of hogwash. If I could do whatever I wanted to do to every person who comes along I would definitely be a happy Domme but it just isn't going to happen, so we need some sort of starting point from you.
I expect some kind of "I like these activities, am interested in these activities and these activities are completely off the table". Just because you tell me what you like or are interested in doesn't mean I am going to do all of them and it also doesn't mean how I do them will be exactly like everyone else does them. So much of the energy of a scene depends on you and how responsive you are...the more you show me you can take, the more likely we are to expand those limits of yours
Also, the number of pro Dommes that you have seen really doesn't mean anything to me...you could have seen hundreds, all over the world, and still be a light or medium player, so I am not going to assume anything unless you tell me and show me otherwise. Hopefully you already know your hard and soft limits and state them right up front. I have limits myself and if I find your interests and my limits butt against each other, then we won't be getting together, if I am not having fun then what is the point?
As far as GFE (and maybe I should start a new thread for this) what do you expect or want in a GFE/Kink session? Maybe requesting a "you are my girfriend and you have decided to be in control" roleplay? You might not be into roleplay, but sometimes requesting that type of scene can let the Domme know the kinds of things you are looking for, more intimate activities or more intimate language that sets a certain tone, that kind of thing. For example, when I am asked for "Mommy/son" roleplay, I know what kinds of phrases to use to set the tone, and what kinds of actions (like stroking your hair while I tell you what a good boy you are) to use that make the situation more realistic.
We Dommes are not mind readers, and I want to know what you like. If I can then combine what I like with what you like, we are golden, but if you are into things I don't care for, it isn't going to happen, so be very open with your interests when first contacting a Domme, maybe that will get you what you want.
