I have found women through this hobby that seem like real sex experts to me. I would love to be able to improve my own skills by learning more from them.  Most of the time, they seem to have somewhat of a script they are following and/or are focused on finding ways to pleasure me. Not that I am complaining. It's awesome. But I would love for them to impart some of their knowledge about how men have found unique and spectacular ways to pleasure a woman who knows so much about sex. So what is the best way to ask a provider to show me something new when most of the time, my provider is new to me? (I like variety).

Want sex coaching? Pay for it.  An extended session and or multiple visits will eventually get you what you're looking for...but you'll probably find a lot of providers unable or unwilling to share before you find the ones who can open up about what really turns them on.

What I've often done is to simply say, "just tell me what you like." Then I do it.
Simple, eh?

Kgirls, and from talking to newbies that are seeking the same thing you are, and having Kgirls about these kinds of requests from customers, this is only going to work with Kgirls if you become a long-term regular with the same ones.  If you have a thirst for knowledge, you would be better off seeing an independent provider for a request like this rather than a Kgirl.  I would recommend booking two hours and tell them up front when you book that you're a newbie and have a special request.  Most would be willing to guide and instruct you on the proper way to create an explosive O for a lady.  In fact, there are several that post on this board that should probably be considered.  Not every woman responds to exactly the same things, so you may want to try three or four and get multiple perspectives.  Kudos on wanting to make yourself a better lover.  What you learn will help you with civvie women as well.

I have never had a routine, but hear many ladies do. I provide consultations. As a professional I have always offered consulting. Pleasing everyone is very different. We all have separate things that arose us. Learning how it’s best to ask the provider your attempting to please.

The key is to ask. Do it elegantly, and sensually, like you're writing a poem, but do ask.  
No two broads are the same, because orgasms for them are as much of a head game for them as they are actual stimulation. Talking with them about what they want you to do to them in spicy specifics makes for great in-person foreplay.

 
If you're just thinking that you can get a crib sheet on "how to please woman", you're a caveman, stop it, it doesn't exist, never has, never will.

 
In terms of the hired help, they're only going to be useful if you're looking to get dudes off. No judgement here if that's your goal, go get'em killer, you're barking up the right tree. Most of them aren't going to orgasm with a client. The ones that say they do are lying. The guys that claim they made it happen are either lying or they bought a lie, not sure what's more pathetic but I lean towards the former. Sometimes you get a lightening strike, good chemistry, stars align, and it happens, but don't be fooled into thinking you're some sort of sex god, you're not, you're a paycheck, don't forget it and don't let it ruin it. Believe the lie, don't fall victim to the lie.

 
if getting broads off is what gets you off, find yourself a sugar baby, talk to her, and make a woman out of her. I get the appeal, I subscribe to that model even, it's good fun. Most of them are jaded AF by the time you spend time with them, and un-jading them is doing the world a service in my book. If you do it right, you'll get booty called, because they'll know where the good dick is, and you'll know that it's not your dick that's spectacular, it's knowing where their buttons are, and how to press them. EOM

When with a new lady and at the start of foreplay, I often state that I take direction easily, or well, or whatever.  Point being I am signaling that I am willing to adjust based on her likes, and dislikes.  

Sometimes I wait until right before DATY.  

Some take me up on the offer, others don't.  When I repeat a visit, I make the statement again and THEN I usually get a more candid response, but  not always.

One time I visited a pro stripper who also escorted.   She told me flat our not to focus on pleasuring her, as she will not orgasm.  Rather the focus was to be on my pleasure.  One of the most erotic sessions I have ever had.

Good luck!
