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.
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.

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!
