If you are 'properly screened' by provider before she visited you for the first time,would it still be premature to give a 'hint' of what you desire?I always error on the side of caution and just wait until the visit when we both are 'comfortable' but would be nice if there was some 411 between us on what to expect.

in the event that she may NOT have reviews on this site but maybe another similar website OR No mention made about particular act which is possible,etc.

You really answered your own question. Error on the side of caution. Everyone in this biz is paranoid to a degree, and probably rightfully so. Talking about, or even "hinting" about illegal activity before she has had a session with you or before she asks "so, what do you like?" is a major etiquette breach.

Even if she may have gotten references from other known escorts about the client or confirmed background on where he works,I would think if I was the escort I still want to be 100% secure leaving nothing to chance.Neverthless,I think it's interesting to touch on the subject.

And haven't had a hooker "wig out" on me yet.

But the types of things I'm asking for are not specific sex acts either.

So FWIW if you are going to ask her if she will perform a certain type of sex act...some won't have an issue discussing post screening.  Others will.  Don't be surprised either way  

I don't want to wait till I meet her to find out if she'll play the way I want to play.  As I suspect is what you're alluding to.  There's also ways to ask about specific acts...but probably NOT in emails or texts.  I assume you know how to use a phone?

And the types of games I like are rarely...if ever in a review.

in her reviews.  If it wasn't mentioned in any of her recent reviews, then she probably doesn't do it.  If you are a fan of BBBJ and the reviews say CBJ (even if the profile says BBBJ), don't expect to be happy.  Remember, the profile is established by the first reviewer.

Of course, you can always PM several guys who have seen her and written reviews.

...Or specifics I need to know in planning his date.

Once I am comfortable that the client is who he says he is and is approaching with the right intentions I'm perfectly comfortable with him speaking freely.

I do say "please no more sensitive language that you need for me to understand" or something to that effect because I'm very good at reading in between the lines so pushing it isn't necessary.

But it is perfectly okay for you to express your preferences and needs with many providers prior to meeting- just a) ask if its okay with her before seguing right into it and b) try not to come off like you're in need of 900# style cyber sex prior to meeting.  She may mistakenly dismiss you as a timewaster.

It's one thing for experienced and veteran hobbyists to know how/when to ask about "specific sex acts" prior to meeting and which method of communication to use. It's quite another to give that advice on this board, with potentially many newbies reading this advice.

I would strongly suggest a newb doesnt mention ANY sex act with a lady until after they start playing or unless she asks him what he likes before the session begins.

Sent my partner's ATF an email with different scenarios I would like to play out.  In her defense, I was graphic.   In my partner's defense, he was shocked at the things I wrote.  This was my first experience with a provider and a quick learning experience that provider does not mean up for anything.  So my only advice, "don't ask her to suck your partners cock while you fuck her in the ass with a dildo."

That will get you shut down.

If what you want are specific sexual acts, then there's a pretty good chance she will change her mind about seeing you. I have occasionally beat-around-the-bush a little about dfk, or cbj vs bbbj, and usually got a response without losing out, but as has been stated elsewhere in this thread, I have a fair amount of experience - plus, honestly, I was prepared to lose out on the date if she did get annoyed.

On the other hand, I have had great success describing in detail the way I wanted her to dress, act on arrival, general likes and dislikes, etc. and in most cases, she appreciated very much the details that I told her so she would have a better idea of what I was looking for. Several providers have told me that most guys give no idea at all what kind of session they like and then complain afterwards when they don't get what they want. What sense does THAT make?

If a John has a thing for something out of the ordinary...it isn't likely to be in a review.  

Most of the gals I chat with have heard it all...hence no shock whatsoever.

But only after she's been able to screen the John.

There are some great stories out there. LOL

You have a tight window as far as time goes if you're doing the 1 hr bit.So with that and the $300-400 being spent,you better know what the hell you want to do.My motto is--'just get what you can out of it' so I don't suffer disappointment too severely.When I see a provider a second time,of course,I spell everything out beforehand if I want to try something newor differently.I just don't wait 5 yrs from now seeing her a second time and having to start all over as if she was new.(if she's around that long)

If a client I had never met before emailed me about something even remotely sexual- I wouldn't respond.

you'd only want to know when to be there and how long,the rest potential jail bait stuff.

that doesn't include a sex act.  I might suggest via phone or email "street clothes" so I can undress her.  "Some soapy fun" so she has an idea I want to shower together & not be upset about makeup & she might want to tie her hair back so it doesn't get fully soaked.   But we have seen each other many times.  
Even with a Fav, I would wait until we are naked between the sheets before I whispered a suggestion for a next act.  

I find a lot of first reviews state BBBJ when the gal might not routinely offer that, according to her reviews.  This is one reason why VIP to read full reviews is important.

Yep. This is how I feel about screening and talking after...if I don't already trust you by that point, I am not seeing you to begin with. When you are doing extended role play dates, it HAS to be discussed before so you can get into character, have proper attire, etc. I would feel more skidish doing this in person to he honest. I am not advocating for asking straight up, "Will you let me cum in your mouth," but there are certainly ways to get what you want across via email.

This is the most intimate of experiences for which we contract.  I have found that communication in advance is critical to a satisfying experience for both parties.  If she is not the right girl for you, she would rather let you know than disappoint you.

I have a major foot fetish and I enjoy Greek.  If I show up and she doesn't like having her feet touched and/or some gentle, respectful anal then I am disappointed and she has an average review on her hands.  And money and time are wasted.

I have NEVER, ever had a women tell me "TMI".  She would much rather know.  There is a reason I don't have any "bad" reviews that I have given, I know that we are a wonderful match before I get there.

I think once you start seeing someone repeatedly,you already established trust as to who you are so I think you can discuss sexual particulars even before meeting again as openly as you want.

I never mention any acronyms or anything graphic in my correspondence. Sometimes if I see her in a nice outfit on her website I may ask if she could wear something similar to that. Once, we are alone at the start of our date as we start to get to know each other I may make subtle mention of certain things like # cups, daty to help manage our mutual expectations.
