There is a particular local duo combo that I want to try, but I'm having a communication problem and want to make sure that I avoid a breach of etiquette. Each woman in the duo has another provider that they do duos with more often, but they have also worked with each other quite a few times.

 
Provider A is my current favorite, and I'm one of her regulars. When I last saw her, I expressed interest in this duo, and she was up for it. In fact, talking about it made her wet. However, she insisted that she wanted to be the one to coordinate the appointment, because the other provider was late the last three times that they worked together. Just in case there was an issue, I asked if there was anybody else she would rather do the duo with, and she said no. She mentioned a couple of other providers that she was interested in, but admitted that she hadn't worked with either of them before. A is the younger and less experienced of the two, and has only had one other duo partner.

 
I saw provider B for the first time last month, and we got along fine. I mentioned the idea of the duo to her, and she was interested. Based on her past duo reviews, B has a favorite type, and A is definitely it. B had more than a decade worth of reviews here, including more than a dozen duo partners, and was ranked in the national top 100 as recently as April. She uses a scheduler, but I did have some communication problems with her and her scheduler the first time I tried to book with her.

 
I actually tried to book this same duo last year, through A. A asked if I had seen B before, and I admitted that I hadn't. Several days went by without any communication, so I asked A if we were on for Sunday, and A said "it wasn't going to happen." I asked for clarification, and A got really irritated, so I dropped the topic.

 
It has been a week since I emailed my duo request to A, and still no response. I did notice last week on P411 that A hadn't logged in there since June, but when I checked again a couple of days ago (getting worried that she had retired), she had recently logged in. So I emailed my request again yesterday, "just in case" she didn't get the original request. Still no response. Whenever I have booked with A in the past (not counting the previous duo request), she has always responded within 48 hours. So I'm thinking about waiting another day, and then contacting B to request the duo. But maybe I should try other methods with A first, like a PM thru P411 or a text or even a phone call. I don't want to piss A off again, but I do want to make this duo happen.

Actually, it's not that simple because the way you describe the timing isn't clear.  But this is what it sounds like:
1)  You saw girl A and told her your plan.  You told her you hadn't seen B  but agreed to let A take charge.
2) Then you saw B but didn't tell A.
3) When A got in touch with B she found out you'd seen her and she now thinks you lied.
4) Then you made matters worse by badgering A. Twice.
If the above is correct and you don't see how you fucked up, find another sport.
Or correct us and clarify.

between the two girls that is more than just a scheduling conflict.  When you asked a year ago for the same duo, and she got "irritated" when you questioned her about why she couldn't get it set up for that Sunday.  If it was possible to pick another date, she would have told you, but instead, bluntly told you "it wasn't going to happen" and didn't want to discuss it any further.  If it was just an available issue, she would have told you that the date is bad for the other girl and you will have to find a new date where you are all three available.  Sometimes, you have to pay attention not only to what they say, but HOW they phrase it.  I would have known from your recollection of the event last year NOT to ask for this duo again, but you did, and I would say THAT is probably why you didn't get a response.  She probably thinks you're a little dense.  Add this to +1 on the sub-points Jake made above.  

Some clarifications, following your numbering:

1. I saw A in May. I also mentioned that I had tried to see B in May, but miscommunication between B and her scheduler resulted in B canceling me at the last minute. A wanted to do the duo, but recommended that I try again to see B first.
2. I saw B, and I told A in my email last week when I requested the duo appointment.
3. No idea if A has talked to B yet, or even read my two emails.
4. Is it badgering? I sent the first email to A on Thursday, July 12th. I sent a follow-up email to A on Wednesday, July 18th. I haven't made any other attempt to contact A, and I haven't contacted B at all. I am asking advice here on how to follow up in a way that won't seem like any sort of badgering.

So what is my next step? Try to contact A by a different method, like text or PM? Try to schedule it through B? Or give up after a fairly minimal effort so far?

END OF MESSAGE

Since A is your current favorite, book another one on one session with her and at THE END of the session (if she hasn't already), bring up the threesome possibility again. If she really wants to accommodate your request, she'll pick up her phone and text B on the spot.  If you don't get a straight answer and/or adequate follow-up, move on. There may be something she's not willing to tell you.

I also don't get the concept that someone could have a favorite hooker that gets really irritated with him without giving any kind of explanation, doesn't answer his PM's, yet is still considered a "favorite".  

 
I agree with Provider A, I think the OP is a little dense too. Why he would still want to do a threesome where at least one of the parties is dead set against it is beyond me.

Maybe I am dense. Here's a brief recap of the recent timeline:

 
May: I see A and I ask A about the duo. She says yes but wants to handle the booking. She recommends that  I see B first.

 
June: I see B and I ask about the duo. She says yes.

 
July: I email A to schedule the duo. No response so far.

 
Now maybe A or B doesn't want to do the duo. But that isn't what they said, or even how they said it. As far as I can tell, the problem last year was that B doesn't work weekends in the summer, and A didn't bother telling me that was the issue. A got irritated when I asked follow-up questions back then, because her brief text wasn't very informative. I just wanted to know if it was a scheduling problem or if they didn't work together anymore, and seemed like a perfectly reasonable question. Texting sucks, because there is no tone of voice or body language to read.

I'm tempted to try a brief text message, just to mention that I sent her an appointment request last week and was following up. But I think that your advice sounds just right. I will think it over today and probably do exactly what you suggest. And I will wait a few weeks before trying to book a normal appointment with A.

I sent a brief, friendly text and got a quick response. A was out of town on vacation. A and B don't work together anymore. A and I will get together soon and figure out a new combination.

are open to interpretation without voice or body. Add in ESL and some messages become awfully cryptic. Happens to me all the time especially with Asian, Spanish and Russian women.

it's been over a year since he tried to book a double with these two, so my advice us to either:

Contact provider A and ask her who she would like to have as a doubles partner and if she responds, book it with her choice of lady. Of course take a look at the 2nd lady to make sure you like what you see.

Start over and forget about doubles with provider A, and search for someone new to arrange a doubles for you. I knows it's his money, however right now it's not getting anywhere. So I'm really thinking he should let whoever he contacts be the one to arrange this for him.

since "they don't work together anymore" it was a problem (other than scheduling) between the girls that your primary girl did not want to disclose.  The few times something like this has happened to me when I was a Newbie, I would later learn that the girls were at two different rates, and they couldn't come to an agreement on what to charge me for the session.  This mostly happened when the girl setting it up had the lower posted rate and the other girl still wanted her higher rate.  If they had just included me in the discussion, I would have told them I would pay both of them the higher rate for this one gig, but my main girl was afraid to tell me what the problem was.  Not saying this is what happened to you, but its one of the possibilities.

Time to move on they have.......You should too. Others out there to choose from.

A will probably dish some details when I see her soon. I have been reflecting on the situation, and it seems that duos can be unstable working relationships. Outside of porn, I can't think of any other industry where business rivals might be asked to have sex with each other. I have seen other duo combos come and go locally, and it seems like client stealing is a common accusation. Another recurring complaint is that one provider is late and the other provider feels that means a lack of respect for her time.

My first attempt to book these two was last year, but my recent attempt was this month, after asking each of them face-to-face in recent appointments. Because of the problem last year, I did ask A about other providers she would want for a duo. She mentioned three, who I will call C, D, and E. She knows C well but has only talked to D and E about duos when giving or getting references.

 
C has been doing duos with A for a two years now. C has a charming personality and used to send me marketing emails once a month, but she is over-priced. Pretty face and average body. Based on the the duo reviews they had posted here at TER, A is bi but C is not really into women. Their duos tend to be tag-team instead of fully interactive with each other.

 
D is an experienced provider who had many positive reviews, including a few duo reviews, and seems like she is really bi. She has a great body and an average face. Her current regular duo partner is locally notorious for her blog, her anti-client attitude on Twitter, and a rip-off review.

 
E has been in the business for about a year. Her early reviews were generally good, but her last ten reviews from 2018 included two rip-off reports. E is about the same height and build as A, and E advertises that she is also interested in female clients, so this could be a hot duo. Or I could get ripped off. She has no duo reviews.

 
A+E would be a roll of the dice, so my best bet is probably A+D.

B—A—bay
B—E—be
B—I—bicky-bi—B—O—bow
Bicky—bi—bow—B—U—boo
Bicky—bi—DUO.
.
It's sounding kind of complicated, but I hope things work out and the threesome results in an A+ engagement!  
.
Maybe like this fun threesome?

and then we could dance this little tune:

In the last two months, I've had a couple of posts deleted from my local board, apparently just for using names. In one case, I started thread where I just asked if anybody had seen a specific provider. I soon got one response asking for the website or P411 of the provider. Before I could reply, the thread got deleted. So this thread was about A, B, C, etc, in order to avoid deletion.

You "named" a provider whose info has been made inaccessible here because of TER's attempts to comply with FOSTA/SESTA.  That's been the case now for several months.  Have you been napping?

I already get it. Tell it to Mr. Fisher, who wanted me to name names in this thread.

Btw, what is with all the hostility in this thread? Are you guys not getting laid anymore? Contrary to what some have suggested here, I'm not a moron, I'm just somebody who was looking for advice. I'm also not a newbie, as I started in this hobby back in 1996.
