Here's a fun hypothetical question.  It doesn't work in contemporary English, where there's just one second person pronoun: "you".  But many languages, like Spanish, have a distinction between familiar "you" and formal "you".  Or suppose English had that.  (It actually did a few hundred years ago with familiar "thou" and formal "you", but "thou" was lost to history.)

how I show up for the session.  If I'm wearing a suit and tie, I would use the formal version.  If I arrive in shorts and a polo shirt, I would use the informal pronoun.

I would envision the provider as a "shopkeeper" and the hobbyist as a customer. If I remember correctly from my travels in Europe, shopkeepers feel obliged to address their customers formally. Culturally, customers see shopkeepers as service people and might therefore address them with the familiar pronouns.  

When I lived in Europe (most of the 1960s) I had no money and did no P4P I did one trip with a provider decades ago and we availed ourselves of some local talent mainly in Austria.  I also --again decades ago-- had occasion to hobby a few times in Germany and in Greece. It would have seemed really weird to use the formal form with the local provider just as on first contact with a provider here I can not imagine walking into her hotel room or having her show up in mine and beginning with a formal greeting.  (Rather than a kiss and a hello sweetie: "I am most pleased to meet you madam" say I. Says she: "I too am most pleased to meet you kind sir". though that could be the opening lines in a kinky role play)
But I'm from Brooklyn and may --deep down-- just lack class.

But after any amount of communication it would be rude not to switch to "tu." I don't speak that much Spanish, but I suspect it's only slightly different. Because my Spanish is so poor, I only even try when I'm talking to a Latino who speak no English, which is extremely rare nowadays.

I think I'd do it the same way.  So when speaking Spanish, for instance, I'd use "usted" when scheduling an appointment and at meet and greets, when the communication skews toward professional.  But once the envelope lands on the table and DFK's are exchanged, not switching to "tú" would feel weird indeed.  (Unless, of course, we're doing some sort of a BDSM scene, and I'm the sub.)

I lived in Mexico for several years, and what you suggest seems perfectly logical. While I was not in this line of work there, it was not uncommon that even in professional relationships things went from the formal to the informal rather rapidly.  

Languages are gender normative and patriarchal.  Now I will go cry myself to sleep in my safe space.

might that be considered semi-formal

In French, use of the tu-toi form can imply social position, as with an adult addressing a child, but it is alternately used to imply intimacy, as with lovers or even in prayer. Si je te m'adresse avec la forme "toi-toi" et tu ne l'aimes pas, j'espère que tu accepteras mes excuses.

The second person familiar is reserved for the Deity, royalty, small children, dumb animals, spouses and those with whom we have taken the "shortcut."

and the problem my French teacher (A very lovely young lass I had a crush on already.) had in explaining when to use and not use the second person singular pronoun.

I thought about that too when I was preparing for my first mongering trip to Latin America (Costa Rica) and then realized that it was a non-issue once I got there. The chicas who approached me in Spanish always used the familiar/informal "tu" version of "you." Accordingly, I always used the "tu" form with them and never had any problems.

Can you imagine approaching a chica and instead of saying "hola mami" you were instead to say "Beunos Noches Senora, como esta usted?"

When I was a kid, it was not uncommon to here one adult male (as well as females) get another man's attention with a loud, "Hey, mister!" Used to hear it all the time where I grew up. I don't think it was regional. It was just like saying hello. But nowadays nobody addresses anyone like that. Haven't heard the expression for decades, except once or twice I might have used it myself just to see if people would think it was offensive. But, no, it's just old-fashioned.

I remember researching a legal brothel in Mexico, for a trip that didn't materialize.  I was chatting online with the scheduler, in Spanish, because I know it and wanted to practice.  I used the pronoun "ustedes", the plural formal "you", in a sense of "your operation/company".  (Familiar plural "vostoros/as" is used only in Spain.)  Now that you said it, I might have been too formal; but she didn't correct me, so whatever.

Silly you indeed, what that chica was offering you was 100% legal.

I just got back from a phenomenal mongering trip to Sosua, a significant hobby hub on the north coast of the Dominican Republic. (See the link to my recent post below). I plan to return to the Dominican Republic at some point and would like to explore mongering venues beyond Sosua at some point.

It happened at a run-of-the-mill 3-star resort, around 2003.  The hotel was private, but its nightclub (referred to as discoteca in Spanish) was open to the public; no bueno, in my opinion.  As a result, local providers got in.  I should have known something was sketchy when I saw one of them LFK the bouncer.  As for why she hit on me first instead of waiting for me to do that, I was really shy back then, and she probably picked up on that.

You should use the formal "You" upon introduction but the informal "you" after cumming her in mouth... because by then you know her pretty well.  

You can't go wrong with vous (formal) as in "Voulez-vous coucher avec moi ce soir?".
