With a trans provider, she will become one of my "pussy girls. "  I will find another lady who still has a cock to fill the void.

Expect almost all of your actual and potential customers who desired you with a dick to drop off by the wayside, eventually, though a scant few may remain as friends perhaps if they are nearby and there is some basis for friendship outside the sexual realm.
...
But that's only my opinion; ask former TS providers who have gone through SRS over a year ago for a better read --- obvously (such as Mia Fever, see link).  And maybe you can fill me in as to why some TSs who have completed full reassignment WANT to categorize themselves as 'post operative' transexuals, instead of their new exterior sexual identity- woman.  Could it be that even post-SRS TSs have remaining sexual attributes (besides the absence of internal reproductive organs) that are noticeably different the GGs?

...and the first one would be are you willing to sacrifice your short and long term mental health to remain doing what you're doing. You need to consider how not doing so is going to effect you. I don't know your personal situation with dysphoria, but in my case, I'm just not willing to sacrifice a necessity for short term economic gain.  

However my own personal situation is somewhat unique, as I don't really need to worry about what happens  after the fact because I've got alternatives for employment. I know thats not a situation everyone else has, so thats another thing to consider.

As far as what happens after, from what I've discussed with other girls that have traveled this path, its not good in terms of business. Though I have noticed that ladies with a good reputation and good relationships with their Clientele seem to fair significantly better. On the other side of the coin there are the comments of the guys themselves. I've asked this very question here previously with a range of responses from not a chance, to doesn't matter. In personal interactions, its also been mixed. About half the guys I've talk to about it don't seems to care either way, but the other half are firm no's. So that seems to reflect whats been said here.

In any case the decision is your and yours alone. So if your dependent on what you do for an income and you don't have alternatives you can transition into, you may want to reconsider.

Personally I'm going to roll the dice and find out. Ive already got surgery scheduled and paid for the middle of next year.

i’ve been with two amazing and well know t girl providers only after they had srs.  

I had wanted to see them before there srs, but when i visited their cities their ads said post-op. i saw each of them (two different cities) and i had amazing times with really cool women who were amazing lovers. i’m still in touch with both of them and hope see one of these ladies next week before she takes some time off

You need to see TS Angelika/Angelica the hot red head.......I have not seen her a a post op but my buddy did and her coolness still exists....she is a smoking hot girl from Louisiana which means she is a genuine person and never would be a rob or scam.  

For a provider who is known to be verse or top, I think the answer is - the drop in clients will be large because of clients who are only interested in getting penetrated. that customer base is gone after SRS.  For a provider who is strictly a bottom, perhaps a small to medium drop in clients. Im crazy about girls who love anal. If I had great chemistry with a bottom provider and the only thing that changes after the SRS is there is one less penis, I think I would continue seeing the provider. I think the problem for post-ops is that if they can’t or wont do anal, the client is wondering why choose a trans woman over cis woman?  if transwomen could feel more safe and accepted in society as pre-ops, I wonder whether there would there be less  desire to have SRS?

Shifts in clients and advertising Post-SRS/GRS

First, due to dysphoria, I could have never done sex work before SRS.  Sure, I had many partners in the sex positive and Kink communities but those lovers were carefully vetted and inherently more open to diversity and the continuum of gender identity as well as bits.

I still advertise as TG /TS.  My reason is honesty in a.dvertising.  I have no desire to provoke anger or resentment for clients who do not wish to see a TS woman regardless of her operative state.  I also feel like it makes advertising tricky for all those reasons.  As someone who is entirely passable and has done vocal training to achieve head resonance (normal girl voice), not even my gayest friends know if I do not tell them or often forget if I have.

So, advertising in TS sections seems off since I do not have what most clients seek from TS women - even though I'm a bottom and also a fantastic Straponista.  But, advertising is the cis women categories means I have to constantly check to make sure would-be clients did actually read the Figures and Facts page on my website.

All that said, I am still attracting high quality clients even with the hoop-jumping.  I think ultimately your personality and looks will win the day, just maybe with more new clients.  

As noted in other comments, every situation is unique, but there are some general observations that you could expect to bear out.  First, based on reads of reviews, the existence of the dick on the provider is the most important factor for a majority of hobbyists in this niche. They’ll talk about looks, personality, kisses, breasts, atmosphere, but the most charged and enticing part of the session, for those in the majority, boils down to the eroticism they experience the moment they have a cock in their mouth, ass, or both (in the case of duos).  You should expect few new clients from that subset.

Second, current clients. I’ve seen encouraging comments here from here from guys who have continued to see a provider post transition.  That’s nice to know. But how often? Did a consistent monthly date evolve into a quarterly, biannual or yearly visit?  It might be time for an HONEST conversation with your regular clientele.  Let them know you’re considering surgery and need to know how it will impact your business. They need to know you value an honest answer over compassionate reassurance, and ask them 1. Have they sought out/dates post-ops in the past? 2. Would they likely see you post-op never, one time thing, or continuing thing?  3. If they date CIS clients, what are their preferences for those women? Tall or short? Slim or not? Racial preferences?  That might be a clue to how your appeal to them will be post-op.

Run a test.  Place ads in a couple of similar markets you know you’ll never actually visit.  In one, run a Pre-Op Stephanie ad. In the other, a Post Op Stephanie ad. Gauge the difference in response. That would serve as a good predictor.

Thirdly, take advantage of your newly created virginity.  Maybe run a “Like A Virgin” tour.  I’m sure there are guys who would pay triple or more for first shot at your new pussy. Once you’re cherry’s been popped, you might be able to advertise “limited availability to vaginal sex (Upcharge for “breaking it in sessions?) in each city?  Once you’re past that, you likely could upcharge for anal/PSE like CIS providers do.  

Lots of possibilities, lots of trade offs, lots of unknowns.  

Finally, have a vision for post-op life.  You’ll be marketing to CIS preferring men who have some level of curiosity. As a tall women, does your weight and body shape need to change?  Looks carry a lot more weight for CIS hobbyists than they do for the guys seeking out TS dates.  Or consider bulking up and consider marketing towards the guys who want to be pinned down, face sat and scissor squeezed by an Amazon lady wrestler? Dominatrix?  Lots of options, depending how flexible you are.

And have another plan.  Get a certificate in cyber security, data analytics, coding. Pick up enhance another marketable skill.  

Big decisions!  Best of luck to you.

I am always searching for post-op ladies.  I quite enjoy them.  I wold hope you continue to provide Greek, as some post-op women don’t seem to want to provide this service.

A few years ago, a good Ts lady that was well known for being a movie star, dropped off and basically went out of business, or at least stopped hearing about her and she stopped making movies.  She was a top notch beauty queen!  Finally found out why she went from being highest rated to being gone from the movie business.  I heard she decided to have the final surgery.  Her name was Leah Chase, AKA Honey Love!

I figure if a Ts has the surgery, then I'll just go find another one in what ever country I'm in, or go with the regular girls or GG's.  However, I do believe that the ladies were right about being listed as "Post-op" in the Ts listings.  I think I speak for most of us hear, when I say we look for the most beautiful ladies, with a nice right size pussy pole.  For those ladies thinking about the surgery, think about what we like about your special attribute, long and hard!  

I know my experience is extremely extremely different, because I’m coming from the opposite side of the experience, and I also didn’t make any surgical changes to my body.  But I did a heavy re-brand once the effects of testosterone started to show in an obvious manner, when I felt it would no longer be fair to advertise as a cis woman and needed to come out publicly as FTM.

I expected to lose almost all of my clients, but I’ve found that those who I have the strongest connections with have stuck around.  I think we connect on a personal level, and although my transition may have caused some uncertainty even amongst my loyal regulars, ultimately they are attracted to me because of who I am and how I am in bed, not because of one particular physical attribute.

I am sure post-surgery you would lose quite a lot of your clients based on what I’ve heard from other trans/MTF providers.  But I’m also sure that some of your most loyal regulars would stick around.  Perhaps be prepared for a lower-volume business model post surgery.  That’s been my experience anyway.  Lower volume, but longer dates, and even more loyalty from my remaining regular clients.

I’ve been with a handful of post-SRS women (only some of which were providers). I will say that their pussies felt very good, albeit very different than a cisgender woman’s pussy. The biggest thing was that regularly reach bottom in SRS pussies. Not gonna lie, I’m not so large as to make that a common occurrence when I’m with cisgender women and the feeling is fantastic. A couple have been dramatically tighter than most cisgender women too. One I was with was actually too tight and I needed to switch to her comedically looser asshole. 😆
