Hello fellow hobbyists,
I'm new to the hobby and looking for suggestions.  I'm 51 looking for 18–30-year-old top, DFK and 5-6".  I've read a lot of different experiences with girls claiming to be GFE or DFK.  Some say it in their ad and then the reviews tell a different story.  Is this just due to the lack of chemistry/attraction?  I'd hate to pay for VIP GFE and then not receive DFK.  But totally understand if the provider isn't into it.  I just don't want them to take my money and then be expecting it only to hear, I don't do that.

Any advice is much appreciated.  

One last thing, how come some providers are not on here?  There's one in my area that I've been itching to get some of, but I can't find any reviews on here.  Is anyone familiar with Roxy (I know she says she is 8-9", but I'm thinking I might want to try if she is gentle)?

I will suggest you do lots of research and learn from the reviews or contact gentleman who have seen them.  
You only get one chance at a first experience. I’m sure you will find yourself nervous and even a bit scared.  
Contact your provider to explain your expectations for DFK and Top. Most likely they have their own idea for the term GFE.  
I’ll give you a bit more advice to be sure to practice and practice. No matter how much you use a toy nothing will compare to the real thing.  
Good luck!

Thank you for the suggestions.  I joined this community so I could read the reviews and do as much research as possible.  I've read so many reviews.  I've learned so much already, but like you say nothing will compare to the real thing.  Thank you for reminding me you only get one chance at a first time.  The small head was starting to take over the decision making.  I'm definitely going to be scared but that's what makes it so fun right?  A totally new experience.

I'm apprehensive about asking too many questions of a provider, as I've read reviews that sound like they can get pissed off when you ask too many questions and I definitely don't want to start a relationship that way or be perceived as showing them disrespect.

As to contacting gentleman who have seen them, this seems weird.  Is this something you have done?  What were the responses?  I suppose it could be useful especially if they say do this, she goes wild.  What could I hope to be gaining that is not in the review is what I'm saying?

Anyway, great suggestions!  Many thanks!  Love this community!

Hobbying with Cis girls and hobbying with TS girls is totally different, especially for someone looking to be topped. A Cis girl can literally lay down, spread herself open and let you do all the work, then claim it was good service, and many guys will agree with her. That's not the case with someone looking to be topped. You're asking someone else to do the majority of the work. Plenty of great TS providers out there who can and will. As has been mentioned, research reviews. But, understand that reviews are subjective and what happens with one customer, may not happen with you. My suggestion is to find a girl you like, prepare properly (clean and stretch your asshole and guts, getting fucked is more intense than dildoing yourself and without preparation you can ruin a session) and understand that you may not get exactly what you want. Bottoming means giving up a little control to someone else. Obviously, a good girl will listen and do what you pay her for. A really good girl will push you and do more than you pay her for. A really good girl who you've established a relationship with over time will blow your fucking mind.
Also, as someone who TOFTT quite a bit, I would be very wary of the ad you posted without reviews. Providers who have no reviews mean no one who has seen them has submitted a review. They could be a new provider, maybe they just arrived to the USA or recently decided to try sex work, or they could be a scammer who had shitty reviews and changed their identity to escape them. Who knows? I do know that if you are set on getting something specific like DFK you're best off knowing that girl may do it by seeing that she has with others.

I attached JMaps link to his thread on tips for Newbies. Great tips shared on that thread!  

In my experience GFE or DFK heavily depends on how attracted the provider is to you & the time of day you meet. I've paid for GFE before & still got mediocre service. I've paid the regular hourly rate & got GFE service. The GFE up charge is 80 - 90% BS in my experience. Also depends on the time of day you book, if it's on a high volume day/time like a Friday or Saturday night than it's going to be harder to get that GFE type of service.

Unfortunately, you will have to go through some trial & error. Not every provider you meet is going to be a 10/10 experience. But reviews definitely help weed out the bullshit providers & help find the right ones based on your preferences.  

If you're in ATL area looking for a top definitely see TS Lena (TER ID: 336807). Saw her in 2020, super sweet, hot body & huge dick! She is Vers too if you like to top. I haven't seen her ad's recently but she still post on Twitter. Her Twitter is TSLena2221 if you wanna see her cock.

Those are great suggestions.  I really appreciate your advice.  As a newbie to the escort game and the TS world, this site and advice like yours is invaluable.  I've only been with CIS girls in the past.  Girlfriends.  This is a completely different world.
I bought an anal douche so I've been practicing getting clean.  Usually 3-4 rinses with warm water does it.  I also bought a butt plug.  What do you recommend for stretching my asshole and guts?  Dildo?

Many thanks.  Great advice.  This community is the best.  So supportive, knowledgeable, and essential, really.  I'd be so lost.  That's a great tip regarding day and time.  I didn't really even consider that.  I'm definitely going to check out that link.

TS Lena looks delicious!  I'm not sure I could handle that right out of the gate yet.  I need to put some miles on this booty first.

If you can buy a douche that connects to the shower head that's ideal. It screws on to shower head or the handheld shower head. It saves time & cleans you out really well. Always use warm water. Just type "Shower Enema System" on Amazon & you'll find some good brands. Not expensive either.  

 
For Anal Training start with using butt plugs. Sit with them in for a good period of time. Then gradually increase to larger and larger plugs. After a while your asshole will learn to relax with something being inserted. Then practice with dildos.

Lots of threads about proper preparation for bottoming, I’d just search and read.  
I always go with bigger toys than the dick I’m about to get fucked with. And poppers. Poppers help a lot.

I really, really, really LOVE good DFK.  
But twice in recent years when I've gone there, Covid cropped up a day or few later.
Hooked up with a lady (TER ID: 382496) last August - copious FANTASTIC DFK, but a day or two later my throat's all tight, I'm starting to cough, and 2 lines on the Covid test.  Bleech.
Makes sense: intense DFK with lots of clients is going to bring along lots of exposure.

2020, 2021, and 2022 my dentist had all patients swishing hydrogen peroxide before the hygienist would go in.
Now before and after any date including DFK, I'm swishing peroxide+mouthwash before and after.  Don't know how effective it really might be, but it seems an easy precaution.

If Jasmine/Gia comes back to my town and I have the time and funds, yeah, I still want to do lots of DFK.

I just want to thank everyone in this hobbying community and especially this thread for their wisdom and advice.  I used all the knowledge I found through this community to prepare for, find and have a mind-blowing experience!  I'll be posting a review soon (I have to marinate it in my mind for a couple of days.  This girl was special!).  I'm sure everyone says that about their first experience, but she was just so personable.  She made me feel like the only guy on the planet.

Anyway, many thanks, and gentlemen; HAPPY HOBBYING!

Welcome a board.  
You came to the right place.

Yes definitely buy a shower attachment for your shower if you want to get comfortable. But warm water enemas will do the trick to. I use them whenever I’m traveling.  
Yes definitely practice whenever you’re ready. Butt plugs are good for training but I find that you need a dildo or object to strengthen your ass muscle.

My favorite way to pick a provider is to go to where there is the ladies on the street corners.  Like that one sweet street in Sao Paulo.  It went for a mile or 2 with the T-ladies on every corner!  
Or it can be good to go to the building where there is a lot of them, and they can be paraded past you.  Then you can pick one of the ladies.  They're popular in Spain!  Usually those places have the girls checked, health and legal.   The closest place I know like that, is San Jose, Costa Rica.  And also in Colombia.  A buddy there gave T-lady tours.  

My first time was when I had 4 of the ladies jump in the car.  That was in Panama City and none of them could speak english.  The next time I flew down there, I met the best T-lady and her name was Carla!!!  She was beautiful and very loving, and into any kissing or anything else!!!  I've learned how to get by, when you are in a country where they do not speak english.  Like now holding the phone to a interpreter / translator.  Or you can just have someone at the hotel check-in, talk for you on the phone.  And have them get you a taxi driver that speaks english.    

And one last thing on the ladies, they respond well to gifts and respect!  Taking them out to a nice place!  And a sweet sense of humor!  Getting their smile right side up, can be a big help!  Going outside of the country might sound like a bit much, but after the airplane ticket, it can be ten times cheaper.  Meaning you might see 10 ladies there, for what you see one in America.  I met the Miss Trans of Brazil and Panama, which was great!!!  Use the "Search" to find the info, that me and others have put on here.  Type in the city or other subjects.  I traveled a lot for my work.  And I took full advantage of it!!!  
For travel info, TripAdviser.com is good.
And one last tip, save what you typed in, this does time-out and you can lose everything!
