Newbie 101 Tips - Not meant in any condescending way and not directed at any specific person. Simply general tips for less experienced hobbyists with trans providers:  

1) Never pay a deposit! The only exception I've ever made was for someone I'd seen 4-5 times already and had great sessions with. It was mainly to book a room at a nicer hotel, than a deposit for her services. The only other exception I might consider is if I read 5-6 reviews, by reviewers with 15-20 reviews that were rated an 8 or more where they each said they gave her a deposit and it was all good. Never pay a deposit!  

2) Don't book a late evening or night session with a trans provider expecting her to be fully loaded and spring to attention to top you. Mornings (not too early), afternoons and early evening may work best if you're looking for a top girl. Especially if they're younger and or newer to the business and working in more client's per day. How many shots are in the average gun? There are no guarantees, no refunds, don't be unrealistic in your expectations. This is a business transaction so use your big head setting up the session so you can enjoy using your little head later.  

3) Learn to research the basics for providers with not many or zero reviews. Google their number, email, google their pictures, yes screen shot their pictures and google search them. Look for their social media, look for an only fans type page, maybe even join, $10-$20 can help confirm how they look, they're figure maybe more. Think with the big head not the little, if it looks to good to be true, it probably is. Having a back up in case one seems to go south or you get a bad vibe is often a preventative measure.  

4) Learn the language, lingo, acronyms, top, bottom, versatile, trans, transgendered, transsexual, shemale and or ladyboy, which are derogatory, which aren't. What language do they speak, do you need a translator, do they accept text, calls or email? Learn how many text exchanges or questions and answers back and fourth work with different providers. Learn to be easy going with them, don't freak out or get impatient. At the same time don't compromise the list of rules you need to hold yourself to when setting up sessions, again, big head not little.  

5) YMMV - your mileage may vary is probably the biggest thing to understand. A younger good looking client who's in great shape will commonly get better service than a middle aged dad bod or someone even older. Its a good thing this hobby is offset by money. A middle aged dad body with a calm easy going attitude and the right amount of cash who's not trying to negotiate can also get better service than a younger cocky guy who's in great shape. Let's be honest, she's not all hot and bothered for you personally even if you're a model, she's there for cash, this is business.  

6) Reviews are always from the perspective of that person, that's all. Don't read too much into the embellishments we're all guilty of, stick to the facts and the action that they shared in the review. Someone never to the hobby might think a girl is more hung, while someone more seasoned might say she's average size. Again, YMMV, every interaction between two people will be different, don't expect the exact same thing. Learn to read between the lines in reviews, what they are saying and what they aren't saying about hat provider.    

7) While this is a hobby of fulfilling sexual fantasies, don't expect it to go down like your favorite porno movie, this is NOT porn. Even if you get to make recordings in the session, it's still not the same as porn. If they have an OnlyFans or similar site, those clips are more often with someone they chose to be with. It's more and more common for content creators to work with other content creators. Less and less content is providers with clients.  

There's a lot of other good tips, but I've mainly read about these the last few months. Be careful out there and have fun!
