Much of what I am saying below is pretty obvious, but too many providers keep making the same mistakes again and again, that I thought this may be worth repeating. As a hobbyist, here is my advice to providers.

7 Don'ts:

1. Assuming that verifications and reference checks have been done, do not ask for - and definitely do not count - the donation in front of the customer. If you need to, subtly suggest with a smile or a kiss that you'd like to get into the act and like to get the business out of the way. If you need to count, do it as discreetly as possible when he is in the bathroom or go to the bathroom yourself.

2. Never ever ask your customer about the wife or kids - even if you see a ring on him. If he volunteers, keep this conversation short. You are the object of fantasy, not his wife, and dwelling on his marriage is very unlikely to make you a turn on for him (though this could change if you get to know a customer over several sessions).

3. Under no circumstances should you leave the TV on, unless you both want to watch something as part of afterglow during a longer encounter. Contrary to what you may think, the customer is visiting you to be turned on by you, not by porn, so you would not be doing him or yourself a favor if you put porn on TV. If you like to have music, have two or three different kinds and ask your customer if he has a preference. I personally find radio and particularly talk radio very distracting.

4. Do not talk to one customer about other customers - even if he probes. Do not tell your customer that he is the first, last or even only customer of the day. Related to this: do not have old condoms and condom wrappers or used towels lying around. This is something you owe not only to your current customer but also to your previous one (if you take a business card from a customer, put it away immediately).  

5. Talking & Texting on the phone when you have the customer with you: JUST DON'T. This is the single biggest turnoff and the single most commonly repeated mistake. After you check in with your agent, your phone should be put away and remain on mute until you checkout with your agent or he is gone.  

6. Don't run to the bathroom and walk away as soon as he has cum. What you do in the next few minutes are important (see below for some ideas) for how he feels, whether he returns, or how he reviews you.  

7. Don't make a private arrangement with a customer if you work for an agency. When you have a customer who wants to see you again, if you make a private arrangement, you’ll be sneaking and squeezing him in between other appointments made by your agency (which may mean rushed) or have to cancel out on him if your agency schedules something at the last minute. You may well lose a returning customer.  

7 Do's:

1. Make the first few minutes comfortable and exciting for both of you. If you have concerns about his age, ethnicity, weight or whatever, try to get this info in a subtle way before your meeting (or let your agent know that you'd like to know this info before you meet someone), so that you are not taken by surprise when you see him.  Keep this in mind: he probably has some sense of what you look like but has a lot less experience than you; you have more experience, but have no sense of who will walk through that door. He cannot gain experience overnight, whereas you can gain a sense of who the customer is with just a few questions. The more prepared you are, the better the experience you can provide.  

2. Join him in the shower if you can. Almost all men love this and you can use this as some foreplay and get to know time.

3. Think of a tryst as an experience for him – and for you too. The experience does not end as soon as he has had an orgasm. How it’s rounded off counts a great deal as well. Here are some ideas.  
• Do not disengage immediately after he’s cum. Hold him, kiss him or however you show affection and stay in that pose for a minute or so.  
• Use a warm hand towel if you can; if not, at least tissues. TP is crass. Real geishas have a warm towel ready before they remove his condom, wipe him off and also have a little paper fan to dry him off!  
•If you need to remind him that time is up, do so in a subtle way – “would you like to rinse off” or “do you need help with a taxi” – something suggesting the next step rather than “your time is up” or “I don’t want you to run into my  next customer”.  The best line I have heard is “do you like it if a woman puts on your socks? “

4. If you have certain no’s (no DFK or CIM, for example), subtly suggest to a customer you know to mention this in their review. If some review misrepresents or overstates any of your services – and sometimes guys do – the best way for you to correct that impression is to ask a friendly customer to clarify in his review. Alternatively, say CIM is off your usual menu but you provide it for a customer you like, tell him not to mention it in a review. A lot of unpleasantness and disappointment (and bad reviews) can be avoided if you know how to manage your customer's expectations.

5. A nice way to cap off a date is to text the customer after he has left that you enjoyed meeting him.  

6. If you call a customer and someone else picks up – particularly if it’s a woman – don’t just hang up. Say that you are trying to reach Jessica (or some name). The reason is simple. If your caller-ID shows up – or if the customer’s SO is suspicious – someone calling and hanging up increases the suspicion. But if you clearly establish that you are looking for someone else, that gives your customer plausible deniability (that it was a misdialed number). God help the customer who has to explain who Jessica is!

7. Prepare yourself mentally to think of every meeting as a date. If you truly want to provide a GFE, then if you put yourself in the mindset of a gf waiting for her bf, you would become a true courtesan. However attractive or skillful you may be, if you are just going through the motions, it begins to show. But if you really focus on seducing and being seduced, I am sure you’ll quickly rise to the top and build a doting clientele.

My 2 cents.
