• For a change, don't ask "What do you like?" For then you will just get the well-known list. Look at your client from a different angle, as though you must learn to play a new instrument. Where are his sensitive spots? Start exploring and be attentive to his reactions.
  
  
• Don't limit yourself to the genital zone, but try to find other erogenous zones. Has he got sensitive earlobes, or nipples, or an attractive navel?
  
  
• Hint: if someone does something to you in a certain way, the chances are that he is doing that subconsciously because he likes it himself. Use that knowledge.

Many sex workers don't like kissing with their clients. Kissing often has to do with the distinction between private life and working.  Some clients are looking for a woman who does allow kissing. That gives them the feeling that's about paid love and not paid sex.
Decide per client whether or not you want to kiss.

There are many ways of jerking someone off: hard, soft, slow, fast, and so on. How do you find out what your client wants?
You can be attentive to his signs and decide from them whether you're on the right track. You can also take his hand, put it around his penis and ask him to show you. Then you can see at once how he holds it, how firmly and how fast he moves it. 
Jerking off goes better with some lubricant. Sensually rubbing the penis with lubricant is a nice start!

For many men blowjobs are the most favourite sexual activity.
It feels good and subconsciously the 'lower position' of the person who gives the blowjob can be exciting. Make blowjobs more exciting by introducing some variations. First concentrate on the head (and especially the fraenulum, that tiny bit of skin between the foreskin and the head is very sensitive). After that you can move your tongue along his cock before taking it into your mouth.
If you do deep throat (taking the penis deep into your throat) you may feel like retching. When you feel that coming, suppress it by swallowing consciously.
And don't forget the balls. You can lick them or knead them with a hand. The area between the balls and the anus is also sensitive to fondling.

Formerly, licking the vagina was 'not done'. Nowadays, many sex workers offer it and ever more men like it. The tongue is soft and warm. If a client has rough hands, licking the vagina can be a good substitute for fingering.

Fingering happens frequently in sex work. To women, 'fingering' means massaging the clitoris in the first place , whereas men think that they should insert their fingers immediately into your vagina. Some clients need some explanation on how to go about it. So, tell them. It will certainly make a difference for both parties!
You can also finger your client. If you insert one or two fingers into his anus, you can massage his prostate. Meanwhile, you jerk him off or you give him a blowjob. The prostate feels like a kind of swelling, upwards inside the anus. Men often come easier if the prostrate is stimulated.
It's hygienic to use a finger condom. Lubricant makes it easier and smoother.

There are endless positions. Many books have been written about it.
All the same, the basic positions are: man on top, woman on top, doggy-style.

Man on top:
This in itself is an easy position  You don't need to do much. Do follow the movements and make little sounds. This excites clients and usually makes them come faster.

Woman on top:
If you are sitting on your client, it's harder work. A big advantage is that you have more control. If you have a big client (body or penis), this is the most pleasant position for you. You can control how deep your client enters you.

Doggy-style:
Doggy-style almost always increases your client's excitement. He will come more quickly. The disadvantage is that he can thrust more deeply. Take care to rest on your knees in a way that enables you to move your hips along with his movements, so that you do not get his penis too deep inside you.

Anal sex is increasingly done in sex work. Supply and demand are growing. Internet and porn play a role in this. In adult movies, women often take an enema beforehand, thus flushing part of their bowels clean.
In sex work, an enema is not very common. You do not always know beforehand if a client wants anal sex. If you have regular clients with whom you have anal sex, or if clients express this wish beforehand by telephone, an enema is advisable.
When you are going to have anal sex for the first time, the sphincter is not yet accustomed to it. And maybe you are tense. By sitting on top of your client, you can control how far you go.
A useful tip for when the penis is entering: Exhale strongly. Let your mouth fall open. This makes other muscles in your body also relax. Use extra lubricant, both in the anus and on the condom. This makes penetration easier. 
Generally speaking, you can charge more money for anal sex. 

Clients sometimes want you to give a show with a vibrator. This has the advantage that you can decide what to do with it yourself. If you have a rough client, you can evade him, using the vibrator show as an alternative.

Massaging is not a matter of just rubbing and stroking somebody. In an erotic massage, it's important to build up tension.  Take as your point of departure that ‘less is more’.
The more massage techniques you know, the more variation you can bring in your work. Exotic forms of massage, such as Reiki and Tantra are growing ever more popular. An advantage of massaging is that's a way of having safe sex.

Threesomes can be formed in different ways. Is it a couple, you being the third party? Are you fulfilling your client's wishes together with a colleague? Have you got two male clients? Adapt yourself to the situation at that moment.
Generally, you can charge more money for threesomes. After all, you have to satisfy two (or more) people.

The bathroom, or a tiled section in your room, is the most convenient spot for having golden showers.
Golden showers, without knowing beforehand, are difficult. After all, you need to drink a lot of water first, and then it can take some time before you can pee.
Your client lies below you. Ask him where he wants you to pee. That may be in his mouth, over his body or his penis. If the pee won't come out, open a tap so that it drips or let your client tickle you in the low back, just above the groove between your buttocks.  Pee in short squirts; this is generally found to be more exciting.
