The best clients are old ones. You've already gotten used to their personality and are more realxed around them. You've figured out some of the things they like to hear, see and feel. New clients are great because that means more experiences and income but how do you make them all stay?
Study them but don't make it obvious. This is the way to know what approach to use because though people are essentially the same, the differences are where it's at. Listen, most people are in a hurry to talk and it's refreshing to notice another person absorbed in you. To prove you are listening, nod, take the conversation back to something said earlier or even reference something mentioned on a different day.
It's nice to be lavished upon and it is likely your client feels that way too. Give small gifts occasionally. Of course he/she is not going to expect you to carry the financial burden of the relationship because they are aware of the dynamics. Gifts make people feel special and in the long run, more willing to spend. The more thoughtful the object, the more touching. Pick up what they like and surprise them.
Dress to impress that particular person. Note which outfit gets complimented and stick with that style when with the client. Look nice generally. Several trends come and go but a classy lady will turn heads. This will make you look like a trophy and who doesn't look like to show off?
As you study them, pick up their interests amd learn as much as you can about it. People crave the familiar and a hobby is fertile ground for bonding. This also ensures your conversations stay interesting. Of course you have to be versatile with topics so that you won't come across as empty-headed (unless you feel this is the kind of woman/man they want). Mirror them by learning their body language. The subconscious effect this has is crazy. Does he scratch his eyebrows with his index finger? Start doing that. Ensure it's as natural as possible to avoid creepiness.
Be unavailable sometimes but don't over do it. Absence makes the heart grow fonder. Give him space to miss you. This also gives the impression that your time is priceless. Cheap goods come easy. When you are with him dazzle. This can be achieved by doing something out of character every once in a while. This will keep him interested in discovering more to you that may not even exist. Mixed messages are perfect for feeding his mind with thoughts of you. So, don't fail to send them.
Sex is a big part of many escort-client relationships and just like in a romantic one, it can make or break. You just have to be an awesome lay. It is a show, make it worth the tickets. Work for your money. Pick up new skills. Study their idiosyncracies and you are sure to keep them lusting after you. The want something fresh, keep it that way.
Dish out compliments but don't lie. If you notice something you like about them, don't keep it in. Most people are insecure and need the flames of their egos stoked and it's your job to keep your clients happy. A happy client will not just be loyal but more willing to pay well.
It's a travesty to lose clients but when it happens don't beat yourself up. Use it as motivation for self-development. Also, you can't satisfy everyone. Good luck!
