Re:What makes for an unforgettable experiance?

Make him feel like a king, without being phony about it.  Difficult?  Yes.  You have to use all your senses to detect what will put him in his comfort zone, then rock his world with your talents and your "genuine horniness".  I put these last two words in quotes, b/c that is the real trick isn't it?  A LOT of the times you're not going to be genuinely horny.  And if you try to hard to fake it, your transparency will show through.  I forget whose great line it was, but it went something like, "The key to success is sincerity.  Once you learn how to fake that, you've got it made."  While this was a wisecrack, it is true in many situations.  Keep this in mind, know your talents, sharpen your skills, and then rock his world.

You will find those who are happy to have regular ladies to visit and you will find those who want to pioneer new frontier.
If it is your first experience and the lady does things you've never had done before that that may be enough.  The more experiences you have the harder it is to have that once in a lifetime experience.
At the end of the day when I leave and reflect back on the experience the things that stay with me are:
was there chemistry, did both parties have fun (not a  one sided performance), and did I get my world rocked. I can say I will want to return.

This one still has my head spinning, usually the post session euphoria sort of wears off after a day or so. Not this time, I'm still walking around with a goofy smile on my face.

All of my most memorable experiences started with chatting, kissing, fondling, and stroking like old lovers on the couch (a great reason to book a longer visit), before moving to the bed.  

The single best SP I've ever seen, has the uncanny ability to maintain eye-contact.  In each of my visits with her, every time I look up, or down as the case may be, there were her lovely eyes gazing into mine.

It is easy to fake sexual gratification.  A bit harder to fake sincerity.  But if you can convice the man that you have the same passion for him as he does for you, you will make many a man's day.

Re:What makes for an unforgettable experiance?

It would seem to be an easy answer, but I can only offer my limited insight.  Men seek the comapny for their reasons.  Some men want great sex and nothing more.  I would think they would be the ones that are more easy to figure out which ones they are.  The hard part there would be to continuously challenge the envelope.  Other men fall in the group I am in.  Yes, I wanted sex, but I also wanted a human connection.  An experience rather than an act.  I'm not trying to find someone to run off and start a new life with.  I want someone rediscover life and run with it.  I was fortunate enough to find such a lady.  

I guess my best suggestion would be sincerity.  I know that may not be the easiest thing to do.

Any lady can be sexual, it is the ones that are both sensual and sexual that gets a man to come back.  A sensual lady is the one that can sense a mans wants and needs both mentally and physically.  She tunes into these needs and takes them to another level, where he forgets everything else in the world and tunes into only her.  The next day or the next week, the sex won't be the main thing he remembers, it will be the memory of connecting on another level with that lady!  I know, I've already been there twice.

The ones that stand out for me are those rare occasions when the provider stays for hours beyond what was planned without my asking for it. I know I have no right to expect that, but those are the women I will always repeat with. And no, I don't expect so much generosity from them the next time.

I doubt that's an answer you wanted to hear, but it's honest.

Re:What makes for an unforgettable experiance?

It's all about the chemistry during a GFE experience.  Sometimes the lady says just the right words, sometimes it's her touch.  This all goes with very good (incredible is too hard to come by) passionate sex that makes us feel like we were in our early 20's again.

A few general things encourage me to return - a sense of companionship, foreplay, no rush, a sense of mutual satisfaction.

A few things have happened that have made me a regular while I was in a city - being invited to share dinner with a lovely lady at her home, going out to dinner afterwards off the clock, being invited to meet for drinks at the casino - all things that spoke to a degree of compansionship, perhaps the potential for friendship, and created a tremendous afterglow.

Make him fall in love with you (to an extent anyway).

During the session, if you show him a sense of understanding and make him feel accepted, leaving all worries outside, you will increase the chances of a repeat visit by him.  

For a number of men, there is something lacking in their lives from both a physical and emotional standpoint that they're seeking to get back by visiting an escort.

Give him a great time WITHOUT hitting him up for more cash.  If I have a great time I will always tip more anyway.  Asking for more money is a definite turn-off.
