in reading your reviews and viewing your web site you matched up so completely with his desires that he felt you were just too perfect for him (To good to be true). A good thing I would think.
The other less flattering way is that after reading reviews and such he felt something was fake about what he saw.

I tend to go with the first as if the second where true I doubt you would have seen him.

Just my thoughts (such as they are) and may be completly off base.

Speaking for myself I think your pretty d@#n good!

before he saw you and saw you anyway or did he put you on his TGTBT list after the session?
If he put you on his TGTBT list after the session, I have no clue unless he is complimenting you by saying that the session was and you were so outstanding that it's To Good To Be True. Like saying it was so good he couldn't believe it even after he experienced it.

I hate to say it but he also could have felt that no one could be as good as your reviews etc. say you are and after the session he has confirmed in his mind that he was right. Meaning you didn't live up to your reviews in his eyes and he is disappointed.

Did he give any indication what he meant? Did everything go well? Were there any difficulties during the session?

Speaking from experience we don't always connect with the provider.  I believe it has more to do with our own expectations and sometimes the provider might have an off day.  Speaking for myself and experience with you I believe you are an incredible human being and indeed very Good!!!  Don't worry.  We are all human and can't have a perfect performance all the time.  I guess as I grow older I have become a lot more realist :0)

I agree,  Our performance should always be priority, but off days happen, we are human

As a guy that excels in saying the wrong thing but having the best of intentions when I said it; I think he was giving you a compliment.  

True, there are two ways this could be interpretted.  But given the fact this comment was made 9 hours after the session, I think he was saying a) his experience with you was beyond anything he could have imagined or b) when he relays his experience to others, they are simply not going to believe him on just how good it was.  Not sure about anything else that was communicated 9 hours later, but the basic fact that you had a communication with him suggests he did not mean anything negative.

Many of you ladies are quite gifted in terms of skill sets, including oral abilities.  If we guys were as gifted with our words as we sometimes think we are, well - the hobbying ranks would be proportionately reduced by the increase in guys trying to pick up ladies in public venues. Course, that is just be my opinion - hard to talk when my foot keeps getting in the way.

He thought you couldn't possibly be as good as your reviews etc indicated. (TGTBT) Then he saw you anyway and found that you are indeed that good, even better. I'm guessing then your question is more about how could he have thought you were too good to be true. He would have to think that based on his past experience. He has heard/read of others that were just fantastic and when he saw them they were a disappointment. Not really anything you can do about his past experience and how it effects his decisions. Just understand there is a lot of hype out there about how good something or someone is and many times it/they just don't live up to the hype. AH!! But you did. Kudos to you!

I'm guessing you are also wondering if others that haven't seen you think that. Again you can't do anything about that. All you can do is be as good as your reputation says you are and let guys like him go out and tell others that he thought you just couldn't be that good but once he saw you he found you are.

Your questioning also says a lot about you. You are conscientious and want to do well in your endeavors. You have good reviews and a good reputation so you're wondering how someone could doubt you. Believe me it's all about them and their experience and in no way reflects on anything you have done to make people doubt you. You haven't done anything to make them doubt you. It's all them and how they were disappointed by others.

Well in that case it sounds like a win win. He thought you were to good to be true and you showed him were better then that!

You have exceeded my expectations everytime I see you....
