I had a recent visit with a provider and we did prolonged DATY - probably 20 minutes - and I absolutely loved it!  She told me twice afterward that it is very rare that she allow someone to do DATY, let alone that long.  I wasn't sure how to interpret this.  On one hand, I don't want to accuse her of lying, but on the other hand, don't want to be naive.  I figure it means at least two things:
1.  She feels comfortable with me
2.  She doesn't want me to let others know she allows DATY.

Any insights into this?  Do providers often say things like that just to make us feel better?  Like saying "you were great!".

Like if she claims she does CBJ but for you it's a BBBJ.  Well, maybe it's a CBJ if if they need to wash.
However DATY may be different...  she may in fact avoid it for various reasons.  One Fav sometimes avoids DATY...  because she does in fact cumm so hard she needs a recovery period before she can squeeze.  Depends on her mood.
My ATF, we try to keep some variety and sometimes make it all about me but other times a more shared experience.  She also told me she does not cumm with clients...  of course I'm still leaving a donation on her dresser but she can have long rolling O's.  

So she may in fact like your ministrations...  providers are women too...   Some ladies may have strong preferences & rather not let someone start than try to stop them if she doesn't care like what the client is doing.

I think she probably did feel comfortable with you.  It's also quite possible she doesn't let all her clients stay down there so long, who knows why?  Providers will pretty near always tell you what they think you want to hear, even if they are lying through their teeth.  Why, you say?  Simple, they want you to come back.  It's also common for some providers to not really enjoy receiving oral, just as some will only do a cbj.  It's  YMMV (your mileage may vary) thing.  

Since you love giving oral, you lucked out here, so just enjoy it, and don't worry about the why.  She let you do it, and you did, that's all that really matters.

reviews? Did other guys DATY?

for us. Your post reminds of the old joke, "when do you know a used car salesman is lying to you? when he moves his lips" Now, don't get me wrong, there may be just a glimmer of truth to her statement, but none of use were present when she utter those words to you. So it's impossible to really know if she meant it or not. Take it with a grain of salt and you'll be fine. And please ladies my joke was not meant in a disrespecful manner. Finally, do you plan on writing a review of this experience?

Thanks.  I'm not sure if I am going to write a review.  And if I do, should I discuss what I include in the "juicy details" with her beforehand?  Not talking about my ratings - just how much detail to add.

I read a review of a lady that would tell guys "well I do not do this with everyone" when I eneded up seeing her she gave me the same line.  I guess she did not read her own reviews.

and hopefully been helped with the replies. So now it's time to say thank you to the TER community by writing a review. I never discuss reviews with the provider I've just seen, if ask by a provider after a session, will I write a review, I'll say yes, and that's it, I cut the conversation off.

Some providers don't like you to go into gorey detail, if she has other reviews, read the juicy details, she's probably read them, so I would write a "mild juicy detail" Read reviews of other providers and find a style of review that you like. Do not plagiarize, but use it as a template for your own review. Eventually if you decide to write more reviews you'll develop your own style. In LA there's a hobbyists named pauliewalnuts, he writes great reviews.  

Remember the founder of this site, started it because he was getting ripped off by so many bad providers and he wanted a way to alert other hobbyists to both good and bad providers. There were no review sites at the time and the internet was just starting.

when I hear guys say "I dont know if I will do a review", it kinda is like saying I'll use your info  but why should I give any back.
 Kinda selfish imho and if your gonna use this website...DO THE REVIEW!

If you want to write a review, do it. If not, then don't. If you want to discuss what you write with the lady first, do it. If not, then don't. This isn't a test. There is rarely a right or wrong answer. Ignore the guys that try to tell you what to do, they don't have to live your life.

As for your original question, if I had to bet my life on whether she was feeding you a line, I would bet yes. However, she's the only one who will ever know the truth for sure. I tend to just go along with whatever the ladies tell me. What's it going to hurt?

Who cares?!  You're over analyzing this.  Some people say things with honesty and some don't NOT just within the hobby.  Move on.
