This whole hobby thing is a crap shoot.
How many times have you heard, "I don't do this with everyone"!
Given that statement, would you include that activity (DFK, BBBJ, etc....) in your review? If so, what would the level of expectation be with that provider for other customers who read the review, if she really did mean what she said? And then, how would your credibility and discretion measure up with her on subsequent visits, if she was pissed at you for mentioning that activity, whatever it is.
When I visit a girl, I try not to have any pre-conceived expectations, that way there are fewer disappointments.
I dunno man; everything you read here is subject to scrutiny and should be taken with a grain of salt.
Sad to say, but the most credible reviews are probably the "No" recommendations.
Just my .02 worth.
