hey baby, what's up.

Yes I do the same when a girl answers my email with Babe .  So Phoney !!!!

YMMV!

Your mileage may vary.

It is a fair question and equally fair if you are not comfortable with it!

It is interesting the different attitudes and cultures on the different sites.  There's another place where I spend a significant amount of time where "The Menu" and asking your question is an integral part of the discussion with most of the girls.  Here, as Jenny Bright notes, the more common (and arguably safer option) is to refer the individual to your reviews.  Which, by the way. PGE, you should be doing as often as you can, since they are stellar.  

That said, you may want to keep in mind that your rates are not on the low end of the scale and may very well be a guy's entire entertainment budget for the month.  This could cause one to want to have as good an idea as possible as to what they can expect, which is a perfectly fair expectation.  

Accordingly, providers are constantly balancing out customer service and marketing with their own comfort zone and safety.  Being safe and secure is certainly a very reasonable and understandable approach but recognize that this may also narrow your target audience.  One of the other problems for providers is that it sure seems to me to be a buyer's market.  If someone is unresponsive to such inquiries, clickity, click, tappity tap & voila', there's someone just as cute who is!

Link them to your website/reviews.
If they are being stupid and still asking after all that, they're probably LE or just want a free ride at the computer desk.

How about, "have you read my reviews?"
