If there is a provider's ad that you see, particularly on BP, is it "bad form" to ask if she is BBJ?  I know a lot of these chicks specifically put in their ads, "No discussing of sex acts" or some such shit.  But, if I can't ask, and I get there and the chick is CBJ.  I'm out the fucking door.  Shoulda told me in advance.  
 
I know that some of you ladies advertise on BP as well as ECCIE.  So your input would be appreciated.
 
How to handle this one?  I normally get at least SOME intel on a chick before diving in, but I'm horny, tired of waiting, and she's in the budget-range, so I'm really thinking of going in blind.
