How do I mention to her about rimming in a session and it's preparation since any mention of sex is disallowed before a session?  And if that's not enough, how about if she's with an agency and have to speak with someone else.

Is it ok to ask if she speaks "asian"?    

Thanks in advance!

ahead of a session.  That is a sure way to get a dial tone or be cut off.

Instead, look at a provider's profile and reviews and use them to determine what items you can expect.

It's unfortunate, but that's the way things have to be as long as LE is out there trying to entrap gals by getting them to admit to trading sex for money.

If it's not on her website or in her reviews, it is best to not expect it on the first date. Then when it is no longer an LE issue, you can ask her anything, the worst she can say is "no".
