I've never been to one of the Asian agencies, but I'm curious since the girls are so hot and several get petty good reviews.  After researching and reading lots of reviews I'm curious about a fews things.  

There seems to be an established "routine" that most of the women follow: Greeting, brief seated bbbj, shower, massage, rimming, more bbbj, CG position (and maybe a few others), then done.

I realize YMMV a bit, but how flexible is this routine?  I'm not into rimming at all and while I might enjoy a massage I'd prefer to make it brief and at the end of the session. I also understand that during the shower or massage most of the women do a privates-to-privates grind and I'm not comfortable with that sort of unprotected contact.  Also, I normally like to call the shots as to which positions we explore, and while I'm sure some of the providers are flexible in this regard I'm not sure how common that is or which providers tend to be less "scripted".

Also, I get the impression that it's fairly common for the pics in the ads to not be of the actual provider, but of a model who looks similar. Maybe I'm wrong, so please enlighten me.

I'll might end up giving it a shot and just communicating my preferences to the provider up front to see how it goes, but just thought I'd see if anyone has any suggestions or further input.  Thanks.

Most of the girls I see don't have a routine. Most of the times, they join me in the shower for some foreplay, then start off with a message. Then the BBBJ, and I can DATY if I wanted to. I don't like girls to rim me, and I tell them not to. Most of the times, I get Mish and K9, and some CG if I wanted. After that, a quick shower and I'm out the door.

These girls seem to take directions well. You gotta lead the session, and tell her what you want after you have established what needs to be established. It's basically like any other women, just tell them what you want and they will accommodate you
