I like to do engage in specific acts or act out a vivid role-play or maybe I just want to have a GFE experience.
Question:  What is the best way to effectively communicate what I wish to do with a provider without getting: a) hung up on, or, b) having my email deleted w/o an answer.
The couple of providers I have seen - who both advertised role-play, GFE, etc - wouldn't discuss specifics even face-to-face.  What 's a brother to do?

that you read reviews, do the research and find the provider that is the closest to meeting your needs, book her for an initial session and if all goes well, then talk with her about some of you specific requirements for a future session!

Never never communicate your wishes over the phone or in and E-mail.  Sometimes it takes several visits to allow the lady to become comfortable with you to communicate your wishes face to face.  This is more so, the more unusually your wish.  Good luck

A good way to ask would be something like this: "Are there any rules or restrictions that I need to be aware of?"
