When I read a review and the provider is described as sub, what exactly are we talkinga bout?  I understand in a DOM sort of way, but what does this mean w a full service provider?  Does she want you to take the lead?  Maybe she wants you to order her around a bit, be a little mean to her?

gals who liked there buns paddled until they are raw.

And everything in between.

Look up BD/SM gals and then read their reviews.  If you must, tactfully discuss with them the possibilites.

They are a rare breed.

When a provider says she is a sub she is letting you know that she is into the fetish scene but on the submissive level where you are the one to take the reigns.

I have been doing Pro Domme in NYC for some time now and when a client says he is a sub it is the same thing. That I (or in in your case you) are in complete control of the situation.

Her level of submissiveness may have to be explored to see where she stands on that and what her limits are. You can test the waters with the spankings, bondage etc. Depends what you are into to see how far you want to explore.
