A few years ago there was a provider from SF (Burlingame) called Yumi.  Her husband was literally in the next room, the dude was huge!!.  She had pleanty of reviews so it was totally cool but just a bit unfortable at first.  

As long as they have a good reputation I wouldn't mind going through the bodygaurd.  I think the ladies these days should take every precaution to safegarud themselves.
