Meetings with WGs should be enjoyable, pleasurable but encapsulated experiences. My position is to keep punting and private lives very far apart. The only outcalls I ever do are in hotels if I'm away in another city. Most of the time I expect her (as the service provider) to provide the venue. I suspect that many WGs would come to your home, respect it and your subsequent privacy, but how would you know this in advance? There are enough risks in punting without this one.
