I use to think that also. If you aren't looking for it, it isn't offered. If you seek it out BBFS is all around you. I'm totally retired out of pooning now but I can assure you that some of the biggest names in Van have given up BBFS.
You should definitely quit pooning today then. Despite the denials in this thread I would say at least 90% of the girls offer BBFS to at least one/some of their clients.
