I'm interested in the same thing as well. There are lots of ads on BP, but I see almost no reviews of them here except for those who only provide incall - whereas I am mostly interested in outcall.
I know it it also probably an extremely delicate subject, but it also appears that there are a whole lot of massage providers who seem to think that men only like providers of gargantuan proportions. Whether this actually discourages those who are more on the petite/slender size is hard to say, but I hardly think I'm the only hobbyist that prefers that type.
It is possible to find pleasant endings on Buford Highway, but sometimes it takes quite a few visits to the same place before that becomes a possibility and even then only certain providers do that. Tips seem to help.
