Fail rate for me is high on all escort sites I have used: different woman or fake incall location or misleading pics (hiding the fat belly) or maybe teenagers having fun or scammers asking for deposit (I now say I don't do deposits in first text). In PV one option is to go to the white door brothel and to the many massage places and see who is available and go with the closest match. You can't know what the performance will be. Another option is get a room for 8 hrs at Pedregal or Blue (name?), order a chica from an escort site, wait for her by the office and if she is not who you ordered, refuse or negotiate. If you refuse, you have time to order another chica. I have not tried this, but may some time. You can get good info (the white door, massage places) at internationalsexguide.nl for much of the world. They also allow no-show, etc. reports unlike eccie. Best of luck in finding your beauty who does it all.
