In Bahia there is a professional gay tour guide who could help you. He's taken some of his clients to saunas. He's on TripAdvisor.com, and his name is Fernando. ...can't remember his surname. He use to have his own website, but I do not know if it's still up or not. He could give you some other pertinent tips, too. Have him take you away from Bahia to an island to enjoy from another perspective. WHILE on this tour, you can ask him lots about gay life in Bahia!
