Vaginal Odor--I have been treated for bacterial vaginosis for the last 6 years..and it just keeps coming back. No matter what I do, it just comes right back.any suggestions? Im a clean person and I dnt sleep around, I always wear cotton undies and sleep nude so it can breathe down there, I have tried everything...My man has even complained about the odor..I have been tested for std's and all are negative, however my last gyno said that the discharge was "bubbly"....PLEASE HELP
