I am 20 years old and for the past 2 or so years have experienced bad vaginal odour on and off with no real pattern except that I think it is definitely worsened after sex. I have had the same sexual partner and have had tests for STD's on more than one occasion which have been clear. I went to a doctor and was told it may be BV which I was tested for amongst other things and the results came back clear again. I now have no answers and have tried lots of different things as well as maintaining very good personal hygiene. Any suggestions would be greatly appreciated.
