Dealing with this seems as if there will never be a solution. I have been using dove unscented soaps to wash with, following up with apple cider vinegar diluted in water (in a squirt water bottle) to rinse with...always rinse clean with water. This is an ongoing process, I have a daily routine and it comes back when I stop or have my period/sex. I have been working with my doctor to find a routine and solution. Cotton underwear; take daily: Rephresh pro-biotics, AZO homeopathic yeast tablets, and triple strength cranberry--natures bounty. I also drink cranberry juice, lemon water, and plain water throughout the day. Eat spinach, kale and blueberries (I make a smoothie)...its about balancing your diet. What you use internally and externally can throw your PH level off and ruin your fresh feeling.
I also think that high Sugar diets and stress aggravate the issue. Definitely do not believe that this is one issue. I believe that it is also contained in my throat area as well and my doctor refuses to follow up or investigate. I am thinking of visiting a specialist and/or NHS genitourinary medicine (GUM) clinic to get help. I am resistant completely to any of the medication and Antibiotics and have been dealing with this for years.
