I hear ya! If you have ruled out a bacterial infection, or major wack in your vag. flora what works for me is two-fold. Try rephresh (not replense)as directed. THis kinda thins things out and keep stuff moving. A nice side effect is once it starts 'working' you will find yourself more willing physically to have sex. You cannot use it more than the every 3-4 days as instructed.
A MAJOR helper too (even though it sounds funny) is to get yourself some small girlie clippers (for bikini line - they have at walmart)and use those to clip close all OVER down there. You don't have to bald it. Just like when you shave your armpits, and your deordorant works better because of better air-flow.
I honestly still wear a panty liner for like the first half of the day and ditch it in the afternoon and I think it helps alot if you don't even wear unders at night.
Anyway, good luck. This regimine has truly worked majic for me!
