I too have been stuggling with this issue for a long time. I am on birth control as well. Ive tried all the homeopathic tricks for yeast infections and BV as well as antibiotics. I just tried rinising with baking soda and water in the shower and immediately that night the taste was no longer sour. It was just a little salty which was not as gross. Waking up the next day - I am the freshest I have been in months! Very little discharge and barely any residual sour taste. Finally relief. Cytolytic vaginosis seems to be the issue here. Everyone should look into it. I think that doctors are ill informed about this condition because they're isnt some medicine that they can sell you for it! I wish i had known sooner.
I'm 24 and I've had this problem on and off over the years. Here's what helps:I typically drink just water and milk. Only cokes and stuff when I'm mixing my alcohol. I don't remember who told me, but it was said that pineapple juice is a really good fixer of these kinds of problems.
Since then, I've kept some sort of juice that has real pineapple in it. (Dole makes a really good orange and pineapple juice.) After 2-5 days, I will notice a difference. I don't drink it often because it's too sweet for me, but it certainly does the trick. I taste sweeter, cleaner, and my girlfriend doesn't mind going down on me without the flavored lube. ;)
As far as the white clumping discharge, it tends to go away with it. Though I know if you're taking any antibiotics, medication, or vitimans, it can change your taste to something pretty bitter. I do take low estrogen birth control to help regulate my periods, but I really don't see that as the cause.
Tangy. The taste is tangy and it's normal. It may be more or less tangy at various times but tangy it is.
What do you expect it to taste like?
aldo, stop with the douching and crazy stuff like that. If your doctor has given you the all-clear, you're fine. Women have to quit with the genital self-loathing. Genitals have odours and flavours and neither of them is mint.
