Don't put yogurt in your vagina. For that matter don't put yogurt in your butt either.
Not all itching and burning sensations down there are yeast infections, sometimes it's just an allergic reaction or some kind of skin issue.
I think it's wonderful that we have over the counter monistat yeast treatments, but the idea that people abuse them not realizing it's something else is very troubling.
Take care of your stuff down there.
