My vagina has a very strong odour, even after i take a shower. recently my anus does that as well. i usually have to shower twice. what can it be?

Overgrowth: most likely this is some overgrowth of bacteria in the vagina and possibly in your rectum. If you're not having any pain or discomfort, that is a good sign. Can see your doctor for examination. Treatment might be available to restore normal bacterial growth. Tends to occur in couples who practice anal and vaginal intercourse. Hope this helps. Best of luck.
