Every healthy woman has her own noticeable vaginal odor, even if she practices proper hygiene. It is similar to light fermented milk or musk.
However, the odor is not always the same. Its nature and intensity depends on ones age, psychological markers, physical activity, menstrual cycle phase and other factors.
For example, the vaginal odor can become more unpleasant after unprotected heterosexual intercourse.
This is because the pH balance of the vagina is 3.8 to 4.5 and that of the sperm is 7.2 to 8.0. When they come in contact, the vaginal flora is destroyed.
The same happens when menstrual blood (which is slightly alkaline). This explains that metallic smell during menstruation.
You don’t have to get rid of the natural vaginal odor, but if there is increased vaginal discharge and the odor becomes stronger, unpleasant or fishy-smelling, and is accompanied by itching and burning, you should see your doctor to rule out any health problems.
