I have vaginal odor for a few months now and i want to know whats going on and how to fix it?

Vaginal odor is caused when germs ae living in vaginal mucus and produce gas as they feed on that mucus. These can be germs that traveled there from your rectum, from the nearby skin, or from sexual activity. There are some OTC products in the feminine hygiene section of stores. Failure of these measures would mean you need an exam & tests to sort it out.
