Not much is known about how women get BV. Any woman can get BV. But there are certain things that can upset the normal balance of bacteria in the vagina, raising your risk of BV:

* Having a new sex partner or multiple sex partners
* Douching
* Using an intrauterine device (IUD) for birth control
* Not using a condom

Bacterial vaginosis is more common among women who are sexually active, but it is not clear how sex changes the balance of bacteria. You cannot get BV from:

* toilet seats
* bedding
* swimming pools
* touching objects around you
