Limit the number of sex partners you have.
Multiple sex partners increase your risk of getting bacterial vaginosis by
changing the normal environment of the vagina.
Bacterial vaginosis may be passed between women during
sexual contact. If you have a female sexual partner, you may benefit from using
condoms with or careful washing of shared sex toys.4
Bacterial vaginosis is not passed between men
and women and is not considered a
sexually transmitted infection (STI). But if you are
exposed to an STI while you have bacterial vaginosis, you are more likely to be
infected by that infection.
