Things that increase your
risk of getting
bacterial vaginosis include:
more than one sex partner or having a new sex partner.
Not using condoms.
Although bacterial vaginosis can be triggered by or get
worse from sexual activity, it does not appear to be an infection that is
passed from man to woman. So experts do not consider bacterial
vaginosis to be a male-female sexually transmitted infection. Bacterial vaginosis may be passed from woman to woman during sexual contact.
