It can be associated with new or increased sexual activity or with other changes such as menstruation or sexually transmitted infections.
It can also be associated with the use of soaps, vaginal deodorants, douches, bath oils or bath additives which can alter the normal balance of the vagina. Bacterial vaginosis also appears to be more common in people with a same sex partner.
