Hello. : Hello. I think it would be helpful if you knew what type of bacterial vaginitis you have. It is important, because if it is a sexually transmitted disease, you would want to make sure that you are not passing it back and forth with your partner. If it is a yeast infection, that can occur often if you are taking antibiotics and some women develop them more easily after sexual intercourse.
