Is bacterial vaginosis sexually transmitted?

No. Bacterial vaginosis or BV is not a sexually transmitted disease. It is simply a shift or alteration in the normal vaginal flora causing irritation, vaginal discharge, or foul odor. Antibiotics are given to treat bv.
No. It is normal to have bacteria living in your vagina that do not cause any symptoms or problems. Bacterial vaginosis develops when the bacterial composition of the vagina changes, causing a foul smelling discharge. Though it is not a sexually transmitted disease, risk factors for acquiring bacterial vaginosis include multiple or new sexual partners, douching, and cigarette smoking.
Maybe yes, maybe no. The causes of BV aren't known; sexual transmission probably explains some cases. BV risk rises with all the things we associate with STDs: multiple partners, new partner, presence of other STDs, and so on. In lesbians, if one partner has BV, the other ALWAYS gets it once they share vaginal fluids. OTOH, many with BV have none of these risks, and treating male partners doesn't prevent reinfection.

Usually not. BV is a complex and poorly understood. It's overgrowth of bacteria in the vagina--mostly normal bacteria, just increased amounts. Exact causes are uncertain. BV often behaves like an STD, eg more common after new sex partners and in women with other STDs, and can be passed sexually in lesbian women. But heterosexual transmission is uncertain, and treating male partners doesn't prevent recurrence. Read more...

Became sexually active in December. Had Bacterial Vaginosis in February, and now I have it again. Only one sex partner. What am I doing wrong?

Maybe nothing... There is a debate among STD experts whether BV is an STD. It is closely related to sex. Cases like yours support the STD theory, but it's not known if some (most? all?) cases are due to catching a particular germ that causes it. Treating the male partners usually doesn't help. See GUM specialist, check for other STDs, re-treat (metronidazole), and use condoms consistently for the next few weeks. Read more...

Can bacterial vaginosis be caused by a method other than sex? My friend got it at a time when she was not sexually active. She's had 2 partners ever.

Yes it can. Bacterial vaginosis is not really an infection but rather an overgrowth of normal anaerobic vaginal bacteria. The vagina can correct itself but there are medications that can be used to treat it. It is not a sexually transmitted infection. Read more...
Not by sex. Bacterial vaginosis (BV) is not caused by sex, although it is more common in women who are active. BV is not really an infection, but an imbalance in the normal bacteria in the vagina. The healthy bacteria aren't doing well, so bad bacteria overgrows, causing the symptoms. Antibiotics suppress the bad bacteria, but it's important to do probiotics, like acidophilus (in yogurt) to restore the good. Read more...
