I have had it at least 6 times this year alone. I keep going and getting treated, but it comes back in a couple of months. Could my bf have it and keeps giving it back to me? He doesn't show any symptoms of having it though.
So is this actually an STD? I have never cheated on him. I have been to the doctor several times since we have been together to get tested. I am clean except for this. Do guys have symptoms at all?
Do you know of any home remedies? Other than the ones suggested.

BV (Bacterial vaginosis) is NOT an STD.

Bacterial vaginosis (BV) results from an overgrowth of organisms that are normally present in the vagina. Usually, "good" bacteria outnumber "bad" bacteria in your vagina. But if bad bacteria become too numerous, they upset the balance and bacterial vaginosis results. This type of vaginitis (bacterial vaginosis) can spread during sexual intercourse, but it also occurs in people who aren't sexually active. Women with new or multiple sex partners, as well as women who douche or use an intrauterine device (IUD) for birth control, have a higher risk of bacterial vaginosis.

If you have been diagnosed with bacterial vaginosis (BV), you can use lactobacillus (as in yogurt) to help restore the balance of vaginal bacteria, either along with or instead of antibiotic treatment. If you are pregnant, remember to avoid vaginal administration of any treatment. Lactobacillus organisms stop the growth of harmful bacteria, boost the immune system, and increase resistance to infection.

Men can NOT get BV so he is not passing it to you. Some women can get BV several times a year. Talk to your doctor about how they keep reoccurring for you and maybe there are some other options you can take.
