Bacterial Vaginosis

Looks like I've I got BV and it really sucks. I feel dirty and I know BV isn't caused by bad hygiene, but when I smell gross I feel gross. I first noticed it when my boyfriend and I were having sex. All I could think about was that he could smell it and that he's going to think I'm gross. I've been on antibiotics but it won't go away and if it does it comes back again. Does anyone know what to do? Has anyone tried boric acid suppositories to help treat it?
