Bacterial vaginosis

I seem to be more proneto getting bacterial vaginosis than other women as far as I know and I'm wondering is it just me or Are other woman also more prone to getting bacterial vaginosis too? It's not an STD it's an infection occuring when the vaginal flora is disrupted. It's usually asymptomatic but can cause a fishy odor. I usually have it when I have a new sex partner. I think this is the 4th or 5th time I've had bacterial vaginosis in the last 10 years. It requires antibiotics to get rid of it.
