Some say oral sex contributes to infections because of bacteria, but I certainly wouldn't let that keep me from getting it. I'm quite sure oral sex isn't the culprit with BV as much as semen b/c it changes the vaginal pH. Your infection is cleared, so if I were you I'd go ahead and do it. My bf and I do it all the time and I've seen no correlation between that and my BV flare-ups. BV is the biggest nuisance EVER, but I'll be darned if I'm going to let the fear of a flare-up keep me from getting oral!!
