I have a new sex partner and have been suffering with repeated bouts of bacterial vaganosis. After having sex without a condom, I notice he has an odor, what could be the culprit?

If you are having repeated bouts of BV, I would think that he may be infected and has not been treated. It will be necessary for both of you to be treated and use a condom until this is cleared up.

Talk to a physician about this matter.

Not sure if yeast problems could be involved as a cause... but totally agree with other posters... Sorry I know little... maybe yeast and bacterial issues are same or closely related?
