I have a good friend that's girl friend was recently diagnosed with vaginosis bacteria and is worried that he may have it but is embarrassed to go see his doctor so he asked me and I said I would check into it so what he asked is what are the symptoms in a male and how bad is it if untreated. I am trying to get him to go see his doctor but I can at least give him some temporary relief and good ideas until he gets the courage to see him thanks

It is not clear whether bacterial vaginosis is sexually transmitted, but it can be associated with other sexually transmitted diseases. It is more common in women with multiple sexual partners and it often develops soon after intercourse with a new partner. Bacterial vaginosis is relatively common among women with female partners, where the condition may be triggered by the insertion of fingers or shared sex toys.

There is no condition equivalent to bacterial vaginosis in men. Bacterial vaginosis can occur in monogamous relationships, and it can occur even when the woman's partners always use condoms.

So, it seems that a sexual partner doesn't "give" a woman bacterial vaginosis, but it occurs as a result of sexual contact.
