If I have bacterial vaginosis and I have unprotected sex with my bf is he gonna get an infection as well?

Not necessarily. Bacterial vaginosis which is very common in women usually is not spread to the male. However , if you get treated, your symptoms resolve , and then return again after sex with your partner he may be infected in which case you should both be treated at the same time. Before he asks , bacterial vaginosis is not consider a sexually transmitted disease. Virgins get it.
