 [ Symptoms ] is it harmful for a man to give oral sex if his partner has bacterial vaginosis [ Disease ] hi it is unclear how women get bv it seems to be associated with sexual activity but women may get it without being sexually active it is most likely an imbalance of the naturally occurring bacteria found in the vagina too much bad not enough good what is known is that there is no infection like bacterial vaginosis bv found in men for all of these reasons it is very unlikely that a man would be harmed by having oral sex with an infected woman however one of the most common symptoms of bv is having a vaginal discharge with a very strong embarrassing odour so it is very unlikely that this has a chance to be tested very often if you know what i mean but sorry i do not think i would like to go there what with all that cottage cheese and the odour i think i would give it a miss till she gets better but if you must go for it good luck
