My new boyfriend suffers from cornice bad breath. Some days it is unnoticeable but others it is very bad, sometimes it last for days sometimes it just comes and goes.. It is an awkward thing to address, its never been spoken about. I have noticed over the months an unusual foul odor randomly after we have sex. The strength has ranged fair to low and went away after a day or 2 or before i had the chance to take action. With no itch, discharge or other symptoms its gone unmentioned. The smell returned 2days ago directly after sex in the a.m. and I clearly recall he had very bad morning breath, i distinctly know the smell. I recognized that exact smell while trying to douche the foul odor out of me. He preformed oral sex on me that morning, explaining the reason i don t have this problem each time we have sex immediately symptoms after oral sex. How do I treat it now? Is this common? is there a name for this? is it considered bacterial vaginosis? Is this caused by a certain type of mouth bacteria? He will be seeing a dentist/doctor right away. What should i do?

Thanks for your query, I have gone through your query. Usually the halitosis or bad breath will be there in the morning time because of the diminished action or reduced secretion of saliva during sleep. The other possible causes for the bad breath could be the gum infection or deposits, pus discharge. Consult an oral physician and take an opinion to rule out these causes. These causes can be treated by getting your teeth cleaned and maintaining oral hygiene. If it does not subside after getting the teeth cleaned then, it can be secondary to respiratory disorders like sinusitis or gastrointestinal disorders. Consult a ENT and Gastroenterologist to rule out these causes. I hope my answer will help you, take care.
