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?
