My partner and i had oral sex for the first time. Prior to doing it, I noticed that he had halitosis. Now that its official that he has sinusitis, which caused the halitosis, i'm wondering if its possible that i might have gotten an infection because of him having sinsusitis while doing oral. I have an strange itching sensation in my vagina. its almost like its bruised, while itching. Could it be an infection, and if so, what type?
I don't think he transmitted anything to you. If he had thrush/ candida overgrowth in his mouth, he could give you a yeast infection but I don't see how his sinusitis caused an infection in your vagina.
I don't think he could have transmitted anything to you from his sinus infection. However, since you are essentially exchanging juices, he could have passed something else onto you as deteragram suggested. You should see your gynaecologist to be sure.
