I have gum disease. Lately, my gums have been bleeding only when I brush my teeth. I recently gave oral sex to a person, in which I did not know of their status. I had brushed my teeth at least 1.5 hours prior to the oral sex, and I did not see any blood after the act itself. I did not swallow the ejaculation, I actually spit it out. I also did not immediately brush my teeth after this. Am I at a great risk, if any, for HIV? Thank you for all of your help and advice.
