Wondering what the risk is of getting hep b from brief oral sex on a man I did not know. My regular dr is not concerned I went to my liver dr and he said we can test and he is 99 percent sure it will be negative I'm so worried I've been fatigued and it's been about six weeks from the oral I am also a man. So worried posted in hep b forum but then realized this was prob more aporpiate forum thank you
