Excuses me, I had a cunnilingus to a sex worker (maybe just 2 second), and have a protected sexual intercourse with condom 10 days ago. However, I am so worried about that my oral ulcer and tooth cavities (I have filled my tooth at that day morning) were expoused to the HIV virus that can make me infected. I wonder if I am at risk? Need I go to hospital to have a blood check?
