I eating with a HIV carriers travel together, hug! Later we happen to hand over, my fingers into his anus, later found him a small amount of blood flow! Probably my fingers when contact with blood in his rectum! My fingers and no obvious bleeding wounds or phenomenon, but was biting my nails is very short, I don't know if I have the risk even though some people say that refers to the risk free, but I'm not in contact with the blood rectum airtight environment? Ask you to help me to answer, I was going to be crazy, thank you for understanding my mood!
