I guess it is easy to get confused reading conflicting information on the internet. The CDC says there have been cases of HIV spreading through protected anal. Like I said, I was the top and I had nicked my scrotum earlier that day. It scared me that fluid during anal sex got into the nick. I usually never get sick, especially during the summer. I have a fever (100 degrees), body aches all over and diarreah. I don't usually worry this much, but I am definately sick with something.
You were never at risk of contracting HIV.
