Further, localized yeast or other fungal
infections --
of the penis or anywhere else -- are not a sign
of HIV. Such things occur all
the time in perfectly healthy people. Your other symptoms (sore throat, runny nose, etc) almost certainly are exactly what they sound like: you caught a cold.
And you had a negative HIV test. I can't tell exactly how long after the new sexual contact you were tested, but Lizzie Lou (on the HIV community forum) calculated it as about a month.
