15 days ago I had sex with a woman that I found out after we were done was a prostitute. She performed unprotected oral on me for about 3 seconds. Then stopped and put on a condom. We then had protected vaginal intercourse.Within 3 days I started to have pain in the prostrate and penis. I started right away on antibiotics. I have been on the antibiotics for 8 days and the prostrate feels better but I still have pain in the penis, scared: also in the last couple of days I am feeling pain in the kidney area tenderness in my armpits and groin and I noticed white blotches in the back of my throat (thrush). Everyone tells me that the chances of getting hiv was very small. How could I have the hiv symptoms could something else be causing it?
