My last encounter was about a month ago, but i never went inside the girl. But since then i started experiencing some tenderness from the nodes in my groin and neck. I also have experienced some pain in my sides, unusual fatigue, whitish tint on my tongue, sore throat. I did get tested and the results came back negative, but that was only 2 1/2 weeks after the incident. I've been pretty worried its all i can think about.
You don't have HIV. You likely were just sick.
Only way to know is test now, then 3-6 months again. Do it, be fearless its your body and life. Better to know yes or no now then later.
