I had a protected vaginal sex with a prostitute before 2 weeks, and because it was my first time I ejaculated immediatly after the penetration, and stayed inside her while she was on top of me for around 15 seconds, then I pulled myself out and the condom didn't break, and she leacked my nipple also. After 11 days I started feel nasal congestion then my temp raised reaching 38.5. I did a cbc shows Ly 14.9 L, Gr 81.5 , wbc and others were in the normal ranges. I am afraid that this flu may related to that sex and I started concern that I may got infected with HIV. Should I concern about that? Please help me!! Its my first and last time ever.
