around feb.3 i had unprotected sex with this girl that says she doesnt have anything or ever had unprotected, but i think she is lying. but like two days after sex i felt the tingling pain in my penis like on the top. that pain is gone now but i did some research on stds and i feel like im going threw those symptoms. i recently had headaches and been light headed for about two weeks i think. i been lacking an apptetie and feeling nausea sometimes. now i think im developing some stuff on my skin and i think i sweat in my sleep. but i been tested for syphills, gonherrha, calymida, and hiv. all the test came back negative. the last time i got tested for hiv was either on march 6 or 7. and i have crabs that just dont want to go away even after i tried a recommended product subscribed by the doctor called lindane. so what should i do doc.
