A little over 6 weeks ago a gave unprotected oral sex to another guy. It was for not very long at all. There was no ejaculation and I don't think precum but I am not positive. I know oral sex is lower risk, but I am really worried because I know he has had unprotected anal sex with other men. At just about 4 weeks after there were three nights in a row that I felt very hot, radiating from my head. I didn't take my temp until the third night and didn't have a fever. I have never really "felt sick" and didn't have any chills or body aches. I was even out drinking alcohol during a couple of those nights. Then over the next week and half I got very hot two random other nights. Every time, it never lasted more than a couple of hours. I can't know for sure if I ever even had a fever. Does this sound like a fever? Is it likely that they would be so short lived? Does a fever usually really knock you off your feet? What do you think my risk is and I know symptoms vary and some people don't have any but does this sound at all possible similar to symptoms of ARS? I am going to get tested soon and again at three months. Please help. Thanks you!
