If the condom did not slip off inside her, you had NO RISK FOR HIV. That you were withdrawing from her and the condom was half in/half out means that the head of your penis was covered at all times and that is the ONLY concern. NO RISK NO NEED TO TEST.
As for your physical symptoms, they sound like a bad cold or possibly the flu, but they are absolutely NOT related to ARS. Most likely they are triggered by anxiety. See a doctor if the symptoms don't go away in a week or get much worse.
You're OK!
Sorry to disturb you again...this is will be my last question.
I am also getting white patches in mouth (inside cheeks and lips). Could it be the symptom. I really very scared if I accidently touched her vaginal fluids with my inflammed penis. Scared to get tested...
Actually I am suffering balanitis from long time. Does having active balanitis changes the risk in my scenario. Please suggest.
