Hiv and sti exposure risk

I had an exposure on 30th May 2022. I had a fling with a girl. It happened that I put my penis close to her vagina but I wasn't sure if I penetrated, and I I did it would be that the tip of my penis just touched the vagina opening as I didn't push it in, I thereafter ejaculated. Also the girl tried to insert my penis into her vagina and in that process my penis must have touched her vagina opening again. Two weeks later, I started having flu like symptoms, headache, cold, and some form of sore throat which was painful but was like something was blocking my throat, I had the scrub and spit it away continuously. A few days later I had swollen lymph node on my neck just down my ear towards the back of my head. I took malaria drugs and ciprofloxacin and I got relieved, but I discovered a form of rashes on my forehead, it was like acne (I will add a picture for reference). I also had muscle pain and tingling in my hands and legs. By July, I started falling sick again, this time it was so terrible that I had to go to a hospital where a test was conducted and I was told I had an infection, my white blood cell count was 11700 way above the normal count and I was administered a combination of sulfamethoprim and Trimethoprim after which I took and I got better. I again used Ciprofloxacin and I started having the same acne like rash on my forehead again. I later noticed that I was always feeling so hot in my neck and chest area and if I used a thermometer to check my temperature it was always in the normal range of 36/37 degree celcius. I would like to know the following n
1. What are my chances of contracting hiv under such circumstances like my exposure?
2. Does the discription of my rash looked like hiv seroconversion rash?
3. Does my symptoms align with ARS symptoms?
W
4. Could I have been infected with another STI other than HIV
