Hi everyone, I'm a 20 year old male. On the 21st of August I had a one time unprotected oral sex from a random female I met online. I had no visible symptoms but was very anxious about catching an STD or HIV. After 3 days of intense worrying, I started to have pins and needles in my hands and went to the doctors for a check. The doctor also told me they were due to anxiety. The next day the pins and needles were gone but I was still in constant worry. My palms were also reddish(flushed red). After being anxious out of my mind for 2 weeks, i went for a urine test and hiv rapid test at a sexual clinic. The test for STDs(gonnorhea/chlamydia/syphilis..) and HIV were all negative. To date, I don't have any pains/symptoms when peeing or at my groin area but my palms were still slightly reddish and i had headaches and diahhrea for about 2 days. I read online that red palms, diahhrea and headaches were symptoms of HIV hence I'm still very anxious about it. Can someone assess my chances of getting HIV and STDs from this one time unprotected oral sex? Thanks..
