Hi doc. 2 months before I had a fail Sex with spa worker. Location dubai and girl from Vietnam. I had protected fail sex (penis not erected so did not penetrate). But had unprotected oral sex where she gave blow job to me. After 2 weeks I noticed the bump on my penis which I consulted with doc. Where he made me more confuse and tensed. Although I tested for VDRL which comes negative on 3rd and 7 th week. I tested for HSV which also negative on 7th week. I tested for hiv as follow 3rd week 4th gen antibody test: negative. RNA on 5.3 week: negative. Antibody and p24 antigen duo test on 5.3 weeks: negative 4th gen again antibody test on 6th week negative. Now my doc says I do not need to take tension and it was not even syphilis. Im so confused and scared still now. Which test I should go with to test accurately now after 8 week.
