Dears HIV community I really appreciate your opinion on my situation, I am MD student from Germany I had a single protected vigianal sex with a CSW wile I was in Berlin 3 months ago, the sex was very short just inserting and puling out immediately, I told my doctor ( my brother MD doctor ) about my situation and I asked him about test laughed at me and told me condom protected inserting and puling out is not even a real sex, any way he draw blood from my vain for test 8 weeks after the exposer the test was negative ELISA antibody only he told me its conclusive for my case and he told me also I need psychological help since I have hard time to move on, please I need your opinion do I need retest if you guys tell me I am ok I will stop worry since my brother laugh at me and tell me I need pregnancy test as well (very rude of him)
