Hi, I had unprotected sex for 3 mins with a gay who was fit and fine but his hiv status unknown. Were no serum come from his private part and nothing touched my private body. Still I had done elisa test on 17th day which was negative I have no symptoms of hiv except gas problem. I consult the doctor as I had gastroline problems he said I am not suffering from any disease. I am still worried am I affected with hiv?
