4 weeks ago i received oral sex from one guy.I received oral In duration of 7min i didnt have even full erection.One week from exposure,i had my penis iritated,and colore of my urine was dark,so i decided to visit my urologist,and i was tested for Chlam.ghon.and ureaplasma -PCR,and all were negative.Sometimes i have some weird sensation in my stomach,and sometimes i get nauseous,its maybe because i'm constantly googling symptoms by the internet.So my question is,is there some chances of transmitting hep. B throw receiving oral sex,and do i need to be tested for Hep. B.Advance grateful for your response.
