Hi dear doctors, I am so sorry to post a repetitive question for you but I cannot hold my anxiety. A few months ago, I performed oral sex to a South American guy’s penis for about 15-20 seconds. I didn’t feel his pre-seminal liquid but I am not sure if there was any. Moreover, I am not sure if there were any cuts in my month. I didn’t experience any acute-period-like symptoms, like fever, pains, rash...to my best knowledge. And I posted a question here and got the advice “no risk” so I calmed down. But, unfortunately, I did experience an horrible anxiety and depression for A LONG TIME imaging how scary my future would be if I had been infected the virus... but after rational thinking I could always calm down. However, these days I am expericing a very strange pain, which is always “moving”, sometimes at my fingers, sometimes at my left hand, sometimes at my knees....but only one place at one time. I got the advice from my friend, who is a doctor in my city in Japan, that longtime can cause subtle pains and it’s not unusual... but I dare not to tell him that I had sex with a male when I traveled to South America. I am so scared now and expericing the worst anxiety since I was born...please reassure me that giving oral sex to a guy, maybe with pre-seminal liquids, maybe with cuts in mouth cannot be a mode of transmission of hiv.... thanks for saving my life...give you my best respect!
