Dear H. Hunter Handsfield, MD
First please excuse for my english.
I just performed oral sex for my online friend, she had a husband who is drug addict. When I performed oral sex I had ulcer in my mouth (in final stage, I feel almost no pain) and I brush my teeth after having sex with her. If she was hiv-infected one, what would be a possibility of hiv transmission in my case. Do I need to take PEP (I was told that it should be taken within 72 hours after unsafe sex)?
Please help me and reply me soon.
Thank you for your time and your help.
