I am a heterosexual woman. On october 7th I performed oral sex for about 30 seconds on a friend. It tasted soapy like so I stopped. Then I sat on his penis with out protection. I got up before things escalated to a full sexual encounter. I noticed the next day my mouth felt weird. The following Monday I went to the doctor. They said it was a bacterial infection. Swabs were done of my mouth and vagina. All came back clear including a HIV, negative. The infection is still present however, ibhave taken two additional HIV test. One at the 5 1/2 week mark (finger prick) and 10 week mark ( oral), both were negative. Can I believe I'm HIV negative and it isnt causing the infection in my mouth. I have not had any oral sex since then.
