Hello! I have had several encounters with people of known (now, not at the time) HIV positive status which has included deep kissing and minimal unprotected oral sex (both the giver and the receiver). I am only the top when I have anal sex and have never had unprotected anal sex (I always use a condom). I have never taken body fluids and may only possibly have taken a minimal amount if providing oral sex. This has all been within the past 2 1/2 years. I have had lots of changes to my body since then - more headaches than usual, random thinning around my nose, jawline, and forehead, hard and more pronounced salivary glands. Really, I haven't felt my 100% self. Sure, maybe this could just be "in my head", but realistically, what is the chance of exposure and a test showing up positive?
