You're good: If your test was one of the modern ones that includes both the protein and the early antibody, it is almost always positive by this time. Since you're a grown-up, I urge you to get a HIV screen once per year like the rest of us, just as a gentleman. If you're going to do this -- and you're fine -- please talk with the other guy first about his own status, and with your physician about your options
