1. Have your HIV test. No one likes bad news, but ignoring something that may already exist only makes your health get worse. More guys survive with HIV today because of early diagnosing and prompt treatment.
2. You likely do NOT have HIV, if you had safe sex. Remember, safe sex means treating EVERY guy you meet like he's poz. You may have some other form of infection, affecting your glands and/or lymph nodes.
3. My partner & I are tested, by the same doctor we share, every few months. Trusting each other to be 100% monogamous, 0% fooling around with others, and having tested negative for years, our HIV risk is virtually nil.
But we test often and share the results as a mark of good faith, since each of us has encountered, or even had, cheating partners in the past who got themselves infected. Plus we work with the HIV/AIDS community, and so we test frequently to set the example of what we preach to others to do. The message being: if we who essentially have no risk at all get tested, then YOU get tested, too.
And BTW, smart move that you've already been tested once, and have planned to do it again. Don't get cold feet, OK?
