While other STDs cause embarrassment, HIV causes tremendous fear. The situation only gets worse if the disease is left undiagnosed and untreated. And don't think just because you don't have symptoms you're disease free. You can have HIV for as long as ten years and still not show signs of it.

Any time you're worrying about an STD, you should also think about HIV, and vice versa. These days, testing for HIV is confidential, quick, accurate and easy, often involving no needles.

The effects of going untreated, not to mention the risks of infecting others, far outweigh any potential embarrassment. Get tested.
