The test for gonorrhea and Chlamydia is really simple; all you have to do is pee in a cup. (Another way to test for these sexually transmitted infections (STIs) is a swab of the cervix, similar to a Pap test.) The test for HIV involves pricking a finger for a few drops of blood. You can be tested for HIV anonymously. You can also buy the home HIV test Oraquick. You may want to be tested for other STIs depending on your symptoms; talk to your doctor about whether other tests are a good idea.
