If you can't remember, maybe it's time for an update. World AIDS Day — today — is as good a day as any to get an HIV test, and the web provides a number of search tools for finding free, anonymous testing near you (as well as AIDS education and safer-sex support). More options than ever are out there.
For instance, where I live here in LA, one organization offers free, quick oral testing (no blood! no needles!) in trailers that drive up to areas near nightclubs and shopping districts. The test strips taste sorta gross (in a pepto-bismol-meets-spackle kind of way), but you're sent off in a few minutes packing free candy, condoms, and the empowerment that knowledge brings. Wherever you are, periodic testing and a commitment to practicing responsible sex are a good thing.
