Let's look at the grand total of all AIDS cases reported in history to the CDC and how people got them:
http://www.cdc.gov/hiv/topics/survei...c.htm#exposure
60% - getting fucked in the ass without a condom
22% - sharing needles
9% - not sure because they were sharing needles AND getting fucked in the ass without a condom
8% - hetero sex (although also often anal) with someone known to have HIV
1% - blood transfusions and other sources
OMFG, bare-backed by a hooker? We have a winner! You're the highest risk category on the planet to get AIDS!
But that's common sense, isn't it? Are you sure you're not bug chasing?
