So Sex With The Proper Stranger is like playing Russian Roulette with a 33 chamber revolver?
The headline is worse than misleading. The 3% figure must be modified by a sexual frequency figure. Homosexuals are thought to have sex more frequently than heterosexuals.
It would be if 1) the stranger did, in fact, have AIDS, and 2) you are a woman. Both of these must be true for your analogy to work. The title was not misleading.
