Barebacking Colombian working girls
Actually, the prevalence of AIDS is higher in Colombia than the U.S., so you should feel just as comfortable barebacking prostitutes in the USA.
Also be aware there is a report on another similar mongering website, of a documented LDV girl who is HIV positive. The description was vague enough to fit many of the girls there. (Cute, curly hair, etc.)
You'll probably still dodge the AIDS bullet. I'd be way more worried about herpes, etc. You're really playing Russian Roulette there, no matter how clean you think they look on the outside...
