Do you know any?
A few years back I worked with a very nice guy in his early 20s who casually mentioned to me one day that him and his friends would regularly go out, drink, take coke and hire prostitutes.
He seemed to be under the impression that, so far as unusual leisure pursuits go, this wasn't all that uncommon. But aside from this once I'm not aware of knowing anyone who's slept with a prostitute (although obviously many people wouldn't admit it).
So do you know people who've paid for sex?
