depending on your resources, you could go to Las Vegas where prostitution is legal. then you will be better able to determine whether the prostitute actually has a pimp (not all of them do).
i read an article in a magazine (SciAm Mind) and apparently many Johns pay for the conversation and the connection, not as much just for the hookup.
that's about it. also wanna say i love Depeche Mode too!
great lyric choice.
