Speaking as an older guy that spent a lot of time in the military and has been around the world several times, some of the prostitutes do enjoy sex with some of their clients and not others. Some of the prostitutes do strictly for a job and that is all. It just depends on the individual. It is legal in the state of Nevada on a county basis and is strictly controlled as to health and kept out of the hands of criminal underworld. Many of the girls are students at college and pay their tuition that way. This is probably more answer than you wanted. So - Some do - Some don't.
