How has the use of prostitution services evolved historically in North America and Europe?
Compare to the past, what percentage of the male population has used the services of a prostitute? What about the frequency of use for those who do? If there have been sudden permanent changes, when did they occur?
Historically, is it true that sexual practices like fellatio were common among prostitutes but not among non-prostitute women? Were there others?
Was one of the argument against prostitution that non-prostitute women felt like they had to compete with prostitutes? Or that sexual practices like fellatio were dripping into married sexual relations?
I know it’s many questions but if you only have information about some of these aspects, it’s very much welcome.
