At the end of the day, they're both fucking for money so I can see why its hard to differentiate. But there are differences between both careers that would separate the two. One- prostitutes are providing a service for ONE person, and pornstars are providing a tangible good for countless people. They are entirely different careers in most aspects of it. Penis inside vagina shouldn't dictate what your career title is, because every other aspect of the careers are different.
Is a fireman the same as a paramedic simply because they both save lives? I don't think so.
Is the porn star "providing a tangible good for countless people" or is the production company providing that good?
Here's a closer ANALogy:
A bikini model is paid to do a photo shoot, only the model and the photographer are present and the photos are not sold and only used for the photog's portfolio.
Another swimsuit model is paid for a photo shoot with the photographer but this time the photog sells the photos and the photos are published in the Victoria's Secret catalog.
Were they both models?
Did THEY, the models really provide a different service?
OR, did the photog have a different use for the exact same service rendered by the models?
My point is; can the use of the exact same service provided be the determining factor of 'different' professions. OR, is is merely a title change?
What about all the movies and or scenes shot that never made it to tape for whatever the reason....lack of funds, lack of distribution..etc.
Did those "porn stars" featured in those scenes now perform the duties of a prostitute because the sexual act was not shared with millions?
Honestly, you can't really re-package this....only put a spin on it.
End use for services rendered does not change the service you provide.
P.S. -
Firemen and paramedics perform entirely different duties. Saving lives is a byproduct of the duties they provide.
