I think maybe you see porn and the production of porn as something a bit more glamorous than it really is. I doubt that a girl who has just done a porn scene where a guy has spit on her and throatfucked her, drenched her in cum and maybe even slapped her, sees the "actor" as a friendly colleague she can joke around with after the scene. And from what I've heard a large percentage of the girls in porn also work as escorts in addition to porn, so they are fucking guys they have just met and are what most people would call whores. But there is nothing wrong with being a whore. Its a "career choice" ALOT of girls make every year.
I have not mentioned this before but someone I went with in my early 20s was later a major porn star in the 80s so I think I have some idea of what motivates at least some of the people.I never said it was glamorous, what I said was it is acting just like the acting in regular movies.Some of the people who do mainstream movies together are not friendly eithier.These people do it for money and then go home, and what I said was they are not usually the same people at home you see in the films.The girls who are living life hard and fast and hooked on dope or whatever and there are some in the biz usually burn out fast.But I would also add that porn thrives because of all this puritan morality around about sex and it being dirty and women being whores.How big porn is says as much if not more about us the the viewers then it does about the people in the films IMO.
And yes some work as escorts and again its all about the money.I'm fine with a woman using her body to make money if thats her choice and would not think she is somehow lacking morals because she does,but then again I think what most people consider to be important as far morality goes is a little skewed.Lots of things in the world more immoral than getting paid for sex,but thats just my opinion.
