I used to think that there were a few girls who truly enjoyed the work. But every girl I've talked to openly, in private moments, has had regrets and doubts. No one would choose this path if they had a better option (for the same money and effort, etc.)
The most striking example in my mind is a very popular MPA who excelled at her career; consistently stellar reviews, always marvelling at her complete devotion to great service. I recall one reviewer who said that she truly enjoyed men and another who thought that she epitomized what this industry is about. She doesn't regret getting into the biz, but she does think about how different her life would be if she hadn't. She knows that the biz messed her up personally, and knows that it has cost her a lot in her private life. I also remember clearly when she said she never wanted to get naked again for money. It blew my mind to hear all of this from her.
I also remember another legendary MPA who told me that being a sexworker is the loneliest job in the world. You can have the most amazing clients, who are considerate and thoughtful, clean and handsome. But after sharing the ultimate physical intimacies, being adored and flattered, at the end of the day, you're still alone. It leaves you feeling completely hollow.
