One of the things my wife loved about that work was reaching out to people who were lonely. She often talked about that aspect of it.
LR, she also said that it was a blast! After a similar number of years, she did get kind of burned out on it, though. Most folks were nice enough, but those that weren't were really bad. And you're right, it's hard to keep your head straight sometimes, and lots of women in that business don't seem to be able to manage it. There were a lot of alcoholics and drug addicts, or just people who were messed up in other ways. Those that had their act together were the rare ones, and they usually had kids.
Interesting comment about there being many poly people in various types of sex work. She saw that too.
