I agree. It's none of our business and I usually don't inquire about personal things unless the gal in question volunteers "her story." I first got into the hobby in the late 80's while in college; took an extended leave of absence for grad school, marriage, kids, etc. After my divorce I resumed and got to know a number of these gals personally. One gal in particular who became a very close friend until her suicide in 2014 told me a lot about herself and various gals in the biz whom she meet. In virtually all cases, it always initially comes down to a need for a lot of money to pay off snakeheads, G-card hubbies, etc. The "life" often leads to a lot of gambling, substance abuse issues and/or shopping addictions among these gals, they just stay in it until they burn out, find a guy to support them or get too old. Some are able to exit with some degree of grace and independence by saving their money and starting a successful or at least sustaining legit business. Some get out and start businesses that fail and then get back in. The money is "easy" in the sense that a busy gal, even with C-town "discount," can gross $300+ a day, cash. It's hard to imagine Lily or any similarly situated gal making the same $ doing anything else. But for most, the job is a grind physically and emotionally.
My friend who committed suicide was probably the best person "built" for the job, meaning that she truly loved having sex with different men whom she found attractive but she found 80% of her clientele to be at best, boring lovers, and often disgusting ("too old," "too ugly," "stinky feet"). My friend managed to be a successful indie and saved quite a lot of money and was able to buy several rental properties. She avoided the usual pitfalls of drinking, drugs, gambling, etc. However, she was very likely bi-polar and her untreated depression got the best of her.
