I am not an expert on all AMPs, or other sex workers, but I have met enough women I have gotten to know well. And many of those have families, lives, and other activities of their own. Many have left on their own terms when they have met their needs financially, of found another option that is better for them. The ones that haven't left either feel this is the best option for them (financially, or working hours that mesh with school/young kids, or they just enjoy the benefits they get from their clients), or they have not done their retirement planning and fell they can't leave. Just like a lot of other people who are working at whatever their job is because they haven't prepared/saved enough.
But I also have seen up close some who have been forced either physically, through drugs, or through threats to family. Sometimes my real world job shows me the uglier side of this. That is one reason my preference is for outcalls with dinner. Most pimps/overlords feel uncomfortable letting a woman out of their control and don't. Plus I learn a lot more about a woman in that kind of setting, both from her conversation and body language.
Thanks for some good thoughts HardT. Out of curiosity, do you go by a different handle ending in "-T" on a different board? You sound a lot like him.
