Even if they are also enjoying themselves, a sex worker is doing a job. They are there to make sure their clients have the experience they want. An actual relationship is (hopefully) more balanced where the person feels fine about asking for what they want as well. The high end gigolo I knew would not do dates longer than 24 hours (some escorts will be available for travel or several days) because it was just too exhausting for him to be present for his clients in the way he wanted to be for longer than a day. I know you know this stuff — I’m saying it for others who might not. Sex work is work. It’s a job. Being in a relationship is not. It’s a different thing, regardless of the money aspect.
