I've mostly shied away from dating. I did end up dating one guy for over half a year though. I knew him for a few months before we started seeing each other and broached the subject within a few dates. How I approach the conversation will depend on the circumstances, but I wouldn't date someone without disclosing my involvement in sex work. It would be too stressful/too much of a double life, and I don't feel that this is ethical. I do believe it's ok to date someone casually without disclosing, as long as you're upfront about not being sexually exclusive with them.
With my previous partner, I started the convo by asking if he'd been in any non-monogamous relationships, and how that had worked out for him. He decided that he was ok with me being a sex worker, and handled it very well. It was never a source of tension between us 🙂 We only saw each other a couple of times a week at most, excluding traveling together, so finding balance wasn't too tricky. When we were together I ignored work-related tasks, unless it was a quick confirmation text or similar. We discussed boundaries re: how informed he wanted to be about my work.
