Arggh I forgot one of those basic rules, probably the most important of them all. It's so deeply ingrained in me I don't even think about it now.
Keep your work and private life separate. If I let my work into my private life I will never get it out. I go further than most possibly, but I have two sets of clothes, make up, lingerie, pretty much everything, work and private. And they don't mix. If I use it for work, I only use it for work. Though it's exceptionally unlikely to be an issue, I'd never take as a client a person I know in my social life. Likewise if I should run into a client outside of work, I would treat them as a complete stranger (this is also part of discretion, they appreciate it). I do care about my clients, hard not to most are nice guys, I never let myself or them forget I'm a sex worker and they're my client. You blur those lines, you're lost.
