There are several misconceptions about what it means to be an escort and it might not be safe disclosing information about this part of your life. There are so many friends and family interested in knowing what is going on with you and it might feel like betrayal when you have to deceive them but often, it's for the good of everyone.
One way to keep your secret is by maintaining a safe distance from your mundane life. Research your clients as much as you can and make sure they don't roll in the same circles as people you know. If possible, only engage in activities outside of where you reside, especially if it's a small town.
Have a good explanation for your income because people around you will get suspicious if they see you living above their estimation of what your day job wages or other allowances should be. Get a socially acceptable side hustle that doesn't have to earn you much but give the impression that it does. Be creative.
This might seem like a no-brainer but getting a fake identity is necessary. Just a fake name might not be enough. This not only prevents family and friends from finding you out in this current world of online connectivity but it protects you from predatory clients.
Never spill even when you think the person can be trusted. Why do you want to share your story with another person when you know it may not be the best thing for you? Because secrets are hard to keep. If you can't hold your tongue, what makes you think the next person would. It's not a secret anymore if someone else knows.
Be "normal", perhaps even prudish. Try as much as possible to look like the picture of virtue (except with people close to you). If someone finds you out and spreads the tale, it would be met with rejection by people around, contrast that with a persona that already gives them cause to suspect.
Keeping your circle as small as possible is crucial because this gives you more time to go about your personal endeavors without people wondering where you are. It also means there are less people you engage in intimate conversations with, where you are liable to divulge information in a bid to keep the relationship honest. Chances of running into an acquaintance while on a job are also lower.
Try to be available to the people in your life so they don't start looking for ways to explain your absences. This is harder than it sounds but it is the reality of the situation. If you have children or other people you live with, give them enough of your time so that their curiosity would not be aroused. There is no need either to destroy good relationships with people if you still want them around.
You have just yourself. Take care.
