Speaking as someone in her 50s, I would advise you to think long term.
A good education and career will stand you in better stead than any short-term money earned through escorting. In terms of not lying to family and partners, getting a mortgage, gaps on CVs etc., I would always recommend focusing on civvy life, and just escorting on the side (and using the money earned from it sensibly, i.e. saving, buying property etc.)
I'm not saying escorting isn't a feasible long-term career, but it comes at a price, and with a lot of hassle, and it's difficult to predict the problems it could throw at you down the line.
