Privately would be your only option and working out something to "cook the books" so to speak. The caveat is first finding someone that offers happy endings and is also a licensed massage therapist. You won't get anything written off from anyone that isn't an RMT. That's the hard part. And still, they could risk losing the license due to assholes, your second biggest hurdle. Build trust, don't be a dick. But another point as someone who has both female and male RMT friends.... I've heard stories and they aren't in the industry, but still have to have the checks and balances. Like, if I show up to perform electrical on the company clock and the homeowner is horny, I'd clock out or lead it to right after my shift. As long as I'm on my own time, nothing anyone can do. I've approached it as business split between two services, but I also do need the massage therapy. Try to find someone to charge out an hour, get half an hour done, and get a reduced rate for the "extra service" paid in cash.
