You could tell him you don't offer massage anymore because it causes tendonitis to flare up in your wrist.  Or something like that. Otherwise it just depends how much you need the money really.

That won’t work if he checks the ad.

Some men repulse me and I won’t see them again, yet some escorts see these men and give them positive feedback. You have certain standards- he can’t help some things but other things he can.l Don’t feel guilty !

I had a client like this in Leeds he was about 20 stone and when he came out of the shower he had not washed and I could smell cheese and onion on the large folds of his stomach. That coupled with the fact he had no teeth and was the most revolting man I’ve ever seen. He was like I wish you did kissing. Not a fucking chance. I’m never seeing him again I would rather loose the money than put myself through it. Very obese men I can’t tolerate it.

Normally, I’d suggest being honest and straightforward when something’s bothering you. But in this case, since he was a good client, it might be kinder to come up with a gentle excuse not to see him again, just to avoid hurting his feelings. That said, it could be tricky to pull off. Another option is to simply say you’re busy whenever he tries to book another appointment, he’ll likely get the hint and stop reaching out. If he’s persistent, then at that point, it’s best to be honest with him.
