My husband has a strange hobby and likes to scratch my feet.

The situation you are talking about is a psychological phenomenon. Some people think it's a mental illness, but the client often doesn't think so, and he doesn't want to see a psychiatrist. At the present level of psychological medicine, it is possible to correct it only if he is willing, otherwise there is no way. What you said is relatively simple, and there is still a lot to say. You need to know how this affects your life and how your daily life is. You didn't give contact information, and you can't be too detailed on the public platform. If you want to discuss it further, please ask questions.
