I hate it when people touch my things.

No problem, everyone will do this, but some are sensitive and some are not. Pajamas, bowls and chopsticks are all personal belongings. How can this thing be used on people? For example, if a stranger wears my pajamas, I won't wear them again, but my mother does, and I may wear them after washing. You don't have obsessive-compulsive disorder, but you have a strong sense of self. Just accept yourself. Don't be too entangled. There is nothing wrong with having such a habit. Tell your family frankly and let others know that you have such a habit. I don't like to be touched, used casually or collected by myself.
