Free touch refers to the act of physical contact that is given or received without any expectation of payment or obligation. It is a gesture of affection, comfort, or support that is freely given and received between individuals. This can include a hug, a pat on the back, a hand on the shoulder, or any other form of non-sexual touch. Free touch can also refer to the ability to touch or interact with something without any restrictions or limitations, such as in a hands-on exhibit at a museum. It is a simple yet powerful way to connect with others and express emotions without the need for words.
