The two are not equivalent. the verb “touch” implies some will, consciousness, deliberate intention on the side of the subject. The hand is then turned into such a subject, an individual. It has its own will and objectives. Whereas “you” is obvious endowed with will and intention and thus that touching is not innocent on “your” side. This second phrase then implies there is something sexual in “your mind.” Whereas there cannot be anything sexual in the hand’s mind because the hand does not have a mind, or then we are entering fantasy and fairy tales.
