Touch is a dialectic: touching the world defines the self. In touching something, 2 things are affected: the object touched and the person touching. Touch is an interplay between the object of experience and the sensation of the experience.
Pleasure and pain are interpretations of touch. Those interpretations define what is touched and how.
Associations define the self. Associations are by definition what is touched and held and what is not.
At the most intimate level, a human conveys to another person meaning via touch. In those moments the nature of self is revealed.
The touch of desirous love is the epitome of emotive tactile sensation, for both giver and receiver; though sometimes, love is expressed in what is not touched.
