As a cuddling enthusiast and lover of platonic touch, some of my favorite moments of human physical interaction have been moments when someone cupped my hand or put their hand on my shoulder even for a second. I think those moments often do a good job showing how much one cares and almost always feel super warm and emotional in spite of their "low-key" nature, and in my opinion, we should emphasize such "low/key" touch much more in cuddling, whether professional or mutual in nature. Maybe even in everyday interactions too since very non-taboo!
I think the awesomeness of hand and shoulder touch relates to an important principle in cuddling that understands the importance of restraint and even deprivation whereby the imagination fills in the blanks after one is given a taste of physical affection... the joy of cuddling is as much in the mind as it is literally in the body after all. The momentary and limited nature of a held hand or grasped shoulder via their restraint as gestures... but also via the suggestion of possibles... can inspire waves of warm fuzzy feelings in the imagination that tingle throughout the body as well as the appendage of contact and be as satisfying as some of the more involved cuddling positions.
This may just be my experience, however. What are your thoughts?
