It makes sense to me that some people can't identify what they are feeling, or why.
I have heard the term "skin hunger" and didn't think it applied to me, since I seldom want a hug and feel uncomfortable if it goes on longer than a few seconds.
But I actually do have tactile needs, which are met by curling up under the covers, wrapping them around me, hugging the pillow. I remember we had a visit at work
one day, years ago, from a recently retired co-worker of whom I was fond. She hugged everyone, I didn't particularly mind, but afterward another co-worker observed
that during the hug, my hands looked like claws.
She asked me something like "Now, didn't that hug make you feel better?" and I had to admit...no.
It really did nothing for me. That was a really educational day for me; it gave me insight into the difference between me and a lot of the people I know.
