As part of who I am, we have cuddliness... I like physical closeness, neareness, touch, hugs, cuddles. It's a way of expressing myself, a way to be social (I've often said "I'm cuddly with my friends"), a way to be loving, at the very least with those that are emotionally close to me.

Make no mistake, it's not all that I am, but it's part of what I am, not easily separable from the rest.
There are times when cuddliness iss unwelcome, even by close ones. And observing myself, I can see that it's difficult for me to turn it off. I can, but many times, more than just the physical gets turned off. I become a bit more distant, and that might not be what's desired, certainly not by me, and probably not with others.
