I know what you mean. The two weeks when all of my snuggle-folks were away at Burning Man made me crabby, and then when everyone returned I didn't know how to tell them that my skin hurt from not being touched.

Re: sleep and snuggles - I like to sleep in the same bed with someone, and not snuggle to sleep, but sleep near each other, with a limb touching. Once in collge my boyfriend and I fell asleep with our hands intertwined across the space in the bed. It was so lovely.
