We are all here for the basic reason that we relish human contact but as a relative newbie, is there a code of conduct to hugging? For example does the concept of 'spooning' take precedence over a straight-forward hug as time goes by? Does a difference in height matter? If you and a fellow cuddler were shoeless would that enhance the human connection or would you baulk at the prospect as your feet smell? Maybe it just middle-aged brain thats throwing out these trivial questions but who knows, perhaps others have harboured these questions?!
