Well, some people put on a stiff upper lip but *inwardly* crave for a hug or just to be held... just because of some 'deprivation' in that area. But due to said 'deprivation', it does then feel awkward if/when one is actually hugged. I imagine it could also be the case if there was no 'feeling' behind the hug when one experienced it (as a child) - i.e. if the hug was merely an automatic/mechanical gesture. Dunno if that makes sense.
