Is there a condition where you have to make bodily contact with others?

I didn't know exactly how to word that, but I'm just curious, is there some kind of condition where you have to make contact with someone or else you get kind of awkward/depressed, or some other kind of thing? Or is it just something people do? Like, you have to hug someone constantly, or hold hands with them, things that show affection -- even friendly affection, though.
