Don't get me wrong, it's not like I can't stand being hugged.
If I haven't seen a person I'm close to in a long time, they often get a hug. And the nephews and nieces are always crawling on me and cuddling, but they're kids. In my strange mind, physical contact is a very important and private thing, used in cases of comfort and encouragement. I don't share it with everybody all the time because it feels untrue and awkward. If that makes any sense.
