As a kid I stopped "enjoying" hugs when I understood the nature of deception (about 5 years old). That's also when I started pretending to pray (I would count time in my head in church. A savant in that manner, I can always tell what time it is without a clock, even if I'm piss drunk or awaken in the middle of the night). It wasn't until I joined a dance ensemble after my post suicide attempt hospitalization, that I got more accustomed to physical closeness in that respect (everyone was hugging there, males and females would dress and undress in close spaces. Relatively low degree of intimacy altogether, since during a performance you often have mere minutes to change into another costume and people have to help each other out as best as they can). This helped to desensitize me to unexpected proximity of other people. I still find it uneasy though, as I'm not always certain what the underlying purpose of the hug is.
