I'm extremely shy and asocial...but play a game against me (especially a fighting game), and I will happily trash-talk you, myself, the characters, and fate in general for hours on end. I'm starting to think that I'm not so much asocial as I just don't trust myself to be social, unless I'm in very controlled circumstances (business, usually) or until I get distracted by something.
Also, I tend to not notice things that would impair my enjoyment. I don't think I'd enjoy, say, Kodomo no Jikan so much if I really realized just how much of the lolicon I subconsciously ignore...
