First off, I have to say I like shy guys. I'm not all that excited about the idea of dating an "open book." I guess I like the 'chase' too when it comes to getting to know them. I understand their plight when it comes to making small talk, so I often take the lead when it comes to talking to help them feel less awkward.
Secondly, people often misconstrue being shy with introversion. I'm an introvert. When I was younger, I was shy... now, no.
Now, I just blatantly don't want to talk to you about mindless, pointless chatter. The art of small talk has been something I have battled with developing for years, and I think I've made decent headway. Though, at the end of the day, if I don't find you or whatever you are talking about interesting, I probably would not interact with you. It doesn't mean I am rude because I will acknowledge you, but I definitely won't be going out of my way to make you my new BFF which extroverts (at least the ones I know) claim to have in abundance. Introverts don't hand out friendship.
Thirdly, I don't think shy guys have "serious insecurity issues," let alone a personality disorder.
