I find confidence terribly appealing... if a person can say what they are thinking, no matter how off-putting it can be at times, it's always a characteristic I find myself drawn to in others.
I am quite shy with men I do not know, but I don't think I am necessarily a shy person. I once was horribly shy, but it's been something I have been working at. I can be the loudest one at the party, or the quiet observer. It depends on my comfort level, and the more people I know, the more comfortable I am, naturally.
So when it comes to new people, I can come across as shy, more so with men than anyone... ESPECIALLY if they are attractive. I feel like a moron, jumble my words... but hey, i'd be like puddy in their hands if only they knew it.
put me in a room with 30 girls who are strangers, and I'll leave with 29 new friends (let's face it, there's always 'one' you love to hate)... do the same with a room of guys, and I'm likely to leave with less friends... or if things go well I'd just leave a little 'sore'.
confidence is something that can - and should be - built. I came out two years ago this coming August. At that time, I was brutally quiet, incredibly shy, practically a hermit, anti-social, lost, and barely... existing. I still have a ways to go, but I've come a long way.
One thing about being drawn to confidence when you are a shy person, is that being drawn to the idea of 'confidence' includes being drawn to that idea in yourself. You can't determine other people's actions, so you can't expect someone 'else' to do all the work and come to you. You are in charge of yourself, so that's what you can work on. As you become more confident with and in yourself... others will notice.
