I think when a guy or girl flirts with you with confidence, it means that they are confident in their attraction for you and not worried about a possible rejection - now, that is an awesome turn-on. It used to make me think that there was much more to that person than met the eye. That's why I married my husband - it was his confidence. He's a thin, only average looking guy who programs computers. We've been married for over 20 years and I'm still impressed by his swagger. He reminded of Yule Brenner when he was at the pinnacle of his acting career. No real looks but a masculine confidence and sexy swagger. Irresistible. Good, confident voice too.
