Self-confidence is extremely sexy to a woman. In fact, I'd go so far as to say that, more than a man's good looks and more than his gentlemanly manner, confidence is the trigger trait that makes a woman want to get naked.
You remember that scene in Goodfellas when Ray Liotta takes Lorraine Bracco to the Copa? He slips her through the back door, tipping heavies the whole way, chatting up other wiseguys, and finally ending up at a table in front of the stage. Liotta had something much more important than a roll of Franklins: He had confidence. And its effect on Bracco was clear. You knew he was getting laid that night.
