Confidence is never having to say "Was it good for you too?"
For me confidence is not being reliant on other people to give me my self worth. Someone may think I'm an ass (and a great many here do) but it means very little to me as I don't require their approval for my own self esteem.
So in dating as a male, this means the woman knows you don't need her. You may like her but if she doesn't respond she knows you will shrug it off and move on. This seems to trigger their own insecurities and then they try to make you want them. Almost no woman likes a guy who seems needy no matter how nice is he.
To much self confidence can be bad too but thats another topic
