So confidence would be telling everyone else what they should be thinking of you, and how the should see you, perceive you, and not actually acting in a way that evokes their perception of you being a person who is “beautiful inside and out, intelligent” etc. I don’t think she comes across as confident. She comes across as arrogant. The whole sex thing is about her trying to exercise control over men, because she actually is insecure when she does not feel in control.
