Being "nice", "polite", "confident" or a general all-around "good" person doesn't create sexual attraction.

The "charismatic man" is basically a man displaying high social value. If your looks doesn't get your foot in the door, that's the only way you're getting in. By displaying alpha traits.

Whenever women refer to being attracted to a man's confidence, they are basically referring to his status. An ugly basement-dwelling loser with high self-esteem isn't getting his dick wet -- his confidence will be perceived as arrogance.

Confidence is perceived as such when backed up by success. Without the success, it's meaningless on its own. It's called delusion.
