"I think it goes back to the physiological underpinnings of such an attraction," Rupp said. "For instance, testosterone is a hormone that in men is linked to more dominant personality traits -- outgoing personalities and charm and things like that. And men with higher testosterone are rated by independent observers as being more outgoing and charming than others."
Some experts, however, believe that these narcissistic males tend to embellish the self-reported tales of their own sexual conquest, leading others to believe they are more sexually successful than they really are.
"People high in dark triad traits tend to say what they think others want to hear," said Everett Worthington, professor of psychology at Virginia Commonwealth University.
Moreover, Worthington notes that while some of these males may be more successful at short-term sexual relationships, their overall success with long-term relationships is often compromised by their dark triad traits.
"The manipulative 'It's all about me, so tell 'em anything to get sex' behavior is likely to have more short-term sexual success," Worthington said. "A strategy of building trust and intimacy and commitment is, by nature, going to take longer. Thus, the payoffs are likely to be greater in the short term. However, long-term relationship survival is likely to be strongly disadvantaged in people with dark triad traits."
So maybe good guys don't always finish last.
