I wouldn't be so sure about that - the greatest womanizer I've ever known is a lanky, almost scrawny nerd with curly hair. What he lacks in looks he more than makes up in his personality - he's the life of the party, knows everything about everyone, a master socializer... etc.
He's a shoot first ask questions later sort of guy - will never betray a moment of doubt, I think that's what makes him successful at both life and women.
