For me, the personality will determine if they are attractive or not. My mom once asked me if the cable guy was handsome and I couldn't tell, I just remember he had 2 eyes and a mouth and seemed tired of his job but according to other people he was, I don't know. If I really don't like their personality I will find them ugly and repulsive, if I really like their personality, I will find them attractive. I'm usually not interested in relationships, no matter how the person look, I may change my mind later if I really like the personality.
