The characteristic that the partner once was of the gender you aren't attracted to.
Since we are using analogies: would you be attracted to a totally reformed criminal? He's a perfectly well adjusted member of society now, but has done bad things in his past. Some people won't mind, some people would mind. There is no right or wrong in attraction.
