I concur. There is ample evidence that men are judged on the grounds of height, that men and women alike are judged on body fat, and that pleasing facial features are beneficial irrespective of sex.

It seems likely that today's society is still guilty of objectifying women more often than it does men . . . but stating that every woman requires Sex Appeal contributes to that objectification in its own small way. It's part of the problem, not part of the solution.

Anyway, Sex Appeal isn't physical appearance, but a form of implicit bribery – just one where the implication is a service rather than goods. Sex Appeal is affected by Appearance, but that's a one-way street; Sex Appeal in no way helps raise effective Appearance. In fact, because it's generally inappropriate (see my comments upthread), it will often be at -1 to -10 and thus fail, resulting in a "Bad" reaction. That's the average reaction for someone with -6 in reaction penalties . . . like, say, Appearance (Horrific). In rules terms, then, going around using Sex Appeal is likely to have exactly the opposite effect of increased Appearance.
