Thanks for reading, Sean.
Your thesis assumes that the only reason a woman ever puts effort into beauty is in order to arouse men. As a woman I can authoritatively say that this is not true. Certainly it’s not completely devoid of a sexual element but the fact is that women (speaking in very generalized terms) enjoy their own beauty for its own sake, not merely as a means to an end. Some men are capable of noticing and appreciating women’s beauty for its own sake without seeing it as a means to an end, too.
