It's sad that some people will go through their entire lives thinking that nudity's only function is a sexual one. Think of all the opportunities that will be missed, to enjoy the feeling of freedom that comes from being unclothed - alone, while not engaged in sexual activities, but especially in the company of platonic friends. Think of the artistry, and the beauty of the human form, that will go unappreciated in life, because every instance of exposure is interpreted purely in the context of the pursuit of sexual gratification. People are terrified to even glance at specific parts of other people's bodies, assuming that such anatomical knowledge is reserved for a sexual relationship. In the fitting room. At the pool. Lounging at home. We bend over backwards to make ourselves uncomfortable, all on account of an arbitrary taboo. Think of all the art, the entertainment, the humor, that will be passed up, written off, and ignored, treated as nothing more than simple-minded pornography.
I'm not saying it's wrong to enjoy the erotic appeal of the human body. I'm a passionate advocate for sex-positivity. It's not either/or. I just want to emphasize how much further the virtue of nudity extends. If you only ever get so far as to recognize its sex appeal and stop there, you'll be missing out on so much. Nudity can be an element of fashion (it sounds counter-intuitive, but it's really not - after all, you can't change clothes without getting undressed first); it can be an element of fitness and athletics (as in antiquity, and the original Olympics of ancient Greece). The human body, properly cultivated, has the potential to be a shining beacon of joy and inspiration in our frequently dour lives. If you only ever allow yourself to indulge in it in a sexual context, limited to a few private relationships, you're excluding yourself from so much pleasure and happiness. But it's not just about you, because this belief shared by society prevents other people from experiencing that joy also.
