Holly of The Pervocracy on the problem with beauty standards. You should read the whole thing. Here’s a snippet.

Individual preference isn’t the only problem with standards. The other problem is that it’s really unhealthy to create the idea of the perfect mate in your head and then try to find humans who match. I didn’t know that short blond men were sexy to me until I met Tommy. In fact I still don’t know that they are—I just know that Tommy is, and I think a tall dark Tommy would appeal to me more than a short blond random guy. We don’t live in a world of types but people.

So “standards” suck, but that doesn’t mean everyone has to find everyone equally attractive. That’s silly and it’s not going to happen. Plus it leads to creepers going “you can’t find me unattractive, that’s discrimination!” This also doesn’t mean that “everyone’s got someone”; the vast majority of people do but I can’t make you promises. What it really means is that sexiness is the chemistry between individuals. “Society” isn’t going to date me no matter how thin and busty I am; the intersection of one person’s unique appearance and one person’s unique and malleable preferences is all that ever matters.

Asking if I’m “sexy” is, ultimately, like asking if I’m “a friend.” The answer isn’t yes, no, or even “depends by what standards”; it’s “to whom?”
She said it here.

This is a great example of the practical application of metaphysics and “just semantics” to sex. Oh and while it sounds like it ought to be a pun, if Holly covers the metaphysics of sex here, Geoffrey K. Pullam covers the metaphysics of violins at Language Log.
