Nudity taboos started largely with Queen Victoria. I mean, if people were meant to be naked, they'd be born that way. My father and I were both born wearing coats. You do have a choice!
So yes, nude human forms are beautiful, though to some degree I expect the depend on gender and orientation. That said, we must never forget how Janet Jackson's nipple corrupted an entire generation of youth.
The nudity-is-porn campaign is completely dependent on people believing that a person not wearing clothing is somehow inherently sexual in nature. I change my clothes twice a day... I must be quite the perv.
So basically, sex is sex, nudity is nudity, and beauty is in the eye of the beholder.
