The bottom line is this: Nudity does not equate to vulgar or crude content. It can be beautiful, unique, and a piece of art meant to be admired, not censored.
The most oft-violated is the one regarding nipples — namely, men can show 'em, but women can't. (And when they do, the offending photos are swiftly removed.) But there's one artist who is working to free the nipple in the hope that nudity can be normalized, not policed: @claudiasahuquillo
