In some forms it is beautiful but other then that it is just porn
its not porn unless they're engaging in sexual acts.
I find the human body beautiful, and wonderful. I see nothing wrong with nudity in art. Its better than looking at pictures of skinny ass people, art depicts people how they really are. Some are curvy, some are "wide", some are tall, short, skinny, "awkward", etc etc. It shows us the many forms of the human body and thats a positive thing.
