Why is it necessary to seperate nudity from sexuality. Can they not exist together. Can they not exist apart.
If your work serves to enable someone elses masturbatory needs why does that make a difference to you. 50 years ago people were using Sears underwear ads, and the wonderful nubile African features from National Geographic.
The nude as art form has existed since the beginning of time, and why is it necessary to censor our own work because someone else my find it erotic or use it for self pleasuring.
I don't find that to be a legitimate argument. You could take a portrait of a beautiful face that exudes so much sex that it hurts. Do we then put a veil over it.
As George said take the pictures that present themselves honestly and naturally and let the viewers do what they want with them.
