My wife will not pose nude anymore! May be when she was much younger! She is 62 now and knows better. I would have zero problem if she had posed for nude pictures in her youth. All that tells me she was so beautiful, she was in demand as a model. I have no problem with beautiful women in great shape. It just tells me they value their own body.
Yes, the idea of modesty and chastity are archaic. Lady Gaga and Madonna are the role models, the zeitgeist.
