As an 84 year old man and poster boy for skin cancer. What I see is nudity used in relationships with sex. Every nude man is to hide his sexual feelings. And on photos please. Korea the women nurse their children in public. Japan has bath houses are nude. The Greek gymnasium means all participants are naked. I feel what they are saying is avoid sexual content. The Christians are objecting the sexual content. The bible reads that the first time a husband and wife give each other their naked bodies to each other it is the beginning of a lasting covenant. I would consider their point of view.
