It is more, how one defines "nude". Just think of that strange binding the foreskin in the case of greek athletes. So when I write "the athletes were nude ifor the running competition" would for us not discuss if the foreskin is bound or not, for the greek athletes it has the meaning he had to remove that string. Also for the Indonesian native (not all of them just that tribe, I ment) it is not nude to wear a koteka, but we see it that way.
Even the most famous crucifixion event. When I write they put Jesus on the cross, while he is nude. In some times this could mean he is on cross indeed with the loincloth as depicted often.
And finally the last thing if it is for the crucified not a horror to be showed nude, or even penetrated by a cornu, and it seems to be so, then that part of punishment does not work. Also I want to shock and excite the audience, and if for them that is not unusual (saw this on I phone, we did the same last week in the swinger club) we have a problem for the stories....
One can naturally let all the things leaving open and decide the reader what would be showing, but as soon as we picture it, or go into the details, For example I plan to write a new version of the storyline with the abused passion play actor and plan to describe his feelings and how he experience the situation.
