That's what I was addressing with the "small audience" or one-to-one messaging. So long as the sender is sending to a small number of specific individuals (i.e.: small subreddit or DMing small number of people) it should be unregulated.

The consensus is that humans just can't maintain meaningful relationships with more than 150 people so that should be the "small" threshold. The moment the number of viewers/receivers is more than that, it becomes a felony if they fail to follow regulations and notices to users. So if a private group chat grows to have 151 users then everyone sending nudes in that chat is criminally liable unless the group chat has the neccesary warnings and links to where people can get help and moderation to make sure shared content is consensual and legal as well as making sure participants are of legal age.

For "children", the solution is enabling parents to regulate what content kids consume (not just porn but anything really).
