NGL, I am absolutely on board for this level of granular control. Some people want to actively see nudity, but don't want to see that which they aren't attracted to, like gender preferences. It would be nice to almost see it as layered tags, where the top of the heirarchy would be "Porn" and then there is a series of sub categories in which you have more granular control over, such as sex. But the more control you give, the worse the user experience is going to become. Imagine everytime you post, you have to double check the appropriate tags. I already have minor issues with how Lemmy does post creation compared to Reddit, and don't want to see it get really out of control. However, I agree with the original post concept: a global NSFW tag is not enough.
