Hey @enderlouis, it's Castleberry on the community account. I'm glad you read my comment here. Even some eroticism is ok if it's done tastefully. I would recommend using a pretty tame thumbnail and put your more daring images further down the post. If it's tasteful and not too much nudity then you can usually slide without the NSFW tag.
But it's always best to be on the more cautious side about using that tag. In art, nudity is an expression and i for one, support that expression. But there's a difference between art and porn. So.... if you are in doubt just use the NSFW tag. We look forward to seeing your project!
