How adult are you wanting? Because there's always Fakku books.

@kurosov On the flip side, Amazon's bad enough on removing works without notice or sufficient explanation, I don't blame publishers for shying away.
You don't just give up on what is far and away the largest market if you wanna make much money.
As to the other adult content, I'm sure it's how they have them categorized. Amazon specifically seems to treat LN's under YA fiction rules, rightly or wrongly.
I expect this is so. After all, there are plenty of smut writers on amazon.
