23 Best Adult Anime on Crunchyroll (Jan 2024)

Whenever adult anime is mentioned, you’re probably thinking of hentai, but there is a difference between the two. Hentai, to put it simply, is just porn and nothing more than that, whereas adult or mature anime is more of an anime with bold sexual themes although its main plot may not exactly be about sex. So here we’ve made a list of the sexiest adult anime that you can find on Crunchyroll. For obvious reasons, you may be a little reluctant to agree that you actually like them, but you just can’t deny that these raunchy shows are entertaining as hell.
