Hentai, anime and manga are all forms of animated storytelling that come from Japan, but they aren't the same. Manga and Anime are story styles with distinct characters, animation styles, and story themes. Hentai draws on some of these styles, but for pornographic purposes. Hentai is animated and the characters are drawn with great XXXageration. Female characters are often extremely thin with enormous eyes, while male characters usually have massive cocks and outrageous muscles. Because it's fantasy, monsters also get to have their fun. When a monster have sex with a woman, it usually breaks all physical and known boundaries of human sex. Bear in mind that hentai is fantasy, and often in hentai lines are crossed that would never be acceptable, legal or even physically possible in real life. Many scenes include rape and violence, and it's an important reminder to recognize your limits and acknowledge those of others.
