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.
Porn has been around probably as long as humankind. Before there was streaming video, there were erotic cave paintings, and all the clever media in between. Over time, who is pictured and what they are doing has evolved, and varied between cultures, but the gist has been the same. Porn displays sex acts in order to arouse the viewer. Because of the bias of the industry toward male viewers, most of what is shown is usually the female body and the male genitals. The focus is usually on the sexual acts themselves, and less so on the surrounding scenario or the relationship between the individuals. Pornos can depict any kind of sex, from gentle vanilla sex to really aggressive or fetishized sex. If what you see is really explicit, it’s usually referred to as “hardcore,” whereas “softcore” is something closer to what you might see at the movie theater. Want more sexy inspiration?
