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?
