Pornography, often called "porn" or "porno", refers to sexually suggestive material like pictures, videos, text, or audio created to cause sexual arousal. It has existed in various forms throughout history, from ancient cave paintings to modern virtual reality. The easy accessibility, affordability, and anonymity of online pornography have led to its widespread consumption. As of 2024, roughly 4 million websites offer pornographic content, constituting about 4% of all sites on the internet.
Pornography's effects are a subject of ongoing research, with findings ranging from negative to positive impacts on individuals and relationships. Some studies suggest links to negative outcomes like depression, anxiety, addiction, distorted views of relationships, and increased aggression. Other studies point to potential links to brain changes related to addiction, and increased anxiety or distress. Some research indicates that pornography consumption can correlate with less relationship and sexual satisfaction. However, some research also indicates potential positive outcomes, such as increased sexual intimacy between couples. It's important to note that research in this area often struggles to establish causation versus correlation.
