Pornography in the United States is pictures or videos of people doing things that are sexual. Sometimes people make money from making and selling these pictures or videos.
In the United States, it is legal for adults to make and watch pornography, but it is not legal for children to watch it. This is because children are not old enough to understand what is happening and it can be harmful for their brain and emotional development.
Some people believe that pornography is harmful for adults too because it can create unrealistic ideas about sex and relationships. Others believe that it is a form of expression and freedom of speech.
There are laws in place to try to prevent children from accessing pornography online or in other places. The law also tries to make sure that people making and selling pornography are not harming others or breaking any laws.
In summary, pornography in the United States is pictures or videos of sexual activity that adults can make and watch legally, but it is not allowed for children. There are laws to protect children from accessing it and to prevent harm to others.
