Okay kiddo, so you know how in different countries and states, there are different rules and laws that people have to follow? Well, that's true when it comes to pornography too.
When we talk about pornography, we mean pictures or videos that show naked people doing things that are sexual. Some people think that pornography is bad for different reasons, so governments decide what kind of pornography is allowed and what is not.
For example, in some countries and states, it's illegal to make or distribute pornography with people who are not adults (18 years or older). They also have rules about what kind of sexual acts can be shown in pornography.
In some places, it's illegal to show any kind of sexual act between people of the same gender. Others allow it but have strict rules about it.
Other countries and states have different rules about how pornography can be made, such as making sure everyone involved has given their permission, paying fair wages to those involved, and making sure they are safe.
So, basically, every place has different pornography laws and rules for making, distributing, and watching it. It's important to follow those laws to stay safe and avoid getting in trouble with the law.
