Amateur pornography is when people, who are not professional actors, make videos or take pictures of themselves doing sexual things. This means that instead of being paid to do it like in movies, they do it for free because they enjoy it or want to share it with others. Sometimes they do it alone, but sometimes they do it with other people. It's important to remember that making and sharing amateur pornography is only legal if everyone involved is over 18 and consenting to the activity. It's important to understand that these types of videos and images are meant for adults only and should not be shared or viewed by children.
