As many people have already said regarding this topic, violence is an easier thing to explain than sexual intercourse, but there's more to it than that. When we view an act of violence, we immediately see pain and suffering occur in another individual, and children who are developing empathetic pathways in their brain might find such imagery and depictions of violence disturbing, particularly when they reflect upon how they would feel if they were in the position of the victim. Because many children will have already somewhat rationalized good and bad behavior to a basic level by the time they're at least 5 or 6, and they see that violence causes harm to another person, which they recognize as being "bad", they understand the fundamental social reasoning for why acts of violence are impermissible. But sex is a far different story.
