Instead of ANY babies, I was thinking that a condom prevented TOO MANY babies from being made. Because of how most animals give birth to many babies at a time, I assumed that humans would do the same, without the usage of condoms, and that condoms allow us to only have one or two babies (therefore, they are ALWAYS used). I thought that there was a hole in the condom that let out a little sperm.
