When I first learned about condoms, I learned that they prevented the HIV virus from getting from one person to another. I was old enough to have learned that viruses and sperm were both very small things, but I hadn't realized that sex wasn't only to just make babies, so I spent a very long time trying to figure out how the condom stopped the viruses but not the sperm. I finally asked someone and was only more perplexed. Why would you have sex if it didn't result in a baby? And if you wanted to have a baby then you wouldn't be safe from HIV! (I didn't realize there was a test that could tell if you had HIV or not.)
