When I was a little girl and wanted to be able to tell which animals were boys and which ones were girls, my mom explained to me that "boys have hot dogs" and "girls have holes". When I got older, she told me to never let a boy put his "hot dog" in my "hole" until I was married and ready to have children, because it would result in a baby. That's all she taught me. Unfortunately, she was one of those people who didn't agree with birth control, masturbation, or homosexuality. I've changed her mind since then, but for the time being, I had to learn all other things about sex from sources such as the internet. My sex ed class in middle school wasn't even a big help. It was abstinence-only, and they never even told us what sex was or what condoms were. They basically just told us that sex was bad and that whatever condoms were, they tended to not work.
