When I was about 9 and hanging out with the older girls at the boarding school, they were talking about periods of which I knew nothing but pretended I did. They convinced me that boys had periods too and had pads shaped like hot dog buns to fit over their penis to catch the blood. I think I believed that until I was 13!
