When I was little, and still to this day, my mom tells me the same story.
"Babies are made when the daddy gives the mommy a seed". That's about all she told me, so of course I was very confused and sort of figured out my own conclusion. I thought the "daddy" had a "seed" (like the flower kind), and he gave it to the "mommy", and then she would take that seed and somehow stick it up her butt, and out came the baby! LOL!!
