As a child, I thought that by getting married, you would be able to have kids and if you weren't married, then you wouldn't be able to have kids.
My logic was this: Since you a man and a woman to make a baby, the only way for them to "connect" was by kissing. And since I knew that the bride & groom kissed at weddings, the saliava in the kiss would mingle and when the lady swallowed it, she would have a baby.
And in case you're wondering, no, I didn't know about "sex", then.
