Oooh, ladies, this is SOOO funny! XD I honestly can't think of a moment that was caused by "lack of knowledge"... although, when I was little I did have some weird misconceptions about conception and childbirth. I knew that to make a baby, something from the man went into the woman. Naive little thing that I was, I thought it was something that happened when a man and woman kissed or held hands during the wedding ceremony!! I was also convinced that when a woman had a baby it shot out of her belly like a cannon, and the doctor had to be there in order to catch it.
