A childhood belief about rude bits

When I was little I thought that boys had vaginas too even though I had to take baths with my brother. I just thought he was the only one in the world who had a penis. So anyway, when I was twelve I was at some boys house and he was in the bathroom and I had to come in 'cause I left something in there and had to get it out (can't remember what) I was confused why he wouldn't let me in, because when I was liitle, my sisters and my brother always let me in, so I didn't know why he woudn't (I'm a stupid girl). Anyway, eventualy, I came in and was shocked to see that he hada penis too! So I just thought that everyone got one when they got their period. This screwed up my whole idea about sex. Before this,m I thought that you could just get pregnant anytime, and "sex" had nothing to do with reproduction, that was just when you kissed naked with a boy. So I made a new theory: you couldn't get pregnant until you grew your penis (when you got your period) and the baby would come out the tip. For like a year, I was skeptical if I wanted to have a penis. I kinda liked my vagina. Well, it didn;t take to long to figure it out. I remember when at a family reunioun I started talking about it wit my cousin (who's my age) and my uncle (who's not much older than me). When they heard what I believed, they laughed so hard! I can remember my uncle just lauging so hard he couldn't breathe, my cousin didn't think it was that funny, but she laughed, They quickly told me the truth, I was so relieved. My uncle still makes fun of me for this.
