A childhood belief about sex

I have no memory of this, but my teacher shared it with me my senior year in high school. When I was in kindergarden, I told Josh, a little boy in my class, that I knew what sex was. When he asked me about it, I told him that it was to spit in someones hand. Josh went home and told his parents(my teacher). A couple years later, the teacher had another child, Megan, who was just becoming curious about sex. They were watching t.v. and the 'World's Sexiest People' was showing. Megan then asked what sex was. This daddy, becoming uncomfortable with the subject, blurted out the answer that I told Josh all those years ago. My childhood conviction ended up being a family tradition. I had no idea, but I think that I might tell my children the same thing.
