Reminds me of my son at about age 8. We had done some early "sex ed" at home, you know, just answering questions as they come up and providing a little extra information each time. We'd gotten into a discussion of eggs and sperm on one particular day. He was apparently "digesting" the information, because a short time later he came up to me and asked, "What do those little "squirm" look like anyway?" Well, my little boy is 21 now, and we still tease him about the "squirm!"
