Daddy sticks his penis into mommy's vagina. A vagina is a third hole on a woman. It is used only for sex and it is in between the anus and the urethra (another hole used for sex). Then daddy's penis emits this thing called semen (it's not pee) and then a baby grows in mommy's uterus (not stomach) and then mommy pushes the baby out of the vagina (not her anus). Oh, and condoms are where the daddy puts something on his penis and it stops the semen from going into mommy. Oh, and Dick is another word for penis. That should about cover it. Remember that, and you won't get made fun of in middle school :)
