I used to believe that spermatozoa was like a tongue that came out of the urethra into the woman's vagina, aggressively knocking loose an egg which actively charged it into generating a fetus. I used to believe it would then retract back into the shaft of the penis, pulled by the winding of a spindle inside the body cavity. Something akin to an emergency fire hose.
