When I was young, I knew that men had penises and women had vaginas and that the semen went into the vagina to make the baby. I wasn't really sure how the semen found its way into the vagina because to my knowledge, which happened to be based on some soft-core porn that I had stumbled across, the man rubbed his penis against the woman's stomach area during sex.
