Does the baby come when you hump or when a man sticks his penis in a ladys vaginea?

to have a baby the man penis must go into the vagina and He must then ejaculate sperm which then meets the ovum inside the girl. when the ovum and the sperm get together, then the baby starts to develop. this is a very oversimplified explanation. There is a lot more involved, but just remember that a girl that has had a dick in her vagina could become pregnant.
