When a girl can pregnant?

Answer 1

Sperm from a boy's penis must get inside the girl's vagina during her fertile time of the month. Usually, the penis becomes hard and enters inside the vagina, then the boy's semen, which contains his sperm, ejaculates into the vagina. If the sperm find an egg to fertilize, the girl becomes pregnant with a child. I say usually because the penis doesn't really have to enter inside the vagina to make the girl pregnant. Even a little sperm from the tip of the penis rubbed onto the outside of the vagina could find it's way inside and make the girl pregnant.
