Well the correct term to make a baby is called sex. there are 2 kinds: Sex and Safe Sex. Safe Sex is when men use a condom, the condom is used for protecting their sperm which makes the baby, this prevents the sperm from coming out. So if you want to make a baby you don't use a condom. Sex is when a men puts his groin in the women's vagina and the sperm is released. Sperm goes to the uterus and fertilizes the women's egg and that creates the baby.
