These are the methods that some anti-birth control advocates call playing God, since we deviate the natural occurrence from happening.
Natural birth control is also available to people who do not believe that science should dip their fingers in the natural ways of man. Some of the methods include behavioral methods, fertility awareness, coitus interruptus, avoiding vaginal intercourse and abstinence during fertile weeks.
Natural or artificial the important thing about birth control is not how people do it but why, if you take a look at our present situation some families barely make enough to get their children through high school.
Some families are too broke to afford three square meals a day. Without a doubt birth control is needed in our present society for us to provide the next generation a better future.
