People may use birth control for several reasons. Perhaps a man and woman wish to have only a few children so they will have enough money to give those children good food, clothes, and education. More children might mean less for each child, so the parents use birth control to limit the number of children they have. Or maybe a man and woman do not want any children at all in order to focus on their own lives, jobs, or each other. Other couples may use birth control to make sure that they do not have too many children in too short a time, an idea that is called "spacing" their children. This may help them take better care of their children. Still another reason is that a young couple may not be able to afford having a baby until they are older and have more money or better jobs. This may be especially true of younger people who are still in school and probably not married. By using birth control, the couple can grow closer and strengthen their relationship by having sexual intercourse frequently so that when they are ready to have a baby their relationship is strong and stable. In most of these cases the man and woman want to have sex to be close, to feel good with each other, and to make their relationship stronger. Contraception lets them have intercourse while greatly reducing the chances of a pregnancy.
