"Pulling out before the man ejaculates, known as the withdrawal method, is not a foolproof method for birth control. Some ejaculate (fluid that contains sperm) may be released before the man actually climaxes. In addition, some men may not have the willpower or be able to withdraw in time."
"Not really. Withdrawal, or coitus interruptus as it's known, is not a good way to avoid pregnancy – partly because boys may leak sperm before they come. Also, guys have a dangerous tendency to 'stay in that little bit longer' – until it's too late. Do not risk if you are not ready to have a baby. You need to visit a health worker to decide which contraception method(s) works for both of you."
