"Using two condoms at the same time-either two male condoms or a male and female condom- is not a good idea as the friction may result in one or both of the condoms tearing. If you want to take extra precautions against pregnancy when having sex, and are concerned about the possibility of a condom breaking it is better to use another form of contraception. For example, using a contraceptive pill, patch, vaginal ring or IUS as well as a condom will ensure that you both have double protection against pregnancy as well as protection against STIs."
"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."
"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."
