Condoms are very effective in lowering your risk for most sexually transmitted infections (STIs); however, they are only 82% effective with typical use in preventing pregnancy. This means that out of 100 women, at least 18 will become pregnant in the next year. But if condoms are used perfectly every time a couple has sex, they can be up to 98% effective.
The male condom works best to prevent pregnancy when it is used along with a highly reliable method of birth control such as an implant, IUD or the Pill. If you choose to use condoms alone to prevent pregnancy, make sure that you have a prescription for Emergency Contraception or you know where to buy it since condoms can break.
It’s great that you are thinking about contraception before having sex. Other things that are important to think about include whether this is what you want and whether this is the right time in your life. You should also think about how you will feel afterwards. It should be a decision made without any pressure from your partner or friends.
