But regardless, condoms are shown to be 99% effective in stopping an unwanted pregnancy as long as they don't break. If they do, you're in trouble, but if not, then you will most likely be fine. Also, condoms are the only form of birth control that offers any defense against sexually transmitted diseases (like HIV/AIDS, herpes, etc.) although it's best not to try it out.
In terms of birth control, the most effective means are usually the birth control pill or injection from a doctor, since they remain active over a long period of time and have no chance of "breaking" during intercourse.
