[Method] Barrier methods [Consideration] 
Condoms are more likely to prevent pregnancy if you use them with a spermicide or another birth control method. If the condom breaks, you will need to use emergency contraception. Male condoms are inexpensive and easy to get without a prescription. Male condoms give teen boys control over their STI risks and lower the risk of becoming a parent. Female condoms cost more than male condoms and can be difficult to use properly. A diaphragm or cervical cap with a spermicidal cream, foam, or jelly can be difficult to use without first learning how from your health professional.
