Condoms are convenient and easy to use.
The condom is a thin shield that is worn on the penis. It traps the semen expelled from the penis during intercourse, preventing sperm from entering the vagina. A man must put on a condom while he has an erection but before intercourse. Afterward, he should withdraw immediately to prevent leakage. Although condoms can be effective, they sometimes break during intercourse.
