They also help protect against sexually transmitted diseases. Condoms are sheaths of thin rubber or animal tissue that fit over the erect penis during intercourse. Condoms catch semen before, during, and after ejaculation, thereby preventing sperm from entering the uterus. Latex condoms are believed to offer better protection than animal tissue condoms. The use of condoms is sometimes faulted for interfering with the spontaneity of sex, and some say, for decreasing sensation.
Condoms are highly effective if used properly.
Condom breakage is usually due to improper use. Condoms are to be used only once and then thrown away. Using a substance like Vaseline to lubricate the condom can contribute to its breakage. KY jelly is a proper lubricant. Condoms are easily obtained at most drugstores and are reasonable in price.
