No, they do not. Condoms
can be damaged if stored incorrectly, have an expiration date, and if they are
not put on or taken off correctly sperm can enter the vagina resulting in an
unintended pregnancy. There are websites that give information on condom use
and your care provider can teach you about condoms.
Remember that only a water
soluble lubricant can be used with a condom, so NO Vaseline!
