(CNN) -- The centers for Disease Control and Prevention put out a tweet saying that sexually active men and women should use new condoms every time before sexual intercourse.
They also say to make sure they are not expired and to check for tears or defects.
Wallets are not the best place to keep them because heat and friction can cause damage.
The C.D.C. says to keep them in a cool, dry place.
They also say if a condom is not used correctly, it can increase the risk of getting S.T.I.'s and unplanned pregnancy.
