These tears allow disease germs to pass more easily from one partner to the other. Some experts believe nonoxynol-9 may kill the AIDS virus during intercourse, too. So you might want to use a spermicide along with a latex condom as an added precaution in case the condom breaks during intercourse. Condoms with spermicides have an expiration date. Pay attention to that date.
Spermicides generally come in the form of jellies, creams or foams.
You can buy them in pharmacies and some grocery stores. You can also buy condoms with a small amount of spermicide already applied. But some experts believe it's a good idea to add more spermicide to the amount that comes on the condom. If you do add a spermicide, place a small amount inside the condom at its tip. After the condom is on the penis, put more on the outside.
