Condoms can be made from different materials, so it is important to know which material works best. Condoms made from animal skin will not protect you from spreading or acquiring sexually transmitted diseases. Condoms that are made from latex or polyurethane are the only ones that can stop STD viruses from passing through.

If you use a condom, it is also important that you use it properly. An improperly fitted condom can be torn, making it ineffective in preventing STDs or an unwanted pregnancy. When purchasing condoms, be sure to check the package to ensure it's not ripped or torn as well as checking the condom's expiration date.

Another type of barrier you might wish to consider is one that is used for oral sex, usually called a dental dam. A dental dam is a square or rectangular piece of latex you or your partner can put over your mouth when engaging in oral sex. This will prevent fluids from passing between you and your partner.

Another form of protection that women should use is a water-based lubricant. Products such as K-Y Jelly will help prevent the tearing of skin during sexual intercourse, which can also help prevent you from acquiring an STD. When there is a lack of lubrication, the delicate tissue inside the vagina or anus is at risk of being torn. Even small tears during sexual intercourse can allow an STD to enter your bloodstream.
