External condoms –known as male condoms- are one of the most popular forms to prevent pregnancies and protect against sexually transmitted infections (STIs). Just slip it on the penis. External condoms (male) lower the risk of STIs by keeping sperm inside the condom and out of the vagina, anus or mouth. (There are also internal condoms (female) that go inside the vagina or anus.) External condoms (male) come in hundreds of shapes and sizes. You can also buy them with lube and without.
Types of external condoms (male):
Spermicide. These condoms are lubricated with a chemical that kills sperm. They are not recommended for oral or anal sex.
Spermicide-free. If you or your partner is sensitive to spermicide, look for spermicide-free condoms. Condoms have very few side effects. This type has even less.
Latex. Latex condoms can stretch up to 800%. These are the most common condoms. But do not use them with oil-based lubricants. Oil-based lube can cause the condom to break or slip, increasing your risk of pregnancy or STIs.
Non-latex. If you are allergic to latex or like oil-based lube, then look for non-latex condoms. They are usually made from polyurethane, other synthetic high tech materials, or natural lambskin.
