When you use condoms correctly and every time you have sex, they help prevent pregnancy and STDs (sexually transmitted diseases, also called STIs or sexually transmitted infections).

Remember:

• Use latex or polyurethane condoms.
• Check the condom and its wrapper before using. Make sure there are no tears or defects and that it is not expired.
• Do not keep condoms in your wallet. This can break them down so much that they don't work.
• Put the condom on before you start having sex.
• If you are uncircumcised, pull back the foreskin before putting on the condom.
• If you use lubricant, make sure it's water-based or silicone-based. Other types can break down the condom.

How well do condoms work at preventing pregnancy? No birth control method is 100% effective at preventing pregnancy. Using another form of birth control (like the birth control pill, patch, implant, or an IUD) along with a condom will make pregnancy even less likely.

Can I get an STD even if I use a condom? Yes. Some STDs (like herpes and HPV) can spread to partners through skin that condoms don't cover.

Where can I get condoms? You can get condoms at a drugstore, grocery store, health center, doctor's office, convenience store, vending machine, or online. They may be available cheaper or for free at community or school health centers or your local health department. You also can search online for places near you that give free condoms. You don't need a prescription or to be a certain age to buy condoms.

Can I use two condoms at a time (either two male or a male and a female) for extra protection? No. Using two condoms makes it more likely that they will break or fall off.

Do I need a condom for all types of sex? You should use a condom for anal and vaginal sex and a condom or a dental dam (a sheet used on the mouth) for oral sex to protect you from STDs.
