What is the best type of protection during sexual activity?

If you choose to have sex, latex condoms give you good protection because they are barriers - something that keeps you away from your partner's sexual fluids. Other birth control methods only protect you from unwanted pregnancy. Using a condom is NOT 100% protection against pregnancy or STIs--only abstinence is--but a condom offers the best protection from STIs and pretty good protection from pregnancy if you do have sex. The best protection is to use birth control pills or other reliable form of birth control to prevent pregnancy AND a new latex condom with each sexual encounter to protect against STIs.
