Your choice of which birth control method to use directly affects your risk for getting a sexually transmitted infection.
Some methods offer protection against STIs, while others offer none.
Remember that just because a method protects against an unwanted pregnancy does NOT mean it protects against infections. Only you and your partner know if STIs are a risk in your relationship. There are over 30 different STIs. The most effective birth control methods for preventing infections are the barrier methods, which block contact or reduce impact from contact with sores or infectious fluids. If you or your partner have EVER had unprotected sex, it's a possibility.
