What's your question: Since you're sexually active, the important point is that you're using birth control of some sort, assuming that you don't want to become pregnant. However, unless you make him wear a condom each & every time, you're still at risk for sexually transmitted diseases/infections. Be sure to chat w/your Family Doc or GYN about getting HPV vaccine to prevent or at least lower risk of cervical cancer.
