Sexually active advice

Hey everyone!

My boyfriend and I are both 17 (we are of age to legally consent to each other). We are about to have sex for the first time, and I’ve been on birth control for a few months. Would it be okay to not use a condom? We are both STD and STI free. Would he be able to cum inside of me also? I obviously don’t want to get pregnant, however I take the pill. Specifically, I’m on tri sprintec and I don’t miss a day.
