Should I do it??

So me and my bf have been going out for almost 7 months now. And we've kissed, and some other sexual things. But we haven't  had sex yet. We both agreed the we wouldn't have sex until we were married. We made a promise. And honestly temptation has been a bitch. Even had a pregnancy scare. But anyway. We've came close but we usually stop because it starts hurting or we say no because of the promise. We both want it. Just don't want to break our promise to each other and most of all our promise to God. What should we do should we just get it over with?? I also kinda feel like I have to. He's going off to college. And I don't want to lose him and I want to give myself to him. He says he's never going to married even gave me a promise ring but still!!?? It might just be my insecurities but yea. HELPPPP!!!! He's my first love and my only love.
