Jealous of not being my boyfreinds first :/?

Hey, try not to dwell on it. At least he was honest with you. The important thing is that he is with you! Are you anxious because you have not slept with him yet? If this is the case, don't be. A lot of guys tend to have sex earlier than girls anyway, I know that was the case for me and a lot of my friends. Do you think what's bothering you so much is more the thought of him with another girl, which is causing these feelings if jealousy, rather than it being about sex? At the end of the day, he is with you, he obviously cares about you, and that was in his past. It's not like he has cheated on you, so try to let these feelings go, as it is only negative energy :)
