Am I ready?????????????????????????…

Im 16 and my boyfriends 24 im a virgin. He wants to be my first and i want him to be my first, He said that tonight his roomates will be out at a party and we can do it then. He has protection and im on the Pill. I recently caught him cheating but he promises me it wont happen again and hes sorry, I believe him. Im a junior in high school i take two AP cles have a raw GPA of a 4.0 and im preparing for this night already, i want to but i dont kow if i should. I love him with all my heart and weve been together since i was 14 thats two years its going to be 3 next week. Should I? Im responsible enough to i know that. But im not to sure if i should.
