Painful af HELP

Ok so I tried having sex for the first time with my bf last night. We have been trying stuff to make me loose because he's the first guy I have been with. When we started it was fine but as he pushed (yeah it's what your thinking) I've never felt pain so extreme!! I literally couldn't continue and had to make him stop cus it hurt too bad. Why does it hurt so much?? Has anyone had this experience? Yes I know if it's my first time it's going to hurt but this was more than just hurt. Is there any way to make it less painful? Was that my cherry that made it hurt? Help me
