anyone know

So a couple nights ago mine & my bf usually have intercourse like always. Well he went to finger me and he barely got the finger tips in and it hurt so bad! Felt like a virgin all over. He got me hella wet and tried again, this time everything went smoothly. Now when we tried to have sex when he put it in it hurt so bad! I ignored the pain ( I told him it hurt but I didn't wanna stop ) never turn down dick lol jk so after a few moments later it didn't hurt anymore. It really only hurts when he barely starting to finger and put in his 🍆. Anyone know what it could be?
