orgasms

my bf ate me out today and it felt so so good and i was shaking and moaning and he was fingering me also, and i feel like i was close to coming but my vagina hurt and felt really sore so i made him stop. like it felt good but it also hurt. is this normal? and why cant i orgasm for some reason? i don’t want my bf to think he’s doing something wrong bc he’s not at all.
