Painful Sex

I (26F) have been dating my boyfriend (27M) for a little over a year. We had consistent sex since day 1, but it’s been about a year in now and all of a sudden I have pain with sex. My bf is on the bigger spectrum, but I was able to take it just fine. I went to the Dr, Pap smear, tests all came out normal. I am SO sore after sex, and at times when he goes deeper I feel a sharp “pokey” feeling, and it’s unbearable at times. I still take it because I enjoy having sex with my bf and we both are highly attracted to each other. We have sex 1-3 times a day for days at a time. And we also take breaks when I’m sore. I took a week break, and I still felt that stabbing, poking sensation inside me. It’s not my boyfriend it’s me, and I’m not sure what I am dealing with! This isn’t normal and idk what to do now. Please help.
