Is sexy painful for anyone else?

SmA

I had my baby on the 1st but I’m hoping someone else has tried sex so far lol. We’ve done it about 10-15 times so far and it hurts! Not my vagina, but my cervix! My partner is very big but I had gotten used to it over the years and actually enjoyed it and there were positions I could do that didn’t hurt my cervix but now every single position hurts and he can barely get halfway in before my cervix starts hurting? Why??? Also a few days ago he actually ended up ripping me which is odd because I didn’t have any tears when I gave birth
