Scratchy cervix???

Hey everyone!!

I’m very scared to ask this anywhere else, but here I go.

I’ve had sex a few times with my boyfriend, everything is great but he’s told me a couple of times my cervix feels “scratchy” and honestly I haven’t been able to get that out of my mind :(

I don’t know if that is normal, I can’t find anything like that on the internet. I’ve also found very little blood after we’ve had sex (a couple of times)

He’s very big (as in penis size) and I am very small. Was thinking the blood was from hitting my cervix so much but now I’m not sure if it has something to do with that “scratchy” feeling that he gets. Please help.
