this is a really strange question but

my new partner has a really big dick it's 8 inches and i know he isn't lying cos i got a ruler and put it to his dick to check😂😂we haven't had sex yet but things got a little heated last night and we nearly did but i said no as i'm so scared because of how big it is, ive only had sex once before and my partner was 5 inches so there was like enough space, but where's my cervix gonna go like it just stays there right? so when he hits it is gonna hurt? and his whole dick won't get inside me will it? lol this is so strange but i wanna know before i have sex with him
