I am terrified about his size?

We had been dating for a few months and I feel it's time to give me free pass to have sex. I only had oral with him and I can barely fit half of it in my mouth. He is a big guy and his penis is enormous. I get terrified thinking about him entering my vagina.

I can barely put a finger inside my vagina and the thought of him putting his penis inside it terrifies me.

Should I just say no for sex and continue to please him with my hands, mouth and tits? Or should I try to have sex.

The problem is that I know once I let him go inside me, even if I scream in pain he won't stop.
