Worried It Won’t Fit

I’m a virgin and I’m going to lose my virginity in a few days. The guy I’m losing it to is not a virgin but he says he will take his time and he wants me to have a good first time. I’m ready to do it and I want to but I’m worried that he won’t fit because I’m tight. I can fit one finger inside but can barely fit two. I’m also pretty sure my hymen is still intact as it visibly covers my vaginal opening. I want my first time to go smoothly but I’m so worried he won’t fit. Any advice?
