How do you go from completing a pap smear to being able to have sex?

A few years ago, I did pelvic floor therapy and it helped me complete a pap smear even if it took a long time. That was last year. I rarely work with dilators now, but I recently started seeing someone. It is going well, and I'm happy.

This is the first person I've dated and we both agree about taking things slowly, which is good. However, I'm afraid of sex still, I tell myself if I completed the pap smear then I can probably have sex but I am not sure how it could be different and what else I should do to prepare. I am sad about what would happen if I tried and it failed.
